 The 2.2 kW diesel heater has extremely low power consumption – only 0.9 A at maximum power.

Despite the low power consumption, the air volume capacity is better than in comparable 2 kW heaters on the market. Better air volume ensures good drying effect and heat distribution. 

The effective output for the amount of amps consumed is the best in its class. Therefore, the heater is ideal for sailing boats budgeting power.

Thanks to the laminar burn process and silent brushless blower motors, the sound level is equal to the level of a whisper in a library. Furthermore, there is no combustion noise, so the boat next to yours can also enjoy the silence.

22 Dt can be installed into an engine compartment. With the help of two air inlets you can get fresh air and strengthen the heating effect. This results from taking both fresh air from outside and cabin air from inside to circulate the heat.

Wallas Remote Control allows you to heat up your boat remotely.
