New Autotherm diesel heater for our motorboat

The heater works really well. It takes some getting used to, as our old heater only had an on/off function. But you get used to it.

Replacement for Eberspächer

The big challenge was pulling in new cables, but otherwise it works great!

Test phase successful.

The heater was ordered as a replacement for an Ebersbächer 4D. The conversion was very simple; the diesel and exhaust lines, as well as the mounting bracket, could be reused. The air ducts could also be reused after the transitions were installed. After the initial test run, I retrofitted a silencer at the air intake; the noise is now within a tolerable range.

Very good alternative to Eberspächer & Co.

The price was the main reason for looking for alternatives. Eberspächer and Webasto have their parts manufactured in China. The parts are available (identical) without a label – and without CE – even directly in China for even less money. No CE means no insurance (if something happens), so that's not a solution. "E" and "W" claim that other electronics are installed in "their" heaters... yes, yes, yes...
Conclusion: Much quieter than my old Eberspächer D1LC, with two additional silencers (available here: https://www.svb.dedeautoterm-warmluftschalldaempfer-60mm-fuer-luftheizungen-autotherm-2d-planar-2d.html), only a fan noise remains. In terms of heat output, this heater is probably somewhat lower than my previous one – that shouldn't be considered a "negative point," as I don't think you can compare them directly – otherwise, both would have to have exactly the same specifications. All in all – highly recommended.

Diesel warm air heating

The heater works great. Installation was unspectacular. Even the old carrier plate could be used. It is recommended to order the adapters to connect to the old hoses.
Please remember to bring exhaust sealant!

Very good heating.

Very good heater at a reasonable price. Easy installation. Easy replacement for the existing Eberspächer heater. Completely sufficient for a 9m sailing boat.

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.

excellent heating

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.

Class heating

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!

unrivaled good!

I have the heater to replace a new one!!! Webasto heating installed. The heater could be easily mounted on the Webasto fasteners, the exhaust pipe could be connected and the air hoses were also easy to slide on with the adapters available here.
The standard display is great compared to the Webasto standard rotary knob!!!
Note Webasto Air Top Evo 40 always switches to an error without display, which can only be read and reset by a Webasto service station, i. H. the heater must then be removed and taken to the station not suitable for boats.

I replaced the existing Ebersprecher cabin air heater with the Autoterm 2D Ural edition. The delivery was very quick and the packing and installation instructions were clear and easy to follow.

When cruising the Irish coast in damp and cold weather the heater is a great comfort.

Powerful and Affordable

I retrofitted this heater in an old motorhome a few years ago and it convinced me so much in terms of installation, application, quality and price that I am now installing it again in my new motorhome. I can only recommend this product.

Great product at a great price

Installed as a replacement for a gas heater and as a dubbing for a webasto. Super complete material, well packaged, good doc. And half cheaper than the 2 "other brands" and approved, unlike Chinese productions ....
