10 kW Electric boiler – What are your options ?

At Flexiheat UK, we have various options for your 10 kw electric boiler requirements. We do a full range of 10 kw electric central heating boilers, that can either be run off a 240 Volt / Single Phase electric supply ( the most common household electrical supply voltage for the UK and Ireland ) or 415 Volt / Three phase electrical supply. These 10kw electric units are suitable for underfloor heating systems or central heating hot water heating applications as well as domestic hot water installations when coupled up to an indirect hot water cylinder. Our 10kw electric boiler offering are often used in garden rooms, cabins or flats.

10 kw electric boiler; 9kw electric central heating boiler; slimjim electric flow boiler; electric flow boiler

Our closest output to a 10 kw electric boiler is our model ” FHEL9″ which is actually just under that value at 9 kw of output, but normally most home heating systems are oversized, as they normally take into account the worst case scenario of it being minus 5 Degrees C, which in the UK winter is vary rarely seen to be honest, thus we’d be very confident that a 9 kW output electric central heating boiler would suffice for your requirements

However should you require 10kW electric output, then we do our model FHEL14 which is rated to an output of 13.5 kW, which is slightly over in output value, but please remember these electric wet central heating boilers have a modulating output, which means it can modulate down to 10 kW of output – for more information on this model and our full range please see this page – https://www.flexiheatuk.com/product/electric-central-heating-boilers/

10 kW Electric Boiler Efficiency & Benefits

Our electric boilers have a  99.5% efficiency rating which is better than any gas or oil boiler and benefit from well arranged touch display and control panel for our FHEL9 model. This touch screen ensures both simple and intuitive control of the boiler is achieved.

Fluent regulation in low power output steps of just 1 kW (1,000 Watts ) ensure that the heating load requirement is appropriately matched, also ensuring even greater heating efficiency to the wet central heating electric boiler system, be it underfloor heating or a radiator system.

The modular digital control assures optimal operation of this 10 kW electric boiler in a way that optimizes electric energy consumption with the rated thermal output of the electric boiler.

These 10 kw electric boilers come complete with an integrated “ERP” energy efficient compliant heating pump and integrated 7 litre expansion vessel, making these electric boilers what is commonly know as a system boiler. This allows you to have a “sealed heating system” meaning that no feed and expansion water tank is required in the loft or at high level – which can be prone to freezing or bursting. It also means  installation is made a lot more tidier and compact, as all required components are within the boiler casing.

These electric central heating boilers can be controlled by an “OpenTherm+” thermostat or controller e.g. a nest controller etc ( control your 10kw electric boiler on the go, from your phone) giving your greater control over your electric wet central heating boiler.

They can also be controlled by a standard room thermostat or weekly programmer – the decision is yours to make.

Technical details of our 10 kw electric central heating boilers

Below you can see the technical data for the Flexiheat “FHEL9” and also the next size down and up in this range of touch screen electric boilers for central heating –

Please note as these electric central heating boilers, can be wired in either three phase or single phase, the below table shows both parameters. For example, the maximum rated current for the FHEL9 electric boiler, when wired up using a three phase electrical supply is – 3 x 14 Amps per phase, and when wired in single phase, the figure is 1 x 42 Amps.

Boiler pressure keeps dropping ? What to check

/in /by

Boiler Pressure keeps dropping or continually low ? 

Why does my boiler pressure keeps dropping ? This is a common question , and following in this guide we’ll take you through the most common boiler problems, what to look for , and actionable things that you can do to fix the dropping boiler pressure. Most of the time these fixes are easy , that can be done by yourself, as you don’t need to be an expert in order to do a little troubleshooting on your own.

By following these simple steps , you should figure out what is causing your low boiler pressure , and why it continually keeps on dropping , in no time at all, before having to call a plumber out. Some of the fixes can be done by you , whilst others you may have to get a plumber or heating engineer out to look at your heating system as you may have a boiler leak causing it to lose pressure.

work through the following table of contents in an orderly manner

Things to check on the boiler

Firstly you need to check your boiler pressure gauge , and see what’s it’s reading. This gauge is most commonly built into the boiler, or underneath it and should look like this or similar –

boiler pressure keeps dropping,combi boiler pressure keeps dropping,boiler pressure keeps dropping to 0,ferroli boiler pressure keeps dropping
The Heating System Pressure Gauge – The fist thing to investigate as why your boiler pressure keeps dropping

In the picture above the red marker on the gauge is just an indicator of where the level should be, the thin black marker is the actual pressure of the heating system. A pressurised boiler system or a sealed central heating system needs a certain amount of pressure to work, normally about 0.5 Bar – 1.5 Bar, although some will continue to function with far less pressure. If this pressure reading is lower than the recommend pressure level, this means you heating system water pressure is low and that you have low boiler pressure which needs to be topped up so the level is above the red line on the pressure gauge normally via the filling loop, which will fix the low boiler pressure.

It is usually best to contact a plumber if you have any concerns about your boiler losing pressure or are unsure of how to re-pressurize the system yourself.

But before that is done, you really need to establish why the boiler keeps losing pressure as you may have pressure loss in the pipework i.e. copper pipe via a leak or even a leaking radiator valve, gland nut or heat exchanger etc.

Combi boiler pressure keeps dropping ?

It doesn’t matter whether your boiler is a heating or heat only boiler or a combi boiler, as we are talking about losing water pressure on the central heating system here .If your combi boiler is losing pressure on your domestic hot water side of the boiler ( this is you hot water that is provided to your hot water taps , showers or bath taps ) then this will be a mains water pressure problem, and you would need to consult your water supplier.

First thing to check –

Is there air in the heating system?

This is an easy thing to check yourself. You just might be able to diagnose your problem with just a few checks,

Before you do anything, try bleeding your radiators. But before you set off to do this, a top tip is to have a towel or rag to catch any drips from the radiator air vent, as the water form the heating system can be black in colour and stain anything that if falls onto. To bleed your radiators, use a radiator key. Find the radiator air vent and slowly turn the radiator key counter clockwise until water starts dripping out, this releases the trapped air and lets hot water fill that void or space in the radiator again, ensuring a nice hot radiator. Always bleed the top floor radiators first and make sure you bleed the radiators in sequence. Bleeding the air from the radiators will then cause the pressure to drop lower again, so check it again after bleeding all the radiators and adjust it accordingly.

