Description
The Truma Combi D4E is the diesel and electric version of the popular Truma Combi 4E, designed for maximum versatility and year-round comfort. It efficiently heats both your living area and domestic water through a compact, integrated system that fits neatly into most motorhomes and campervans.
Equipped with a high-quality diesel burner, the Combi D4E provides reliable heating even while driving. Once you arrive at a campsite, you can easily switch to 230V electric mode to conserve diesel and vehicle battery power.
Depending on the conditions, you can choose between diesel, electric, or mixed mode operation:
- Diesel mode for off-grid or cold conditions
- Electric mode when on mains power
- Mixed mode for maximum heating performance in extreme weather
The unit also features an integrated 10-litre stainless steel water tank, which heats simultaneously during operation, ensuring a consistent hot water supply for showers and washing.
Compact, quiet, and efficient, the Combi D4E is ideal for medium to large motorhomes and offers flexible installation options.
