This sturdy 2D diesel air heater from Autoterm Air is perfect for smaller boats due to its compact size (under 7.5 m / we recommend the 4D for larger boats). The digital control panel (including temperature sensor) makes it extremely easy to adjust power levels and temperature. The air heater is certified (e2) and can be installed without registration. The hole dimensions are identical to those of the popular Webasto or Erberspächer heaters, so it is easy to replace without having to drill new holes. Delivery includes an altitude kit and all the components needed for installation.
The heater's cable harness features a gate input for connecting your own remote control or other secondary control unit. You can choose whether the connection is made via ON/OFF switch or pulse. The advantage of the latter means that it is possible to operate the heater with different controllers. For example, you can switch on with a remote control or a push-button and later adjust power levels or even switch off from your bed using the included control element.
In addition, the air heater is equipped with a so-called altitude kit. Thanks to this altitude kit, the heater automatically reduces the quantity of fuel injected depending on the ambient air pressure. This prevents or drastically reduces the likelihood of the combustion chamber from clogging with carbon particulate in the event of a falling air oxygen content.
Maintenance is not normally necessary. However, to prolong service life the combustion chamber must be allowed to get really hot from time to time to burn off any residues. As a rule, running the heater at full power for at least half an hour once every week or every two weeks is enough to allow the combustion chamber to reach full temperature again.
Supplied with new control unit
The new Comfort Control boasts a modern design and numerous functions, such as three adjustable timers, extended heating modes, fan functions and much more. The intelligent thermostat function, for example, automatically switches the heating on when the temperature falls below a set number and similarly turns it off once a set temperature is reached. Multifunctional rotary knob with grippy rubber coating and OLED display. Small installation dimensions, easy to use, stylish design. Temperature sensor included.

Autoterm Air Heater
We purchased this heater to replace our Eberspacher D3L after we found that we could no longer get support or spares. The Autoterm has fantastic reviews, warranty and competitive price. We are extremely satisfied with this product.
Yes, I would recommend this product

We bought to replace the Webasto EVO3900, everything is very easy, same mount, same exhaust, our hot air pipe is already 100mm (the webasto outlet is smaller). The command and programming is more advanced and the configuration is easy. It's a bit noisier, we'll install a muffler. Highly recommended.

I installed the heater to replace my Webasto Airtop3500 which was showing its age. I can't tell any qualitative differences to the three times as expensive systems from the competitors. A few pointers for those interested The mounting base (angle plate) from Webasto did not fit. It is advisable to order a matching base. The connections for exhaust gas, air intake and diesel line, on the other hand, are compatible. The wiring harness is included, must be rerouted, not compatible. The diesel pump is only half as loud as the Webasto one, same installation position. The circulation noises at the vents in the cabin, on the other hand, were somewhat louder. I have therefore installed the appropriate silencer for the flow of warm air directly behind the heater and am now amazed by the silence! You only hear a whisper. The control panel is absolutely great and completely intuitive. The three modes, booster, thermostat and timer are also nice. An external thermostat can also be connected, but in my opinion it is not necessary. All in all a great facility, 5 stars!
