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 FrostControl (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 FrostControl 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
