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.

In summer, can the Truma Combi heater heat just water without heating the living area?
Yes.
Simply set the switch to summer mode and select 40 or 60 degrees Celsius water temperature. When the yellow LED on the control panel goes out, the respective water temperature is reached. The heating system heats only water and the circulation fan does not run. Output in summer mode is 2 KW.
Can Truma heaters also be operated while I’m driving?
Yes, heating while driving is possible with Truma Combi and VarioHeat heaters.
With Truma S and Trumatic S heaters, operating the heater while driving is possible only with a cowl top, which must be installed freely in the air flow. Truma recommends the cowl tops T-3 or T-2. Otherwise the flame can blow back and cause damage to the heater.
The cowl top must protrude at least 10 cm above roof attachments, such as roof boxes, ski or luggage racks so that the heater works properly.
For heating while driving, Directive UN ECE R 122 for motor homes and caravans specifies a safety shut-off device. The Truma MonoControl CS gas pressure regulation system fulfils this requirement. Throughout Europe, a type-tested LPG heater may be used while driving (according to Directive UN ECE R 122) if the system includes this regulator with an appropriately configured gas installation. National regulations must be observed.