If bleeding the radiators doesn’t work, then you may have a bigger issue such as an air lock in the heating system or you may even need to have the heating system itself flushed out. I wouldn’t recommend you doing this yourself , unless you feel completely comfortable, and have the tools and equipment to do it properly. So it’s time to call a plumber for most people.

Second thing to check –

Is there a leak in your central heating system?

Look for signs of a water leak such as a damp floor, leaky pipes, a small hole in a radiator somewhere or a stain on your ceiling, any or all of these signs point to you have a leak on your central heating system, which is causing your boiler to lose pressure. Finding a leak may sometimes feel like finding a needle in a haystack, but it’s worth trying to find it yourself, before calling out a plumber, as most heating engineers charge an hourly rate, which can become quite expensive, should be tasked with finding the leak on you central heating system.

Third Thing to check –

Is the boiler pressure relief valve leaking ?

Is the pipe coming off the pressure relief valve on the boiler continually dripping water ? If so at some point the valve has probably operated and there may be some internal debris that is stop it from properly shutting off again. This faulty pressure relief valve may need to be cleaned or replaced completely and is a fairly cheap repair or you may need to replace this faulty pressure relief valve. This job really should be left to a qualified plumber or heating engineer to do.

Fourth thing to check –

Is the Boiler Expansion Vessel Faulty?

boiler pressure keeps dropping,combi boiler pressure keeps dropping,boiler pressure keeps dropping to 0,ferroli boiler pressure keeps dropping
An external expansion vessel, used in central heating systems

All modern sealed system boilers or pressurised boiler systems use an expansion vessel with pressurised air within the unit, either placed within the boiler but can be located externally too , that accommodates any expansion that is created when water is heated up in the heating system. If the expansion vessel is faulty, it normally means that it will not be able to handle the expanding hot water resulting in the pressure in the heating system rising rapidly and this water will be ejected through the pressure relief valve, once it goes beyond 3 bar in pressure. The expansion vessel’s internal bladder, which is normally made from neoprene rubber (Neoprene rubber resists degradation more than natural or synthetic rubber), must be inflated by air or ideally nitrogen ( when the gas side is filled with nitrogen, and not with air, corrosion is prevented and the pressure loss is even more limited). This level of nitrogen or air, commonly known as it’s charge must be maintained through annual servicing of the boiler or eventually it will dissipate completely, eventually causing the boiler to have continual low-pressure problems and ultimately failure of the central heating system.

combi boiler pressure keeps dropping,boiler pressure keeps dropping to 0,boiler pressure keeps dropping
Expansion Vessel internal picture, showing the “Bladder”

If that doesn’t seem to be the problem, then the next thing to do is find the Schrader valve on the expansion vessel, which looks like an air valve found on a car or bike tyre. Then depress the valve in the centre using a screwdriver or similar. If water comes out of the valve it means that the diaphragm has failed inside the expansion vessel, and you will need to replace the vessel or with some units you can just replace the internal neoprene bladder.

Dropping boiler pressure from Flexiheat UK; boiler pressure keeps dropping; boiler pressure keeps dropping to 0;
Expansion Vessel Schrader Valve Picture & How to Test

If air comes out of the Schrader valve you need to check the pressure of the charge in the vessel. To do this you will need a suitable measuring device, such as a car tyre pressure checker. The air or nitrogen pressure for an internal boiler expansion vessel should be around 0.8 bar ( but please consult your boiler’s operating manual and check exactly what pressure the vessel should be charged to) but this could be higher for externally mounted expansion vessels. To fix this call your local heating engineer and ask him to re-inflate the expansion vessel. This is done by draining off all the heating system pressure first, then then using a pump (like a bicycle type or similar) the expansion vessel is re-inflated.

So what if the boiler pressure keeps dropping after doing this ?

So after your expansion vessel has been re-inflated keep an eye on the boilers pressure gauge, to see that it’s still correctly holding the system pressure for the next couple of weeks, as sometimes the internal bladder that holds the air or nitrogen has a pinhole puncture and it leaks out over days or even weeks , which isn’t always obvious, until you see your boiler pressure dropping.

Pressurizing your expansion vessel should typically be done as part of an annual boiler service, by a qualified plumber / heating engineer. We highly recommend that any work that is required to be done, is not done by a yourself or a novice, as we are dealing with hot water and pressure here, and these two items can cause physical damage to people or the property

Boilers with low water pressure – other things to consider

One thing that people often overlook is that if your boiler has been under pressured for a long period and you’ve been constantly topping the heating system up via a filling loop, then it would have depleted the central heating inhibitor chemicals within the heating system, it is therefore very important to add more inhibitor to the heating system , otherwise your heating system will start to corrode which can lead to a failure of your boiler, in a relatively short period.

Refilling your low pressure boiler heating system

After diagnosing your problem, and getting it fixed, the final step in getting you low pressure boiler back up to the desired pressure is refilling the heating system with what is called a filling loop . On some boilers the filling loop is internal to the boiler but in most systems the filling loop is an external piece of kit, and should be what is termed as a part “L” of the building regulation compliant and looks like this –

ferroli boiler pressure keeps dropping,combi boiler pressure keeps dropping
Part L Compliant Filling Loop

You should only refill your central heating system when the system has cooled down. You simply open the valves up, slowly and wait for the pressure gauge on the boiler to rise to 1.2 Bar to 1.5 Bar maximum (please consult you boiler manual for the recommended pressure that they stipulate).The process is then finished off by closing the valves , thus sealing the heating system from the mains water

Hopefully this guide “boiler pressure keeps dropping” has been helpful, and shown you some of most common reasons why this happens and how to remedy it.

Warm Air Heaters – ErP 2018 Lot 21 Directive Effective January 2018

/in /by

ErP 2018 Lot21 – Guidelines for Warm Air Heating Systems

 

 

What is ErP?

The Energy related Product (ErP) Directive is designed to reduce carbon emissions across Europe. In the same way as on white goods, TV’s and tyres, since September 2015, ErP also applies to domestic and commercial heating products.

