The Truma Combi D 4E is a powerful and versatile heater designed for small to medium-sized campervans, caravans and motorhomes.

Combining diesel heating with integrated electric elements, it delivers flexible performance whether you’re on the road, off-grid, or connected to mains hook-up at a campsite.

In diesel mode, the Combi D4E uses an efficient, high-quality burner to heat your vehicle even while driving. At the campsite, you can switch to electric mode to run on 230V power without drawing on your vehicle’s battery. For very cold conditions, mixed mode combines both diesel and electric for maximum heating output. Warm air is distributed evenly through four outlets, ensuring fast and comfortable heating throughout your living space.

Alongside space heating, the Combi D4E features a 10-litre stainless steel water tank that heats simultaneously, supplying hot water for showers, washing up, and daily use. Compact and lightweight, it saves valuable space while eliminating the need for a separate water heater.

Control is simple with the included Truma CP Plus iNet ready panel or via the iNet X system, with the option of automatic climate control when paired with a Truma air conditioner. The kit includes the Combi D4E unit, CP Plus panel, exhaust ducting, black cowl, JG water fittings and a 6m data cable. Ducting and outlets are sold separately, allowing you to customise installation to your vehicle.
