Truma Combi G – Gasoline-powered 2-in-1 Comfort

The Truma Combi G is Truma’s first gasoline-powered system. The newest evolution of Truma’s signature 2-in-1 system is a single-fuel solution that delivers hot air and hot water from one smart appliance. This saves space and weight in your RV by eliminating the need for bulky propane tanks to fuel your furnace and water heater.

Like its propane predecessor, Combi G has integrated a 2.6-gallon (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 Combi G features five operating levels to achieve the desired temperature in the RV more efficiently. With automatic altitude adjustment, the system will perform efficiently at high altitudes without any additional preparation for those spontaneous weekends in the mountains.

I have used the heating function almost every night. So thankful It's been reliable, and I no longer have to worry about propane as I would have been on my fourth tank by now.

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 G comfort:

  • Five operating levels: 6,800 BTU/h, 10,200 BTU/h, 13,650 BTU/h, 17,060 BTU/h, and 20,470 BTU/h
  • Lightweight and space-saving solution
  • Maintains constant temperature throughout the RV with only three air ducts
  • Eliminates the need for bulky propane tanks
  • Water heats up quickly
  • Extremely light and compact, which allows various installation options
  • Very low power consumption
