New, more powerful 2,2Kw heater for environmentally minded customers!
The new Wallas 22GB  Diesel Heater offers increased heating power and greater air volume for boat owners. More heating power means you can heat up your boat faster, saving power and fuel with shorter heating time.

New, more powerful brushless blower motor gives higher efficiency to the heater and better moisture management, important for wet conditions. Improving on the features of the 22Dt, the new 22GB moves more air, improving ventilation and fresh air flow.

With its new laminar flow burner and new software, the 22GB is designed to work with today’s road and boat diesels (EN590) but also with future renewable (HVO 15940) and blended (B10 EN 16734, B20/B30 EN 16709) bio road diesels. This means the 22GB is ready for fuels being developed for the future. The new burner has ultra-low emissions, including very low CO2 and NOx levels.

Construction features more renewable and recycled materials, while improving durability and reliability, featuring stainless steel, high grade aluminum and other corrosion resistant materials.

Outside dimensions, controls and connectivity are the same as old 22Dt models. This means upgrading to the new GB heaters is quick and easy!

The heater box includes: heater, control panel, mounting bracket, 4m of the fuel hose, fuel filter, 4m power cable and the fuse box with fuse.
