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.

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
