The Eberspächer Airtronic M2 Recreational D4R is designed for installation in rooms where there is not enough space for a 90 mm diameter heat transfer pipe. The D4R has a more powerful hot air fan, which is able to blow heat out of a 75 mm diameter hot air pipe, while avoiding overheating. This makes the D4R heater slightly less fuel efficient compared to the D4L heater (article number 46221).

Compact and quiet boat heater for cold weather.
The Wallas 2000T paraffin heater is designed to replace the older 1800t and 2400t models. With thermostatic temperature control and low power consumption, it is a great choice for smaller boats, even in freezing conditions. The device draws combustion air through a coaxial flue gas jacket pipe and blows the flue gases out. This process improves efficiency, wind resistance and allows for a lower minimum output.
Focusing on low energy consumption, Wallas-Marin designed the 2000 t model to operate on just 0.4-0.7 amps and 0.10-0.20 liters of fuel per hour. It comes with an easy-to-use thermostatic control panel where you can set the desired temperature or operate in manual mode with two power levels: full power at 2000 W or half power at 900 W.

With the new GB burner system, the heater burns current diesels cleanly with lower NOx and CO2 values ??than ever before. At the same time, it is ready for renewable diesel engines that meet the stricter environmental standards of the future. Therefore, when you purchase a Wallas 22 GB heater, you can be sure that it will work with future diesel engines.

In terms of environmental friendliness, the new heaters have more and more parts made from recycled metals and individual parts of the device can be replaced with new ones, which means we save the environment by minimizing unnecessary replacement of additional components.
New fans and air control have also increased the efficiency of the blower, which has also improved the efficiency of the heater. The additional blower provides more power and a shorter drying time for the boat, which saves fuel and electricity. With the renovations, the device is still almost silent, which is important for both a good night's sleep and the comfort of boat neighbors.
Thanks to the uniform outer shell design with the 22D/DT and 30D/DT models, the 22 GB and 30 GB heater is easy to install even in place of an old heater, making it easy to replace it with a new one.
