How does an air heater work?

  1. The heater unit is supplied with fresh air from outside or a well-ventilated room, which is drawn through an air intake pipe and sent to an internal combustion chamber.
  2. The received air is mixed with fuel, which is delivered by a metering fuel pump to form the air-fuel mixture.
  3. The produced mixture is then ignited by a glow plug, which starts the burning process to heat up the heat exchanger.
  4. 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.
