A combination warm air heater warms the cabin by means of warm air currents that exit through warm air nozzles at the desired points. These can be adjusted individually or turned off completely. This type of heater is inexpensive, durable and requires little maintenance.
The temperature is automatically controlled via a digital control panel.
Combination units produce hot air as well as hot water for the shower, kitchen and sink. They contain a 10 liter hot water tank.
Power is supplied through diesel, from the vehicle's fuel tank, as well as a 12 V/220 V power connection.
