Bring the heat to your campervan with the Truma 4DE diesel heater combi boiler. This combination unit is powered by diesel so it can quickly heat both your water and circulate hot air around your van.

This unit is structurally identical to the Combi 4 D. The Truma 4DE diesel heater differs in that it incorporates integrated electric heating elements, meaning it has maximum efficiency.

Depending on the required output, choose from diesel, electric or mixed mode. When running on diesel, the 4 D E is fitted with a high quality burner in order to reliably heat your vehicle quickly. On a campsite, simply switch over to electrical mode and run the heater with 230v meaning you can run the unit without using power from your vehicle battery.

We supply the Combi 4 D E diesel with the Truma iNet X control system, which is the latest generation tech from Truma. Control your unit via the easy to use, 4.3″ colour touchscreen or on the move from your mobile device.

The iNet X system will always be up to date as it can receive extensions and updates. It is service integrated, offering instructions rather than cryptic fault codes so you can keep everything running whilst out on the road.
