Individual, energy-efficient, self-sufficient – the Combi D 4

The Combi D 4 also combines space and water heating in one appliance. A 10-litre water tank is integrated into the system: the water is heated at the same time in winter, in the summer it is possible to heat up the water independently of the heater. The warm air flows into the vehicle’s interior through four air outlets to ensure a pleasant indoor climate. The Combi heater works very economically here. 

The integrated pressure sensor on the electronics automatically controls the combustion air infeed. The Combi D 4 even in the electric version is available with additional integrated electric heating elements.
