The Truma Combi 4E is a highly versatile heater that combines warm air and hot water in one compact, lightweight unit.

Designed for campervans, caravans and motorhomes, it delivers reliable heating through gas, electric or mixed operation, giving you complete flexibility whether touring or staying at a campsite with mains hook-up.

Its powerful fans distribute warm air evenly through four outlets, ensuring fast and consistent comfort throughout your vehicle. At the same time, the integrated 10-litre stainless steel water tank provides hot water for washing and showering. In summer mode, you can heat water independently without running the space heater – saving energy while keeping things practical.

The Combi 4E is quiet, economical and space-efficient, making it an excellent choice for compact installations. It also offers compatibility with automatic climate control when paired with a Truma air conditioner, ensuring effortless year-round comfort. The kit includes the iNet digital control panel, black cowl, Combi 4E unit and JG water fittings, so you have everything needed for installation.

Please note that ductings and outlets for this product are sold separately.
