  • How does the Truma S heater work?

    The heater is supplied with gas via a special connection (1). It is ignited by a battery-operated auto ignitor (2) in the burner (3). You can see through the inspection glass (4) if the gas has ignited. External air is sucked into the heater through an inlet (5) and is heated by the naked flame in the burner (3). The hot air flows through the S-shaped heat exchanger (6) and exits the system to the atmosphere together with the combustion air through the exhaust duct (7) and the roof cowl (8). This process is 100% safe thanks to the completely enclosed system and the thermoelectric safety pilot. The heat exchanger (6) heats the direct ambient air in the heater housing. It exits through the holes in the cover into the living area and, if necessary, is distributed in the caravan by the fan (14).

    The temperature of the heater is infinitely adjustable with the manual knob on the control panel (9). This activates the safety pilot valve (12) via the control panel rod (11). When the required room temperature is reached, a thermostat sensor (13) regulates the gas supply to the burner and reduces it accordingly. The fan is controlled via a second control knob (10).

    The Ultraheat additional electric heater (15) is the perfect supplement for everyone who wants additional electric heat and to get the RV nice and warm quickly independently of the gas supply. It heats very quickly and uses the fan of the S heater to distribute the warm air efficiently throughout the caravan.

  • Can Truma heaters also be operated while I’m driving?

    Yes, heating while driving is possible with Truma Combi and VarioHeat heaters.

    With Truma S and Trumatic S heaters, operating the heater while driving is possible only with a cowl top, which must be installed freely in the air flow. Truma recommends the cowl tops T-3 or T-2. Otherwise the flame can blow back and cause damage to the heater.

    The cowl top must protrude at least 10 cm above roof attachments, such as roof boxes, ski or luggage racks so that the heater works properly.

    For heating while driving, Directive UN ECE R 122 for motor homes and caravans specifies a safety shut-off device. The Truma MonoControl CS gas pressure regulation system fulfils this requirement. Throughout Europe, a type-tested LPG heater may be used while driving (according to Directive UN ECE R 122) if the system includes this regulator with an appropriately configured gas installation. National regulations must be observed.

  • May I install a Truma heater in the awning?


    Our current appliances are approved only for recreational vehicles. Therefore, installation in an awning is unfortunately not allowed.

    But you can retrofit your Truma heater with an awning warmer. This directs the warm air from the existing caravan heater directly into the awning.

    Heaters that are already installed are protected by a grandfather clause.
