GB SERIES | Air Heater
1500 – 3000 W
5,100 – 10,200 BTU
Powerful Design Punch Offers Increased Heating Power and Air Volume
Wallas 30 GB has become the most popular diesel air heater in the Wallas range of products due to its low energy consumption and optimal heating power for small to mid-size boats. In addition to efficiency, the variable output eliminates disturbing starts and stops allowing you to rest and relax. Boaters also appreciate the laminar combustion for clean dry heat, which keeps the windows fog-free.
Improving on the features of the older 30 Dt model, 30 GB moves more air with better ventilation. With double inlet pipes, this 3.0 kW heater is engineered to ensure you will always have fresh airflow in the cabin. The simple-to-use thermostatic control panel maintains a steady target temperature for everyone’s comfort. 30 GB’s outside dimensions, controls, and connectivity are the same as in the older 30 Dt and similar to 30 D models, which makes it an easy upgrade to a newer more energy-efficient heater.
Two Inlets and Outlets Improve Airflow and Efficiency
Two inlets take fresh air from outside and recirculate heated air in the cabin. This improves efficiency and ensures oxygen rich air in the cabin.
Two outlets reduce air drag and keep the sound level low. They also reduce power consumption and facilitate smooth distribution of heated air throughout the cabin. The bigger the cross-sectional area of the ducts are, the less it reducts the airflow and does not require more power from the ventilation fan.
Variable output eliminates disturbing system cycling and reduces noise.
Fully enclosed laminar burning process does not leak odors into the cabin and dries the indoor air.
Brushless blower motors have a very long life-cycle, supporting reliably long service intervals.
Updated software optimizes fuel and electricity consumption
Calibrated to burn renewable fossil free diesel (e.g. HVO) in addition to traditional road and boat diesel
Larger burner burns fuel slower resulting in ultra low NOX emissions
Extensively tested with Neste
Improved burner efficiency for more power
The Greenboost burner burns renewable fossil-free diesel cleanly and energy-efficiently
Two inlets and outlets improve fresh airflow and efficiency
Combustion air is taken from outside the boat through the outer coaxial pipe
Exhaust gas is safely expelled outside through the inner coaxial pipe keeping the indoor air clean and odourless
Fully enclosed laminar burning process ensures a quiet sound level and dries the indoor air
Variable output eliminates system cycling and reduces noise
Brushless blower motor has a longer life-cycle and requires less frequent servicing
Feeding fuel directly from the main tank of the vessel saves space and eliminates the need for a separate tank
Durable Finnish design and manufacturing keep your heater running through tough weather conditions
Three second press-and-hold upon starting the unit improves safety for families with children
Enjoy smooth temperature in cabin
Ensure everyone’s safety with a heater that has low temperature on unit and exhaust pipe
Keep interior upholstery fresh with dry heat from the laminar combustion
Have better comfort control with an easy-to-use thermostatic control panel

Recommended builds should be used as general guidelines. The needed heat output is based largely on the material (wood, fiberglass, aluminum etc.) and structure of the boat. Always discuss this with a Wallas distributor, before making your purchase.
Technical values are measured in a reference measurement wall, which is constructed to respond to a typical boat installation. Values have been measured with maximum length of ducting, exhaust pipe, fuel line, and power cord. Figures allow for 10% reserve – yours may vary.
Wallas diesel heaters are designed to run with standard road and boat diesel, as well as renewable fossil free diesel. Check with your distributor for further details on best options for your needs.
