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.

Autoterm heaters are extremely fuel-efficient, using as little as 0.1–0.2 litres of diesel per hour depending on the heat setting.
