Truma D6E Gen 2 Combi Boiler with iNet X - Diesel & 240v Electric Model 33516-78

The powerful Combi D6E 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 is also very compact and offers many different installation options.

The Combi D6E is controlled and monitored with the digital Truma iNet X System.

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 heating can also be operated with an empty water tank

- Optimum warm air distribution via four air outlets

- 10-litre stainless steel water tank