The main objective of ErP is to phase out low efficiency products from the market place. ErP also covers electrical powered products, boilers, water heaters and renewable technologies, but for Warm Air Heating applications, where humans are enjoying thermal comfort, then the warm heaters being installed must achieve a seasonal efficiency of more than 72%, from 1st January 2018.

Requirements  for warm air heating :

  • Efficiency requirements (gas and oil)
  • Limit values ​​for nitrogen oxide emissions:
  • ErP Stage 2 for Warm Air Heaters – From 26th September 2018 maximum 100 mg / kWh  for gas fired units and 180 mg / kWh for oil fired units.
  • ErP Stage 3 for Warm Air Heaters – From 1 January 2021 maximum 70 mg / kWh for gas units and 150 mg / kWh for oil fired units
  • Information must be provided freely and publicly

Both our suspended gas unit heaters and our floor standing industrial gas heaters are fully ErP compliant.

And our oil fired heaters are also ErP fully complaint – see here – Oil Fired Cabinet Heaters  or our industrial oil heater range

The importance of being ErP compliant for warm air heaters 

Since September 2015 the Energy related Product (ErP) Directive has impacted boilers, water heaters and hot water storage tanks. Flexiheat UK are committed to ensuring that all products are compliant and all heating professionals understand ErP regulations.

ErP Objectives

The ErP Directive was designed to reduce harmful non-environmentally friendly emissions from energy consuming products. This is to contribute to the European Union’s 20-20-20 targets on climate change and energy.

Targets for 2020 

There are three main objectives for 2020:

  • A 20% reduction in EU greenhouse gas emissions compared to 1990 levels
  • A 20% improvement in the EU’s energy efficiency
  • Raising the share of EU energy consumption produced from renewable resources to 20%

Implementation in two stages:

  1. From 01.01.2018: Space heating annual efficiency η s at least 72%
  2. From 01.01.2020: Space heating annual utilization rate η s at least 78%

Space heating annual utilization rate :  Definition

The space heating annual utilization rate is a key figure that should take into account the actual operation of heating systems. It is not the firing efficiency. The commission responsible for the directive has recognized that heating works on average 85% in partial load operation – i.e. in the transition periods – and only about 15% of the full load operation is required and therefore weights the heating efficiencies. Furthermore, inefficient burners, poor insulation and permanent pilot lights are considered with negative factors. Thus, for the first time, different manufacturers can be objectively compared.

Is a Mandatory if –

Warm Air Heaters are being used to provide thermal comfort for human beings – then the heaters MUST comply under the ErP for Warm Air Heaters – Lot 21 of the regulations

Applications where the ErP Directive for Warm Air Heaters 2018 are exempt:

  • Door curtains
  • Frost protection of perishable product
  • Horticultural heating (i.e. glasshouses)
  • Agricultural heating (i.e. poultry houses)
  • Process heaters/dryers

Information for Warm Air Heating Installers

All Warm Air Heating installers are responsible for ensuring compliance with certain parts of the ErP Directive when carrying out an installation or replacement. Installers have to carry out efficiency calculations for the installed system, provide energy labels and complete the ‘fiche’ document.

Flexiheat UK  is committed to supporting installers with everything they need to complete the fiche and ensure everything is ErP compliant. We strongly recommend that warm air heating installers become familiar with how ErP works.

German Electric Heaters – From Flexiheat UK

/in /by

German electric heaters warm air from Flexiheat UK

With the rising costs of gas and oil, we are more and more looking for ways to cut back on heating bills without sacrificing comfort. German electric heaters are a reliable way to heat the areas of a house, apartment or business unit you use the most, without wasting energy trying to heat your entire building. When looking for the right model, consider the advantages an electric heater can provide.

Our range of German Electric Heaters are well engineered being built in the southern area of Germany, which is synonymous with manufacturing excellence. The units are built to an extremely high standard and are some of the most energy efficient and safest models on the market. If you really think you can benefit from an electric heater in your home, garage, or the office this is the type you should get.

As the saying goes,  “you to get what you pay for”. That is why, we strongly recommend paying that little bit extra for a German made heater to give you peace of mind with its high standard of construction.

Our German factory offer a nice range of electric heaters, from a 3kW model up to and 18kW model. The 18kW model has a version that has high temperature capabilities, allowing it to thermostatically controlled up to 70°C. This German made electric heater unit is perfect choice for use in the heat treatment, pest control industry.

We have found that our 3kW German made unit, after prolonged continuous use, can actually pull 13.1A. We have two options for this. The first being we can supply a dedicated Euro to UK plug adapter, which prevents this or alternatively you can purchase our UK built FF3 unit, which we do not have this problem with. This would be supplied with a standard UK plug.German Electric Heaters

 

 

Why choose to go down the electric heating route

There are several options for heating a room. However, not all options are a practical for some properties. In addition, not all locations have the same energy sources, so that a choice must always be made. For example, for a property without access to mains gas, one can opt for an oil heating system. What if this property is too remote for regular deliveries? Then a great choice or the perfect balance is to opt for electric heating.

We are not talking about electric radiators here, which are wall mounted, supplying radiant heat and an element of convection heat, and tend to be storage heaters that use an electric heating element to create heat retention by warming up bricks or other thermal materials to store the heat until required.

Our German electric manufactured warm air heaters warm the cold air directly, unlike storage heaters, which use heat retention and require a charge up period, which means you’re always trying to predict tomorrow’s weather. With our units, if it’s cold, you put them on and they heat the surrounding air; if it’s not, you don’t—it’s as simple as that. You only use energy when it is needed! unlike storage heaters ( electric radiators) which use a heat retention system – that stored heat is often not required and thus wasted – that’s why we don’t consider these efficient electric radiators.

Below are just some of the benefits of using one of our German electric heaters; –

Clean and green – an electric heater, unlike oil or gas gives off no emissions.   They are 100% energy efficient; converting every bit of the input energy to heat. They also reduce environmental impact compared to other fuel types:

No installation costs – these Electric Heaters do not require any installation. You only have to plug the plug into the socket and the device is immediately ready for use – a  DIY installation as such, unlike wall mounted units.

