Gas heater fan TGH 31 E

Let there be heat! Instant heat in larger rooms? – With 30 kW, no sweat!

Inexpensive and effective heating with gas

Mighty heating power to meet the oncoming cold season head-on. One of the best solutions for affordable instant heat is the gas heating device TGH 31 E. Gas is a low-priced energy source – and combined with the inexpensive heater fan TGH 31 E it makes for one of the most economic and simultaneously effective instant heating solutions – even in large rooms.

Ideal for well-ventilated rooms - e.g. on construction sites, in warehouses or workshops

Since connection hose and pressure reducer for connecting the gas cylinder are already included in the TGH 31 E’s scope of delivery, nothing more than a socket and a propane cylinder is required for the heating operation of this powerful gas heating device. The long connection cable increases your flexibility in selecting the installation site.

Once in operation, agreeable warmth begins to spread immediately, seeing as the integrated turbo blower of the TGH 31 E ensures an effective air flow made up of sucked in ambient air and blown out warm air. Even larger rooms can quickly be heated in this manner.

For instance, you can use the powerful 30 kW gas heater fan TGH 31 E for mobile spot heating of well-ventilated construction sites, workshops, storage spaces, garages, stables, greenhouses or else roofed outdoor areas, tents and marquees. Rough operating conditions hardly matter to this heating device, as it comes with a hard-wearing, robust metal construction including space heater in powder-coated corrugated sheet metal design.

With the TGH 31 E you are always on the safe side

With such an enormous heating power in its device class, it goes without saying that safety is also a major priority for the TGH 31 E: For this reason, the standard equipment of this propane heater includes a safety thermostat for overheating protection which automatically interrupts the gas supply in case of overheating while the fan continues to run to ensure the necessary cooling. An additionally integrated temperature sensor serves as flame failure protection and prevents the emission of unburnt gas.

Furthermore, the specially shaped discharge grille of the TGH 31 E prevents direct contact with the flame whilst ensuring an optimally swirled, high-volume current of warm air. Last but not least, the thermally insulated transport handle permits the safe and simple transportation to the next operating site where – thanks to fitted slip-proof rubber feet – the TGH 31 E can be set up safely. Owing to its extremely compact design, the heating device can easily be transported even in the smallest of car boots.

Important information about direct gas heaters

Gas heaters are recommended for use in well-ventilated indoor and covered outdoor areas, where all the heat developed is actually available (100 % output).


In addition to heat, gas fan heaters also emit combustion exhaust gases directly into the room. They are therefore unsuitable for closed rooms without good ventilation if people or animals are present in them.

In addition, approx. 1.6 kg of water vapour is produced per litre of fuel during combustion. Direct gas heaters are therefore not suitable for drying buildings. If gas heaters were used to dry out buildings, the worst that could happen would be that the building would be damper than before!

Gas heaters must also not be used in rooms at risk of fire, e.g. due to the storage of flammable materials.

Good to know: Gas heater fans …

  • are suited for the use in well-ventilated interior spaces and roofed outdoor areas
  • generate a heating capacity of 100%
  • emit combustion waste gases directly into the room along with the heated air
  • are not suitable for the use in closed rooms
  • cannot be used for construction drying, since the combustion generates approx. 1.6 kg of water vapour per litre of fuel
  • must not be used in rooms with a fire hazard due to the storage of flammable substances
