Combi D 6

The most efficient combination diesel heater

Features of the new Combi D:
  • Temperature is continuously adjustable using the ergonomic control panel
  • Both the vehicle and the water are heated at the same time in winter operation
  • Only the water is heated in summer operation
  • The unit has a high efficiency level of up to 90 % and low diesel consumption at the same time
  • Diesel burner designed by J. Eberspächer
  • Water mixing is improved by the asymmetrical shape of the 10-litre stainless steel boiler, making the water heat more evenly and rapidly, providing longer showering enjoyment without having to adjust the temperature.
  • The heater can also be operated without filling the boiler
  • 4 warm air connections provide optimum warm air distribution via the quiet, powerful fan
  • The automatic, currentless FrostControl safety and drain valve that is included in the scope of delivery opens at 3 °C and therefore prevents the boiler from freezing
  • The compact design provides a high degree of flexibility when selecting an installation site - virtually the same dimensions as the gas model
  • The temperatures in the installation compartment are lower in comparison to the Trumatic C
  • Water, diesel and warm air duct connections at the side make servicing easier
  • The innovative microprocessor controller provides additional safety


FrostControl safety and drain valve
  • The currentless safety and drain valve automatically empties the boiler via a drain connection if there is a risk of frost (at approx. 3 °C)
  • The drain valve also opens if the pressure is excessively high
  • Draining takes place in stages so that the outlet cannot freeze
  • The drain valve can also be opened manually if required
  • The drain valve cannot be closed until the temperature of the FrostControl is in the frost-free zone again (approx. 7 °C)
  • Currentless operation relieves the strain on the vehicle battery
Truma can supply a heating element as an accessory that heats the FrostControl to approx. 10 °C. The boiler can therefore be filled after a short time, irrespective of the temperature in the installation compartment.

Combi accessories:

The ZUCB time switch can be used to time heating operation up to 7 days in advance.