High efficiency –  an electric heating system is very efficient, because the electricity used is directly converted into heat – there is no wasted energy as they are 100% efficient, which is good for lowering your energy bills.

Additional heating – electric heaters are ideal when the existing heating system is not sufficient or more heat is required in the short term. Moreover, they are the perfect solution in the transitional period, i.e. in spring and autumn, when the temperatures are not so low that the central heating must be switched on

Safe to Use -Electric heaters are distinguished by different safety features such as overheating protection, with a thermostat to ensure full control of the temperature and come with a powder coated covering.

Portability – electric heaters are extremely versatile and more practical in different situations than other heaters. Therefore, they are often preferred by electric heating company or installers.

Quiet and discreet – with the exception of the fan, electric heaters have a very low noise level, therefore making them ideal for smaller rooms heating solutions.

Zonal Heating – because of their mobility, an electric heater is perfect for specific areas that require temporary or permanent heat for commercial properties.

 

Make life easy for yourself, with our German manufactured electric heaters, in most instances all you need is a power socket. However, for larger areas three phase models are also available giving large volumes of heat. There are no exhaust gases or smells – just large volumes of safe, fume-free heat. Electric heaters are ideal for virtually any location including

 

  • Offices
  • Shops and showrooms
  • Hotels
  • Garages
  • Industrial units
  • Classrooms
  • Clinics
  • Building sites
  • Marquees and tents
  • Storerooms
  • Workshops
  • Ships
  • Switching stations
  • Temporary accommodation
  • Modular buildings

 

The amount of space an electric heater can take care of for you will vary. Make sure you read do plenty of research before you buy one. Generally, this information will be displayed in square metres. You can easily calculate the square metres of a surface area by multiplying the length of it times the width, but this is the incorrect method , as you heat a cubic volume , thus you need the ceiling height to get the overall cubic volume to calculate the heat loss of the area – call us with this information- and we’ll run it through our heating calculator size programme to ensure the correct size German electric unit for both you or your happy customers.

You will find that many of our models of electric heaters also are very nice looking. They aren’t going to stand out like a sore thumb. Many of them are very small in size but you will be surprised at how much heat they are able to emit for you. They also take very little time to heat up so you won’t be waiting in the cold for that warmth to start circulating in the room.

Our range of German manufactured electric heaters can definitely offer you the additional warmth that you desire. With their in-built thermostat and two heat settings they will certainly save you energy as well with this high quality German engineering technology unit.

Commercial Boiler

Commercial Boiler

commercial gas boilers; commercial lpg boiler; wall hung gas commercial boilers; commercial boilers in cascade; Worcester; price; vat; job;

A commercial boiler is a pressurized system that burn combustible fuel, either gas (natural or LPG) or oil to heat water that is then used to provide heat to your building. Commercial boilers work just like domestic boilers just that they are larger in output, some people say over 70 kW is a commercial boiler, whilst others say that anything over 50kW output is- there is no hard and fast rule to be honest. Some boilers use the actual hot water itself while others utilise water that has been turned to steam. Be it an hotel, school or hospital boiler, a district heating scheme or any industrial or commercial refurbishment of your heating scheme or project requirements, you can benefit from our vast experience in supplying commercial heating boilers in the UK and Ireland.

Inside the commercial boiler itself, the burner, whether it be natural gas / Propane (LPG) or Oil creates heat that is then transferred to the water via the heat exchanger. The process normally creates either hot water, depending on the type of commercial boiler. The hot water is circulated via pipes throughout your building. The water then enters radiators or other components that divide the heat thus providing the heating you require to keep your indoor spaces comfortable, just like a domestic boiler.

Our commercial boilers have energy efficiency, as you would expect from leading manufacturers and are normally used on pressurised systems

Natural gas is probably the most common fuel used in commercial boilers. Other types of boilers are available that burn fuel oil like diesel or heating oil. There are also boilers out there that use electric immersion heaters to produce heating from electricity-We also supply these

We do a full range of commercial boilers that can do heating and hot water for your commercial premises – these are detailed in more depth on these webpages

Commercial boilers – Gas fired – Natural gas or LPG 

Commercial boilers – Combi -heating and hot water in one unit – Gas Fired – Natural gas or LPG

Commercial boilers – Oil fired

Commercial boilers – Electric powered 

We at Flexiheat have the widest range in the UK, of efficient boilers for commercial heating and hot water applications, that provide maximum energy efficiency and low emissions for your installation.

Common components of commercial boilers

 

  • Burner: A burner is a device for the combustion of a fuel. For example, a fuel oil burner can be mounted on the boiler of a central heating system (oil heating). The burner produces a flame by pressing the fuel oil through a fine nozzle and supplying combustion air with a blower. In the burner start, the flame is usually ignited with an electric arc. The hot combustion gases enter the boiler, which effectively serves as a heat exchanger: the generated heat is transferred to the boiler water to a large extent. Similar burners are operated with natural gas. No atomization is necessary here, only a good mixing of gas and air. The correct dosage of the combustion air is important for a clean and efficient combustion. Ideally, the burner supplies exactly the required amount of air to the flame: by no means too little to allow complete combustion (without the formation of soot or carbon monoxide), but not too much to minimise exhaust gas losses

 

  • Combustion chamber: A combustion chamber is a component in which air and fuel are mixed, ignited and burned to heat the water. The chamber contains the burners and is specially designed to provide a safe and secure area for high-temperature combustion of volatile fuel. The chamber is commonly constructed of steel, cast iron or other heavy-duty metal.

 

  • Heat exchanger: The heat exchanger is an integral component that carries the heat created by the burners to the water in the boiler. Heat exchangers are commonly made of cast iron, stainless steel or copper.

 

  • Controls: System controls allow the user to calibrate water temperature, air and fuel supply mixtures, ignition and internal pressure. The controls regulate when and how often the burner fires, the temperature of the water, the rate at which fuel is used and the quality of the mixture of fuel and oxygen. Commercial boilers can also be fitted with appropriate safety controls that make sure that the internal pressures in the boiler doesn’t get too high, the water temperature stays within a safe range and ensures that the system continues to operate properly.

