There are few camper heating system options you might encounter when renting a vehicle in Iceland. The most common one and the one which you will be experiencing in our campervans is the Webasto like heating system. It gained its name from one of its producers. It was first installed mainly in the camping vehicles, but it is getting so popular nowadays, that it is installed even in standard cars. This kind of heating works on a separate battery and is operating independently of the engine. It draws fuel directly from the fuel tank of your vehicle. It consists of using the engine cooling system along with its ventilation system. The air sucked into the unit is essential for the combustion reaction. When it is warmed up, it is passed through the heater exchanger to the interior of the vehicle.
