Hybrid version of the Combi 4/6 with additional electric heating elements for gas, electric or mixed operation.
Forcaravans and motor homes

Combi 4E:

The Combi 4 E combines all the advantages of the Combi 4 with those of an electric heater. In contrast to the Combi 4, it also has integrated electric heating elements. This means that you can operate the heater on the campsite with the 12 V power supply unit completely without an on-board battery. At the same time, the Combi 4 E requires very little power. The heater runs in gas mode for self-sufficient use, in electric mode at the campsite, and in mixed mode when outside temperatures are low. In summer, the Combi 4 E only heats the water without heating.

Like all Combi models, the Combi 4 E combines the functions of heating and water heating in a single device. The heater provides cozy warmth in your vehicle within a few minutes. At the same time, it heats the water you need for showering, rinsing or washing your hands. The clever thing about it is that you only have to install a single device in your caravan or motor home. This saves weight and space: in contrast to an S-heater, the clearance in your vehicle remains fully intact.

You control the temperature in your vehicle continuously on a digital control panel. In combination with the Truma iNet Box, you can switch on your Combi 4 E while you are still on the road using the Truma App via smartphone.

• Two in one: With the Combi 4 E, you heat your vehicle and heat water at the same time.
• Easy to operate: You set the room and water temperature of the Combi 4 E on the Truma CP plus iNet ready digital control panel.
• Flexible to install because it is extremely light and compact
• Warm air from the Combi 4 E is optimally distributed via four air outlets
• Gas, electric and mixed operation possible
• CP plus iNet ready digital control panel: automatic air conditioning in conjunction with a Truma air conditioning system
• Automatic emptying of the water tank at low temperatures thanks to FrostControl

Combi 6E:

The Combi 6 E is a warm air heater with integrated water heater. It differs from the Combi 6 by its integrated electric heating elements. These allow you to run the heater in gas, electric or mixed mode. For stationary use at the campsite, you can operate the Combi heater with the 12 V power pack completely without on-board power.

All you have to do is set your personal comfort temperature on the digital control panel. The powerful blowers of the Combi 6 E do the rest. They distribute the warm air evenly throughout the vehicle via four air outlets. If the boiler is full, the water is heated at the same time. In summer, you can also just heat the water without heating. At temperatures below 3 °C, the FrostControl drain valve opens and automatically drains the boiler. The water is drained intermittently so that the drain does not freeze.

The Combi 6 E is not only powerful and economical, but can also be installed in any vehicle in a space-saving and flexible way.
Two in one: The Combi 6 E is particularly suitable for large vehicles. It combines heating and water heater in one unit.
Easy to operate: you set the room and water temperature of the Combi 6 E on the Truma CP plus iNet ready digital control panel.