 

  • Exhaust stack: Also called the flue, the exhaust stack is the series of pipes that divert the exhaust gases away from the inside of the building to the outside. The exhaust stack must be constructed to ensure that any dangerous gases such as carbon monoxide are safely vented away from the interior of your facility.

 

 

Boiler Safety and Maintenance

Commercial boilers can be unpredictable systems containing very hot water under high pressure. Therefore, care must be taken to make sure the boiler is clean and working properly and that all safety systems are functional and ready to work if required. Hot water leaks can pose a serious risk of causing injuries or damage. Commercial boilers can potentially explode in the worst circumstances, which can result in serious injuries or even death as well as significant damage to your commercial facility.

It is imperative that your commercial boiler receives regular preventive maintenance from a professional heating engineer. This maintenance not only ensures the system works correctly and at its highest level of efficiency but that it also works safely.

Here at Flexiheat UK, we realise that finding and purchasing a new commercial boiler is a complicated business. This is made far worse by the confusing terms used to describe boilers. This is our guide to these commercial boiler technical terms, to help make your search easier.

Condensate

The term condensate is used regularly. Throughout the process of producing heat, the boiler will produce some condensation of the flue gases in a condensing boiler. This needs to leave your building or premises normally through an outside wall. In addition, some of the condensation will turn to liquid and need draining away. This is normally through a pipe that connects to your pre-existing drainage system.

Condensing Technology

This term has increased in popularity, as modern boilers are all fitted with condensing technology. This means it is capable of condensing the gas into heat for your business. The benefit of condensing technology is that a lot more of the waste gases are recycled and turned into more heat, which is far more cost effective and better for the environment.

Flow Rate

Flow rate is a term used to describe the amount of hot water that is produced in one minute. This is mainly relevant to combi-boilers, which do both the heating and hot water requirements. The higher the flow rate, the more water produced which means your boiler can work for less time and use less fuel. Essentially a commercial boiler with a good flow rate will save you money on your bills, whilst satisfying your hot water requirements . Commercial combi boilers are the ideal boilers for smaller commercial property applications.

ErP Rating

This term refers to the A++ to G ratings, shown on all new boilers. Referring to the boiler’s energy efficiency as well as its heating and hot water performance, the rating allows you to choose the most efficient boiler. A++ is the highest performing and G is the lowest.

SEDBUK Rating

This term means: Seasonal Efficiency of Domestic Boilers in the UK. It is a percentage rating for boiler efficiency and it has been added as part of the overall ErP rating.

 

We at Flexiheat UK hope this glossary helps make choosing a new commercial boiler a little easier. Don’t let the commercial boiler technical terms give you a headache!

Blow heaters are fundamentally any type of heater that is assisted via a fan – thus sometimes referred to as a fan heaters.  As the term suggests, heat is expelled at a higher rate resulting in faster movement of warm air thus ensuring a more efficient and accurate heat delivery.  There are a range of blow heaters on the market. The most common of these is Electric Fan Heaters  which function by heating a coil or a heating conduct or even ceramic heaters. The cold air is led along this heating coil and heated. A fan is then used to transport or circulate the heated air into the entire room.

Electric fan heaters are usually compact and space-saving, which means they can be used almost everywhere and are super-flexible as far as the location is concerned. Only a power connection and a little space is all that’s required.  They are used for heating rooms such as garages, greenhouses, tents and the like. They are often used as additional heating in the home or living area, because of their fast and effective way of heating the entire room.

Thermostatic control is an important element for controlling any fan heater, to ensure the heat is controlled to the required warmth level, and that the unit doesn’t over heats.


Blow Heaters

A fan heater is suitable to heat locations such as stock rooms in a shop to protect products from damp or freezing, or even heating the shop area to keep the customers warm. A fan heater can also be used as a garage heater warming the location to the desired level.

Common applications for fan heaters

Building industry • Heating and drying out rooms, often in conjunction with a dehumidifier.
Industry • Heating of offices, canteens, stores, warehouses etc.
Livestock • Heating poultry houses.
Horticulture • Heating of sorting areas and greenhouses.
Agriculture • Heating of livestock areas, dairy parlours, workshops and packing sheds.

Other popular types of fan heater are ones fuelled by gas, usually propane or liquefied petroleum gas or LPG, for short. Most gas fan heaters use a so-called piezoelectric igniter. A material, often crystal quartz, which has the property of developing an electrical potential when pressure is applied is housed in a mechanism that allows a spring strike hammer. This action generates a spark, igniting the gas within the fan heater.

Blow Heaters

Common applications of a gas fan heater

Livestock •

Heating of pig and poultry houses and sheds

Agriculture •

Drying of agricultural products.

Horticulture •

Heating of greenhouses and polytunnels (N.B. Control CO2 and CO emission)

 

Control

Temperature control is a desirable feature in a gas blow heater. An automatic thermostat is a popular way to achieve this and some of the more sophisticated fan heater are fitted with a thermostat while others simply have a manual high and low flame control.

Safety

The main drawback of burning propane or other combustible materials, for that matter, in a small and enclosed space is the risk of carbon monoxide poisoning. Carbon monoxide is a product of irregular combustion. It is odourless and it competes with oxygen in the blood, which deprives the brain and other parts of the body of oxygen. Some propane heaters are approved for indoor use and some are not.

The advantages of fan heaters

 

  • Fan heaters heat the room quickly and effectively to the desired temperature.

 

  • No additional work is required to operate a blow heater. Only one socket and some space should be available.

 

  • The purchase costs of fan heaters are manageable.

 

  • Most models are equipped with practical carrying handles or tramples, so even if the case is still warm, they can easily be moved locally.

 

  • The most compact design of the devices allows them to be used in a very small space.

 

  • Due to the existing “cold stage”, the units can be used as a fan in summer.

 

  • Integrated or external time switches allow time-controlled use.

 

  • Many appliances can be used as frost monitors without an external thermostatic control unit.

Commercial Heaters – Your Options

Commercial heaters are frequently used in almost all the industries today right from manufacturing , car show rooms , retail units to warehouses . There is a variety of heaters that serve different purposes. As an unavoidable necessity, it is essential for businesses to install a commercial heating solution in their premises, to either keep they’re staff or customers , or even both satisfied. Commercial heaters can also be used to keep products above certain temperatures to ensure no damage to them , such as frost protection etc.

