Wallas 30GB Heater - 3.2kW

wallas 30GB Diesel Heater

Our Wallas 30GB offers increased heating power and more air volume for boat owners. More heating power means you can heat your boat faster, saving power and fuel with shorter heating time. It is also relatively quiet in operation and draws little 12V power.

It has a rugged tough construction which will inevitably pay off in the long run, also it comprises of 100% recycled material frame and burner construction. The burner and frame are made from the highest quality aluminium and stainless steel parts.

Power consumption on boats is widely discussed so with a power usage of between 1.0 – 2.0A this will keep battery usage to a minimum. Additionally, the amount of fuel that this uses is only 0.1 – 0.33 l/h which makes it extremely economical to run from your 12v leisure battery. If you happen to have a 24V system then a simple dropper/converter will be needed which we can supply from our Victron Energy range. A 4mm2 power cable is supplied with the heater as standard which is ideal for where the distance between the heater and the battery is 4m or less. If it’s longer then the cable needs to thicker to ensure there is no voltage drop.


With this new Wallas 30GB model comes more powerful brushless blower motors to give higher efficiency to the heater and better moisture management, important for wet conditions.

Improving on the features of the previous model – 30Dt, the new Wallas 30GB moves more air, improving ventilation and fresh air-flow. There are options on the tubing which take the air from the heater to the outlet grills ranging from a flexible 75mm plastic coated (aluminium lined) tube to an insulated tube which will save energy/heat loss along its route. This saving could be as much as 25w per metre so well worth the investment.

At the end terminal, there are clever grills which are not only adjustable in direction but will also allow you to ‘throttle down’ the flow with this ingenious butterfly valve inbuilt into the grill. This will enable you to ‘balance’ the system ensuring that all areas of the boat get the heat they require.

Also new laminar flow burner and new software, the 30GB is designed to work with today’s road and boat (marine) diesel (EN590) but also with future renewable (HVO 15940) and blended (B10 EN 16734, B20/B30 EN 16709) bio road diesel. This means the 30GB is ready for fuels being developed for the future. The new burner has ultra-low emissions, including very low CO2 and NOx levels. To ensure the highest quality, every single Wallas product is carefully tested before delivery.

The elegant, easy-to-use control panel offers extensive control and monitoring features. The delayed start/stop feature protects the system from accidental starts and stops. The new, LED-illuminated panel can be either flush mounted or bezel mounted while retaining its thermostatic sensing capability. There is even a Wallas Remote Control optional extra which allows you to heat your boat remotely. It’s unbelievably easy to use it with your touch screen mobile phone or tablet and, of course with your computer.

There is also a 2+1 year warranty for all Wallas products to give you that extra peace of mind.
