Autoterm Diesel Heater Installation in Cornwall

• The heater unit is supplied with fresh air from outside, which is drawn through an air intake pipe and sent to an internal combustion chamber.

• The received air is mixed with fuel, which is delivered by a metering fuel pump to form the air-fuel mixture.

• The produced mixture is then ignited by a glow plug, which starts the burning process to heat up the heat exchanger.

• Air is drawn from the air inlet with a fan and passed through the heat exchanger radiator fins.

• Finally, the heated air is pushed through a hot air outlet.

Yes. Autoterm diesel heaters are designed for safe, continuous overnight heating in your campervan or motorhome.