Installing them may be an easy task as you simply order the supplier or warm air heating installer to do so, yet the most challenging part lies in different types of questions and queries before installing-

Please go through the following points if you want to get the most out of your commercial heating equipment –

 

First of all, make an in-depth assessment of what your heating needs exactly are. Looking at the devices randomly may take you on the wrong route.

 

The following are the most common types of commercial heaters on the market based on fuel types

 

Commercial Gas Heaters and Propane(LPG) Heaters

 

Commercial Gas heaters burn a variety of either natural gas, propane (LPG),  natural gas (NG) or other gaseous fuels to generate heat. Early gas heaters were similar to the Bunsen burner in that both they used a flame to heat air locally. This heated air was spread by convection to warm an entire area. Later, the burner’s flame was used to heat a structure made of asbestos, a strong and incombustible fibre. Although asbestos structures have been replaced by fire clay and other refractory materials, modern gas heaters still operate according to this principle but the refractory materials have now been replaced by a combustion chamber and a heat exchanger, which means that any products of combustion are now expelled via a flue pipe system, being infinitely safer than the early days. They are often Co-Axial flued , or sometimes referred to as room sealed , whereby they take the air required for combustion form outside the building , via a twin piped flue system, this results in higher efficiency as the building is more air tight . Both natural gas commercial gas heaters and propane commercial heaters often use similar designs, the only difference is the gas burner.

Commercial Suspended Gas Heaters – In a Garden Centre

 

According to their radius of effect, gas heating systems can be divided into two types: the so-called gas convector and gas-turbine heating.

 

With gas convector is heaters, which are used primarily for heating individual rooms. The heat generated by the combustion of the gas is then discharged directly to the environment. The gas-turbine heating, on the other hand, is generally used as a central heating system to supply entire buildings

Commercial Heaters – Gas or Propane – Applications

There are a broad range of different applications for gas and propane heaters. Below are just some examples;-

  • Industrial Applications
  • Warehouses
  • Workshops
  • Garages
  • Greenhouses
  • Offices and Shops 
  • Retail Outlets

 

Features

There are a whole host of optional features for gas heaters. Some are indirect-fired, some are corrosion resistant, some are finned and some are even explosion-proof others are designed to provide dynamic power regulation . They can feature custom designs or have a secondary heat exchanger ( condensing warm air heating) for maximum heat transfer. Gas heaters can also be fitted with an external temperature sensors and multiple / independent timing controls to suit the site conditions

 

Commercial Heaters – Oil – Gas Oil or Kerosene 

 

Oil commercial heaters predominantly burn fuel like heating oils such as gas oil or kerosene to generate heat but waste or used oils are also a popular fuel source.

Types

There are many different varieties of oil and kerosene commercial heaters.

Probably the most common are stationary cabinet’s types. These are usually floor mounted and either blow out warm air through their vents or through duct.

Commercial Oil Heaters – Used in a Greenhouse Heating application

Operation

Oil and kerosene commercial heaters transfer heat to a room over a longer period of time and at a slower rate. When the oil burner is engaged, heating oil travels from the tank or reservoir to the burner by way of a pump where it becomes a fine mist mixed with air. The fuel/air mixture is then injected into the burner where it is ignited in the combustion chamber of the heater, which then transfers the heat via a heat exchanger to the space being heated.

 

Specifications

Oil and kerosene heaters use single-phase or three-phase power.

 

Applications

There are a wide variety of applications for oil heaters. Examples include;

 

  • Warehouse & Factory heating
  • Drying,
  • Melting,
  • Annealing or heat treating,
  • Curing or tempering
  • Operations with gases and vapours,
  • Clean water heating
  • Heat process and high-purity waters,
  • Lightweight oils & degreasing solutions,
  • Heavy & medium weight oils,
  • Mild & severe corrosive solutions,
  • Caustic solutions and liquid paraffin.

 

 

Commercial Heaters – Electric Heaters

 

Electric heating systems are  heaters which produce heat via heating wires or heating coils. They can be roughly differentiated according to whether they store the heat, store it in part or deliver it directly or whether the heat is generated by infrared radiation or by the heating of air.

 

Types

There are many variants of electric heaters. Below are the main types

1 – Natural convection

The portable heater with natural convection resembles a standard heater. It settles on the ground and heats up slowly.

Operation

  • Fresh air rises inside the cabinet by convection.
  • The air is then heated by an element.
  • The hot air exits through the openings and rises into the room.
  • There is no fan on this type of appliance.

Advantages

  • The natural convection heater keeps the temperature constant, provided the room is closed or not too large.
  • Silent.

Meets the needs

  • Ideal for use for several hours at a time, for example, at the chalet or at night, in a room when the central heating of the building is switched off.

 

2 – Forced Convection or Blow Heaters

 

The forced convection heater, also referred to as forced air or blow heaters are a very popular model. These heaters are often small and light and distribute the heat with a fan.

 

Commercial Heaters

Commercial Electric Heaters

 

Operation

  • A fan moves the air around the heating elements and pushes it forward.
  • In ceramic models, electricity passes through ceramic plates that store heat in their mass, and then a fan spreads it.

 

Benefits

  • Small and light.
  • Rather stable temperature in a closed room.
  • Heat sensation faster than with fanless model.
  • Allows directing of heat.

Meets the needs

  • Ideal for rapid heating distributed throughout a room, even when the area to be heated is large, then we do commercial electric heaters with an heat output of 80 kW , which we think are the largest portable electric heater on the UK market to date

3 – Commercial Heaters -Radiation (radiant heating)

 

The radiant heater, also called radiant heating, often looks like a standing fan or cabinet heater. It heats according to the same principle as the lamps used on terraces. It can therefore heat a person very quickly!

Commercial Heaters

Commercial Portable Electric Infrared Heater

 

Operation

  • Uses a very hot element, usually halogen or quartz.
  • The element produces an infrared wave that quickly gives a sensation of warmth in a precise direction.

