How an Eberspächer air heater works:

The heater is supplied with fuel directly from the boat's tank. The fan of the heater draw fresh air in and blows the heated air into the cabin. In summer the fan can be used for fresh air supply only without heating. They draw in cool room or outside air, heat this up and then deliver it to the interior of the vehicle.

Air heaters are an excellent solution for commercial vehicles of every type. They can be installed just as well in the cab as in the luggage compartment or under the floor.

Scientists have found that one feels best at an ambient temperature of 22°C and a relative humidity of 60%. In addition to this comfort range according to DIN 1946, a minimum fresh air rate of 20 m3 (non-smokers) or 20 m3 (smokers) per person and hour is required. Optimum wellbeing on board is guaranteed with Eberspächer air heaters. Our sophisticated heaters delivery exactly the right amount of heat. And solutions such as the D5L C bring it to an impressive 233 m3 of air per hour.
