The Truma Combi 4 gas heater has a 4000 W rated thermal output. The Truma Combi 4 water heater is the most lightweight and compact caravan, campervan, motorhome combination heater available. It has unrivalled low power consumption and comes with Frost Control, the current-free safety/drain valve featuring frost monitoring, as standard.
Optimum distribution of warm air through four warm air outlets. The truma Combi 4 boasts short water heating times, but no need to cut your shower short. It has a durable stainless steel water tank.

The Truma Combi 4E has the additional benefit of a 230V 1800W electric element as well, which can be used on it's own or simultaneously with gas.

The Truma Combi 4 and the Truma 4E can both be used to just blow warm air, just heat water or both at the same time!

Additional benefits of the Combi 4

  • Four warm air connections ensure optimum air distribution via a quiet yet powerful fan
  • The temperature can be infinitely adjusted on the ergonomic control panel
  • During winter operation, the vehicle is heated and the water is warmed up at the same time; during summer
  • operation, only the water is warmed up
  • The asymmetrical shape of the 10-litre stainless steel boiler enables the water to be mixed more efficiently - so it
  • warms up more evenly and rapidly - which means you can enjoy longer showers without the need to readjust any
  • settings
  • The heater can be operated even if the boiler hasn't’ been filled
  • The compact design enables a high degree of flexibility when selecting the installation area
  • Water, gas and warm air duct connections at the side make servicing easier
  • The innovative microprocessor control system ensures even more safety

 

Information on Frost Control (safety/drain valve)

  • The current-free safety/drain valve empties the boiler automatically via a drainage socket if there is a risk of frost (i.e. at around 3°C)
  • The drain valve also opens in the event of excess pressure
  • Drainage takes place intermittently, meaning the drainage equipment cannot freeze up
  • If necessary, the drain valve can also be opened manually
  • Only once the temperature of the Frost Control has risen to a level where frost is no longer a risk (i.e. at approx. 7°C) will the drain valve close again
  • Current-free operation discharges the on-board battery
