Truma Combi D4E Diesel blown air and water heater

The Truma Combi series is the first choice for heating water and living areas in your campervan, motorhome, or caravan. These combination heaters are known for their reliability, energy efficiency, quiet operation, and compact design, delivering impressive heating performance.

Ideal for both summer and winter adventures in your caravan, campervan or motorhome, the Combi D4E features all the advantages of the standard Truma Combi range but is fueled by diesel from your vehicle tank, along with an electric element. This makes it a reliable heating solution, ensuring you can easily find fuel even on extended trips. This also saves the cost of  adding a gas system to your build.

Equipped with a built-in 10-litre stainless steel water tank, the Truma D4E has built-in independent control, enabling you to heat water only during the summer or both hot water and a cosy living area during the colder months.

Efficient Air Space Heating from the Truma Combi D4E

With four hot air outlets, the Truma Combi D4E effectively warms the living space of your motorhome, caravan, or campervan. The digital Truma iNet X control panel offers convenient straightforward control over the heater’s functions whenever needed.

Flexible Operation

This versatile kit can run on either 230V electric mains power, diesel fuel, or a combination of both. The Truma Combi D4E heater model ensures you have hot water and a cosy living area, whether you’re at a powered campsite or off-grid in nature. For quick heating when you’re set up at a site, you can use both electric and diesel sources together for faster results.
