22GB
Wallas 22GB Diesel 2.2kW Variable Power Forced Air Heater
​
​
Engineered to Minimize Amperage Draw in a Compact Heater
With 2.5 Kw of heating power, the Wallas 22 GB is perfect for smaller boats, camper vans, and trailers, and using only 1 amp at full power, it is an excellent option for sailboats. Improving on the older 22 Dt model, the 22 GB is more powerful and energy-efficient. Double inlet pipes ensure you have oxygen rich fresh air circulating in your boat. Wallas off-grid heaters are pleasant to use as the variable output eliminates system cycling and noise.
While a 22 GB is an entry-level compact 12 V diesel heater, it comes with an easy-to-use thermostatic control panel. Adjusting it to the desired temperature makes sure everyone is comfortable belowdecks.

​
The 22GB diesel heater is unmatched for efficiency, low power draw and reliability, using efficient proportional integral control. Heat sensing for thermostatic operation is taken at the control panel for maximum versatility and ease of installation.
​
The PI panel allows the user to choose simple variable speed ventilation, direct heat with variable output and/or thermostatic control of variable power. This robust control system has been in use for more than a decade with excellent results.
