The Combi D 4 E is structurally identical to the Combi D 4, the only difference being the integrated electric heating elements. The diesel version is equipped with a high-quality burner and therefore reliably heats the vehicle while driving.
The Combi D 4 E heats your vehicle and water at the same time.
The Combi D 4 E is controlled rather easily either via the digital Truma CP Plus (iNet ready) control panel or via the iNet X System.
Integrated electric heating elements reduce the hybrid heating time.

At the camp site, simply switch over to electrical mode and run the heater with 230 V, with no need for the vehicle battery. Depending on the required output, choose between diesel, electric or mixed mode: in milder weather, set the appliance to electrical mode, on colder days to diesel mode and in extremely cold weather use mixed mode – diesel and electrical mode. Through four air outlets, the warm air flows into the vehicle where it is distributed optimally.
The powerful Combi D 4 E heats small and medium-sized vehicles within a short time. The appliance also has a 10-litre water tank, which is heated at the same time when hot water is required. This means that you do not need an additional water heater, which saves space and weight. The Combi heater is also very compact and offers many different installation options.
The Combi D 4 E is controlled and monitored with the digital Truma CP plus (iNet ready) control panel or via the iNet X System.

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.
