Gas Unit Heaters or gas fired unit heater from Flexiheat UK

Output Range – 13 kW to 73 kW

Gas Unit Heaters from Flexiheat UK provide a cost effective and efficient warm air heating solution for industrial and commercial buildings. They have been designed in conjunction with installers, consultants and end users in mind, to provide the perfect solution to your warm air heating needs for commercial or industrial space heating with warm air.

The “FHATX”  unit heater series are suitable for indoor installation and thanks to the closed combustion chamber and atmospheric burner, the “FHATX” gas fired unit heaters achieve up to 95% energy efficiency, and fully comply with the ERP regulations for air heaters that came into force on the 1st January 2021 – known as ErP Lot 21 – 2021, which now requires warm air heaters that provide warmth and comfort for personnel to have a seasonal efficiency of 78% as a minimum, as well as reduced NOx emission levels for gas at 70mg/kWh, to help minimise the impact of global warming .

A gas unit heater is a perfect solution for  Gas Warm Air Heating for warehouse heating, factory heating, or a workshop heater for example. They can be wall mounted , or suspended at high level from the ceiling in high ceilings buildings, saving valuable floor space, that can be put to better use in any industrial and commercial large spaces.

With our range of gas fired highly energy efficient industrial suspended heaters being suited to both industrial and commercial installation as the installed cost is very low on these units. Installation time is also very quick and cost effective too for this efficient heating system for a commercial or industrial space.

In the summer period , you can use this gas unit heater range in a ventilation mode. This ventilation only mode, will move the air around the location, and help with lowering humidity levels to ensure comfort levels.

Gas Fired Unit Heaters – The Range

This gas unit heater range have efficiency ratings that fulfil the UK Part L Building Regulations’ minimum heater efficiency performance requirements, as well as being ErP 2021 approved.

The combustion chamber and heat exchanger combination are specifically designed and manufactured to combine thermal efficiency with long performance service life in a compact design.

We can offer the following comprehensive range of suspended gas unit heaters –

The FHATX-H Range – which comprises of 5 models with Axial fan for horizontal blowing. These models offer outputs ranging from 13 kW to 73 kW

The FHATX-C Range – which comprises of 5 models with a centrifugal fan option for ducted applications. These models offer outputs ranging from 13 kW to 73 kW. Ducted applications allow you to place these industrial suspended heaters wherever you require, with the centrifugal fan pushing the heated air to the desired location via a duct system.

The FHATX-V Range – which comprises of 5 models with high efficiency and are suitable for vertical mounting applications -i.e. blowing warm air downwards. These models offer outputs ranging from 13kw to 73 kW and are ideal for commercial applications.

All units can be used in a room sealed configuration, with the air for combustion being taken from the exterior of the building being heated.

This range of gas fired heaters are easy to maintain, as the heater function controls, gas valve, and burner assembly are all accessible through a full-width door on these warm air unit heater range

Gas Fired Heaters – Customer Benefits

  • Thermal efficiency of 92% on high fire or 95 % on low fire
  • Efficient heat exchanger, long life service
  • Maximum use of combustion energy
  • Rapid and easy installation
  • Efficient air distribution
  • Safe use
  • Low height of the suspended gas device, useful for buildings with low ceilings and large areas.

The standard range are an axial fan ,with two stage burners in mains natural gas or LPG .

We also do a gas fired condensing unit heater range, which has higher efficiencies of up to 106%, as a condensing unit heater recovers some of the latent heat from the combustion gases thus a stainless steel heat exchanger along with a stainless steel combustion chamber are used.

This means that condensate produced when a condensing unit heater is in operation, which has to be drained away from the unit and go into a drain which adds to the installation time and cost of a condensing unit heater.

We have a dedicated webpage on these high efficiency gas fired unit heater range here – condensing unit heater

 

Mounting Options

This range of gas heaters have three mounting options:

• Swivelling console

For mounting on walls, consisting of 2 plates and 2 lateral supports. The heater can be placed on top of the console or suspended from it. The device can be swivelled horizontally through 180° for placement in corners of the building . This bracket is available for all models except the 75 & 95 models

 

Wall console bracket

• Wall Mounting Brackets 

For wall mounting, consisting of two steel brackets. The heater can be placed on top of both supports and can also be suspended from them. Suitable for all heater models.

 

Wall Bracket Set
• Threaded tapping’s

For suspension from the ceiling. On top of each heater are M8 fastening points in which threaded rod , or threaded eyelets can be inserted. Thus you can suspend the units from chain or rod depending on your preference.

Room Sealed Unit Heaters – Versatile Flue Installations

The balanced flue terminal provides both the combustion air inlet and flue outlet from a single building penetration. The terminals are ordered separately from the heaters to suit either a wall outlet or roof outlet. Additional flue and combustion air pipes may be added, up to a maximum of six metres of flue pipe, plus six metres of combustion air pipe. (This reduces by one metre for every 90° bend fitted).
To comply with CE approvals, balanced flue appliances must be used with the manufacturer’s balanced flue system.
The units are also certified for fan assisted flue installations, where the fresh air for combustion is to be drawn from within the heated space; an alternative wall or roof terminal is required for this application.
