Truma Combi D4E Diesel & Electric Blown Air & Water Heater with iNet X Control Panel
The Combi D 4 E is nearly identical to the Combi D 4, with the key difference being the inclusion of integrated electric heating elements. Designed for versatility, this diesel-powered heater ensures reliable warmth while driving, thanks to its high-quality burner.
At a campsite, simply switch to electric mode and run the heater on 230V, eliminating the need for your vehicle battery. Depending on your heating needs, you can choose between:
- Diesel mode for colder days
- Electric mode for milder weather
- Mixed mode (diesel & electric) for extremely cold conditions
With four air outlets, the Combi D 4 E distributes warm air efficiently throughout the vehicle.
Compact & Efficient Heating
Ideal for small to medium-sized vehicles, the Combi D 4 E heats up quickly and features a 10-litre water tank, which warms simultaneously when hot water is required—eliminating the need for an additional water heater. Its compact design allows for flexible installation while saving space and weight.
Smart Control & Monitoring
Control and monitor the heater effortlessly via the advanced iNet X System.
