    More Details about Truma Combi comfort plus

    All you have to do is set your preferred temperature on the digital control panel and let the powerful fans of the Truma Combi comfort plus do the rest. They distribute warm air evenly throughout the vehicle through the four air outlets. If the water tank is filled, water is heated at the same time. In summer, you can heat just the water without using the space heater.

    Combi comfort plus is not only powerful and economical, it can also be installed flexibly in any vehicle and requires little space.

    • Lightweight and compact, allowing various installation options
    • In hot water mode, water can be heated independently of the space heater

      The furnace is switched on and the required temperature for heating and warm water is set on the Truma Combi LCD control panel (1). The gas supply to the furnace is controlled by the solenoid valve (3). The necessary combustion air flows through the outer pipe of the combined inlet for combustion air/outlet for exhaust (4) into the furnace and is transported into the gas burner (6) with the help of the combustion air motor (5). The gas burner ignites the gas-air mixture in the combustion chamber (8).

      The hot exhaust gases are deflected at the end of the combustion chamber on the baffle plate of the flame tube (9) and flow back between the burner's flame tube and the inner wall of the heat exchanger. They leave the furnace through the exhaust outlet (4).

      The circulation air fan (10) feeds the air to be heated into the device. The air flows along the heat exchanger (11) ribs, which ensure optimum heat transfer with their large transfer surface. Additional electric heating elements (12) are situated in the heat exchanger. Water and/or air can be alternatively or additionally heated by them. The warm air is then distributed in the vehicle via four warm air outlets (13). The fresh water is located in the outer stainless steel water container (14). It is heated by heat transfer from the heat exchanger (11).
