Truma Combi comfort plus – 2 -in-1 Functionality

Enjoy twice the comfort with Truma Combi: an RV furnace and water heater in one appliance. This saves space and weight in your travel trailer or motorhome. Truma has integrated a 2.64 gal. (10L) water tank into the system in such a way that the water can be heated by the furnace in the colder months. In warmer weather, you can get hot water for your shower and everyday needs independent of the furnace.  The added 20,400 BTU/h operating level makes the Combi comfort plus powerful enough for larger travel trailers and motorhomes.

In addition to the two-in-one functionality, the Truma Combi comfort plus also has integrated electric heating elements. The heater offers modes for every camping lifestyle: gas mode for self-sufficient “off-the-grid” camping, electric mode for full hook-up at the campsite, and mixed mode for efficient heating in extremely low temperatures.

Truma produces highly-efficient heating and hot water systems for RVs. We have been delighted by the quiet, efficient, and effective performance of the Truma Combi in our Winnebago Travato. In an industry where technology moves slowly, Truma is providing leadership, showing the way to a new generation of innovation.

Truma Combi – The Industry Original

Truma introduced the Combi to the RV industry in 2007, the first RV furnace of its type. Since then, Truma has continued to innovate and evolve this heating technology. Hot air and hot water from one smart appliance provide the comforts of home while out on the road. The water tank is integrated into the furnace, providing hot water while it produces hot air. When the weather is warm, you can use your hot water without running the furnace.

Truma Combi comfort plus:

  • 7,500 BTU/h, 14,300 BTU/h and additional 20,400 BTU/h operating levels
  • Near silent operation
  • Lightweight and space-saving solution
  • Maintains constant temperature throughout the RV
  • Optional electric heating for air and water
  • Water heats up quickly
  • Extremely light and compact, which allows various installation options
  • Very low power consumption