Benefits

  • Quiet.
  • Sensation of immediate heat, much like the rays of the sun on a winter day; Warms bodies and objects, but not directly air.
  • Allows directing of heat.

 

Meets the needs

  • Ideal for directly heating a person in a room with a high ceiling (because hot air is rising) or in a room where there are drafts. Because of the risk of burns, it is not ideal when there are young children or elderly nearby.

 

Features

Some of the key features of electric heaters are portability, precision temperature monitoring & control and design flexibility

 

Applications

Electric commercial heaters are commonly used throughout industrial and consumer products to heat all types of liquids, gases, vapours, and solids. In consumer products, electric heaters are commonly used for heating water, air and even flooring. Industrial warm air heating applications can utilize much higher wattages and these industrial electrical heaters can be used for applications such as heat treating for pest control , for drying of products etc, as well as standard space heating

 

Advantages of Commercial Electric Heating

  • Low cost in purchase
  • Low installation costs, since no piping necessary
  • No space required for burner or fuel storage
  • No chimney
  • Maintenance costs are eliminated
  • Good solution for temporarily heated rooms or buildings
  • No or little dust swirling, good for allergy sufferers

 

How to calculate how much heat you require , to get your correct commercial heaters or heater

Once you have determined the type of heater for you building you then need to work out which size you require. This can be achieved in the form of a simple heat loss calculation. The most important factors to consider are the dimensions of the building, the length, width and average height. There are a number of online calculators that you can use to work out the heat requirements.  The answer will typically be given in kW (kilowatts) of BTU (British Thermal Units)

Once the appropriate type of commercial heater has been decided and then installed it is advisable to appoint experienced operators at your factory premises so that they can ensure the heater(s) function correctly

Space plays a vital role as far as the correct installation of these apparatuses is concerned. Take measurement of the space where the device or devices are to be installed.

Gas Heaters UK

Gas Heaters UK – Natural gas is a fossil fuel that releases almost no classical pollutants during combustion. It has the lowest carbon content and the highest hydrogen content of all fossil fuels.

In terms of the same energy content, about 25 percent less carbon dioxide (CO2) is produced when burning natural gas than when burning fuel oil. In terms of fine dust, too, natural gas, compared to wood and oil, has a considerable advantage due to the absence of carbon black. One cubic meter of natural gas contains around 10kWh of energy

Natural gas is very affordable, so running a gas heater can be budget friendly. This type of gas is also very clean, so it is good for the environment, which is an additional benefit of using a gas heater.

Most gas heaters are designed to turn off if they fall over or overheat. This safety feature makes gas heaters even safer for your home or office.

These types of heaters provide a very warm heat and are excellent for supplementing an existing heating system. Natural gas is a popular heating option for commercial and industrial locations because it provides a very comfortable heat, making the area feel warm and cozy all winter.

Industrial Space Heater

Industrial Space Heater – Is the heating bill for your plant or warehouse too high? What about cold dock door areas and unbalanced temperatures? Is negative building air pressure a problem? Have you experienced employee complaints and lost productivity from heating or indoor air quality problems? Do you have high maintenance costs for existing heating equipment?

There are only a few common problems that result from choosing the wrong heating system, using obsolete heating/ventilating equipment or simply miscalculating space heaters

Annual space heating costs are a significant part of operating budgets for industrial units, manufacturing plants and large warehouses. Selection and application of the proper space heaters can reduce annual energy costs more than 60% and increase company profits.

What factors determine the best space heating system? Everyone wants a heating and ventilating system that meets their unique requirements at the lowest total cost,wheter it be warm air heating to deliver warm air heating power for various applications such as exhibition halls , or frost protection / temperature protection for building sites, we have a large range of many high performance industrial heaters that can achieve your required results.

Prior to selecting industrial heaters you must first decide the heating/ventilating requirements and understand all the cost factors that determine the true lowest total-cost solution for a specific facility or regular site use.

 

Industrial Space Heater and Space Heating Systems

A gas-fired heating system usually offers the most cost-effective way to heat industrial buildings. Oil-fired and electric heaters are sometimes used for specific space heating applications or when gas is unavailable.

Gas-fired space heating systems are classed as being either direct fired (normally warm air heating ) or indirect fired, and with adjustable thermostatic control and variable heat output, with low heat settings the can provide heat for many applications.

Indirect-fired heating systems use a method of heat transfer, such as a heat exchanger, which lowers overall energy efficiency. A flue is needed to vent the products of combustion outside the building. The inside air is re-circulated with little or no provision for ventilation with outside air. There are two popular types of indirect-fired heating systems.

1.Boiler systems (hot water and steam) have historically been a major source of industrial heat and power. These centralized systems were often used for space heating when energy costs were low, or when steam was a by-product of boilers used for nearby process heating applications.However, industrial boiler heating systems are becoming a thing of the past due to rising energy prices, poor efficiency, uneven heat distribution and high maintenance costs. Many large facilities are now replacing space heating with boilers with efficient gas or oil fired space heaters and use the energy savings to pay for the new equipment.Although condensing boiler technology has improved greatly over the last decade, and “wet systems” are still very popular.

For more information on our range of condensing gas boilers or condensing oil boilers , please click on the links  for further information on our ranges. These “wet heating systems” often use a unit heaters or sometimes referred to as a hot water unit heater or steam unit heater ( if utilizing steam as the heating medium ). These are pictured below , and are basically an industrial radiator with a axial fan behind them that blows out the warm air.

These industrial unit heaters are available with a heating power of up to 400kW, dependant on the medium and temperature feeding these industrial heaters

Hot Water or Steam Unit Heaters

 

 

 

2.Unit heaters are a proven method of heating small, open spaces. Multiple heaters are installed around the perimeter of a building to match heat losses. The benefits of unit heaters include redundancy in case one unit fails, intermittent fan operation that reduces electrical costs and installation on the ceiling or mounted on walls to not take up floor space. Due to a limited air throw, their efficiency can decrease with increased height above the floor.

