Truma Combi 4 Diesel CP Plus iNet X System heating for motorhomes and campers.

Combi D 4 (Next generation)
Heating and hot water for small and medium-sized vehicles
ombi D 4 heats water in a single device. A ten-liter water tank is integrated into the heating: In winter, you simply heat the water with it; In summer, the water is heated independently of the heating. Warm air flows in through four air vents.

Saving battery and diesel consumption thanks to more efficient combustion.
2 in 1: heat the room and water
More independent: heats at any altitude thanks to the integrated pressure sensor

Individual, energy efficient and self-sufficient: Combi D 4
Combi D 4 heats water in a single device. A ten-liter water tank is integrated into the heating: In winter, you simply heat the water with it; In summer, the water is heated independently of the heating. Warm air flows into the interior through four air vents, for a pleasant indoor climate. At the same time, Combi heating is particularly economical.

The pressure sensor integrated directly into the electronics automatically regulates the combustion air supply. For greater flexibility, Combi D 4 is also available in version E with additionally integrated electric heating rods.
