More details about Truma Combi 4 E
Truma Combi 4 E combines all the benefits of Combi 4 with those of an electric heater. As opposed to Truma Combi 4, it also has integrated heating elements. This allows you to run the heater at camp sites with the 12V power supply unit without the vehicle battery. Combi 4 E uses very little electricity. The heater runs in gas mode for self-sufficient use, in electrical mode at the camp site and in mixed mode when outside temperatures are low. In summer, Truma Combi 4 E heats just the water without running the space heater.
Like all Combi models, Truma Combi 4 E also combines space and water heating in one appliance. The heater provides comfortable warmth in your vehicle in just a few minutes. It also heats the water that you need for showering, washing dishes or washing your hands. And the best thing about it: you only have to install one appliance in your caravan or motor home. This saves space and weight: as opposed to an S heater, there are no obstacles that you have to walk around in your vehicle.

The heart of the Truma iNet X system and the first step towards a smart camper -

The iNet X System enables you to centrally control your indoor climate, hot water or similar, continually keep an eye on key status indicators and much more.
- One central operating system: control key appliances from different manufacturers and services with one central operating system. So you will always have everything under control.
- Status queries at a glance: real-time status indicators for all appliances and services. So you can always keep an eye on them all.
- Intuitive operation: clear and uniform user interface in the panel with colour touch display and app for intuitive operation. So you will be familiar with the system right away.
- Advanced control via your smartphone: it is possible to control appliances using your own smartphone with the free Truma iNet X App. Meaning you will be smartly connected.
- Future-oriented: add and benefit from further developments by means of updates – even after the system has been installed. So you will always be up-to-date.
- Troubleshooting help: detailed, precise description of the fault including recommendations on how to solve the issue yourself rather than cryptic fault codes. Meaning you are independently and safely on the move.
- Customisable: App interface can be configured according to individual requirements. So everything is geared to your own needs.
The Truma iNet X App is the mobile version of the Truma iNet X Panel. The App can be used to set the hot water from the comfort of your bed or to check the indoor climate while relaxing on your lounger. A Bluetooth connection is currently required for this purpose. The App is required to perform updates to your Truma iNet X (Pro) Panel. This is the only way to extend the system and to benefit from future developments.