 

Industrial Space Heater

Standard Gas Unit Heaters – Efficiencies of 91%

For more information on our range of standard gas unit heaters, click here for our standard range or here for our premium range , which has a stainless steel heat exchanger and combustion chamber

The initial installed cost is relatively low for small facilities that only require a few  industrial space heaters but the costs can be higher for large buildings that require multiple heaters. A proportion of heat and energy will escape up the flue. Typical overall efficiencies can vary from 85% to 91%, and these industrial space heaters can be used in a room sealed configuration , meaning that the combustion air that is required is taken from the external air to the building.  This industrial space heater technology has moved on greatly over the last 5 years or so , with the development of  warm air condensing technology , which has resulted in this industrial space heater range achieving efficiencies from 96.6% to 108% , with a pre-mix gas burner with low NOx emissions (class 5) form more information on this range click here.Both the standard or condensing range of  these industrial space heaters ( commonly known as unit heaters ) can be fired by either natural gas or propane gas. There is also an option to have a oil fired suspended industrial heater , please click here for information on this range , which goes from 52kW to 209kW.

 

 

Unit heaters are often used in partnership with make up air heaters in industrial plants or warehouses with constant or variable exhaust loads to provide ventilation.

Industrial Space Heater – Floor Standing Option

If floor space is available, quite a few people opt to have a floor standing industrial heater, as these are often more easily installed , as they are at low level , negating the need for lifting equipment and other associated problems when installing an industrial space heater , pipework etc at high level. They are also easier to service and maintain  at low level , something which needs to be considered when selecting your appropriate industrial space heater. These can be fulled by either gas ( both natural gas or LPG , and even waste oil , bio oil or vegetable oil with one of our multi oil burners ).Here is an example of one looks like , with standard distribution heads –

Warehouse Heaters UK

Warehouse heaters by electric, gas, oil or by heat pumps

Warehouse heaters / heating from Flexiheat UK

Warehouse heaters – It’s essential that when you’re working in a warehouse, it is heated in a sufficient way in order for your business to run correctly and smoothly. Without the correct heating to provide heat, your warehouse or distribution centre wouldn’t be a suitable place for your employees to be working in, or for your customers to browse in an adequate temperature. A warm air heating system tends to be the most popular heating system for warehouse heating, as heated air is the perfect solution or ideal solution for large volumes that you get with warehouse space.

It’s important to use heaters with high energy efficiency that provide good heat distribution and airflows, and a consistent indoor air temperature – All of our industrial heaters are ErP 2021 compliant – which ensures the warmed air is produced with high energy efficiency. These units are a great space heating solution, and provide consistent temperatures, with lower running costs for your HVAC system.

The Warehouse Itself

Deciding on the right space heating system will depend on several factors, such as the layout of the warehouse. Having big doors constantly opening and closing makes it difficult to control the temperature and, consequently, makes it more difficult to keep it at adequate levels. If your warehouse is very big, your heating needs will vary, compared to a smaller warehouse. You might just need heating in specific areas, so it’s important to make sure you’re getting the right heating solution for your warehouse.

Warehouse heaters – their applications

It’s important to ensure that your warehouse is well heated throughout the winter to make sure your employees have a suitable working area.  As the colder days and nights begin to come in, your warehouse will probably require to be warmed up. Some warehouses will need the whole place warming up, whereas others will just require a particular area warming up.

There’s a number of different ways you can heat your warehouse.

Air heating systems as warehouse heaters

The next step in heating your warehouse is choosing a heating system. You need to find the solution that works best for you, so it’s important to note the differences between types of heating, so that you know what you have to work with. Please note direct fired units as not recommended, as they introduce products of combustion, which are poisonous will harm humans in a confined space. Also many insurance companies will not ensure a warehouse or  distribution centre that has direct fired heaters, because of this and also the fire hazard.

Indirect fired air heating systems options include:

Floor standing cabinet heaters

If you prefer, or if your space isn’t at a premium, you might want to check out floor standing indirect fired industrial space heaters, which are available in a number of possible installations: vertically, horizontally or even on the exterior of your warehouse – this is because these heaters have several heat outputs and burners, so their versatility makes them incredibly useful in the workplace. Floor standing heaters can be equipped with various fuel burners –  either oil, natural gas / LPG gas or in some case Multi / Waste Oil burners depending on the type of fuel source is preferred and come with the option of an adjustable thermostat.

Floor standing warehouse heaters are the easiest of all to maintain, as access is granted at any time, without the need of scissor lifts or any scaffolding etc, that you may need when having ceiling suspended heaters to service. Flexiheat have a wide range of high heat outputs floor standing cabinet heaters to suit any warm air heating application. Also ongoing maintenance is easier, as the heaters mounted on the floor space, thus it’s easy to get to the heat exchanger and burner for example.

Suspended Unit Heaters

Perfect if you don’t have a lot of space, as they are out of the way of daily traffic. With plenty to choose from in terms of design, suspended warm air unit heaters are also easy to install and maintain. Suspended heaters come in all different shapes and sizes and can run off either gas, oil or with a wet heating system, whereby a boiler sends heated water to hydronic (or water fed ) unit heaters , which are basically industrial radiators with a axial fan behind them , that blows out the warm air. These unit heaters can also be supplied to work on low pressure steam as well as hot water, should you have steam as a resource available as a heating medium or be fed by heat pumps ( either air source or geothermal) which can be powered by sustainable energy or green energy and produce high energy savings.

They free up valuable floor space and can be wall mounted or mounted in high roofs, blowing the warmed air to the floor level.

Some form of ventilation should be installed in the warehouse to ensure good indoor air quality, we recommend using our commercial mechanical ventilation with heat recovery units – see this webpage – Commercial MVHR – to ventilate with heat recovery for indoor air quality.

Spot heating in a warehouse

There are occasions when only a single spot or work area within a large warehouse or factory needs to be heated. For example:  an admin desk, a person on a production line or a lunch break area. Probably the most common type of spot heating is from an electric infrared radiation / radiant heater, which are portable or mobile , and can used in various locations as and when the heat is required to heat people directly. These radiant infrared heaters use an electric element or a number of these to produce radiant heat directly. Infrared heating or radiant heating is very much suited to heating specific objects or people that are stationary, and take up little floor space. Below is a picture of infrared heaters in use. For more information on this range please see our dedicated webpage portable infrared heaters
