The Truma Combi 6E is perfect for use in motorhomes, larger campervans and caravans, bringing both water heating and blown-air space heating together in a single compact unit that saves you space and weight, and reduces installation complexity. It has a 6kW max. adjustable heating output that can be powered from liquified gas (propane or butane), electricity or a mix of both, and is quiet and energy efficient for the performance it offers. The multi power source option gives you ultimate flexibility to have heat when you need it, whether you are parked up on site or off grid out in the wilds, and the only other power requirement is a 12 volt DC supply from your leisure battery.

The 4 outlets give you plenty of options to run hot air ducting to suit your installation and the integrated 10L stainless steel tank can operate on water heating only when in 'summer' mode. When operating from gas and electricity in mixed mode, electricity is prioritised to conserve gas, and the water tank can be heated to 60°C in as little as 23 minutes in summer mode.

The Combi 4E is supplied with Truma's iNet X smart control panel with a 4.3" colour touch screen. This next generation panel has a sophisticated user interface coupled with intuitive navigation and step-by-step trouble shooting. It can be used to control other compatible devices and is internet-ready for remote control and monitoring and updates via the iNet X mobile app.

Note: Hot air ducting, air outlet nuts, air outlets and other accessories for Truma combi heaters must be purchased separately - click here to view the full range.
