The Truma Combi 4E is a versatile, energy-efficient heating solution designed for caravans and motorhomes, combining powerful space heating with a 10-litre water boiler in one compact unit.

Unlike the standard Combi 4, the 4E includes integrated electric heating elements, giving you the freedom to choose between gas, electric, or mixed mode depending on your setup and the weather.

When travelling, the gas burner provides reliable heating on the move. At the campsite, switch to the 230V electric supply to save on gas, or use both together for fast, efficient heating in colder conditions. In summer, the appliance can run in hot water mode only, quickly heating water for showers, washing up, or everyday use without warming the living space.

Lightweight and compact, the Combi 4E offers flexible installation and distributes warm air evenly through four outlets, ensuring comfort throughout your vehicle. Safety and convenience come built-in, with automatic frost protection and the easy-to-use Truma CP Plus digital control panel (iNet ready).

The Combi 4E kit includes the LPG and 230V electric heater unit, CP Plus control panel, 6m cable, water fittings, fuel pump, and wall cowl. Below is a brief video from Truma with more information! Underneath the video are also some key specs for the product.

Please note: as standard, this product comes with a black cowl. You can find an optional white cowl here.
