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.

Great value for money
We have a Malö 33 Bj. 89 and have renewed the original Eberspächer heater including the thermostat. Everything fits perfectly and works perfectly

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.

Leistungsstark und Preisgünstig
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.

Super produit à très bon prix
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 ....

Schnell und gut
The use in the large motorhome is optimal and brings a quick heat distribution, thanks to the integrated and adjustable fan with heat output regulation. The self-installation is done quickly with a little manual skill once you have located the appropriate installation location in the vehicle. Depending on how it is placed in the vehicle, the fan noise can be a bit annoying in the high power levels. The minimal fuel consumption does not affect the travel vehicle in any way.

Good and cheap
The heater has only been installed for two months, but so far it is doing an excellent job. The exhaust pipe included in the set is rather short. The suction through the diesel feed pump is also a little cumbersome.

All in all, I am very satisfied and can recommend the product.

Good heater
Contrary to other information, the Autoterm does not fit on the Webasto mount. Definitely not on the old Air Top 32 that we replaced.
Otherwise, I would have been happy to hear that the supplied cable for the control unit, at 1.8m, is probably far too short for any boat. Would have saved me an extra lap.

Qualität mit kleinen Macken
The product description states that the Autoterm fits well as a replacement device for Webasto. Unfortunately, there is no information about which Webasto model. I had a Webasto HL 32 and it has completely different connections and fixings. The display of the control unit is unfortunately a little crooked in its housing. The fan makes a humming noise. Everything is still bearable but a little annoying. The price-performance ratio is still very good.

Heating works perfectly!
I don't like the Comfort Control control panel!
Smaller than shown in the pictures. In my opinion, the electronics are too playful and confusing! Can hardly be operated by spouses or fellow sailors!
The simple selector switch was understandable to everyone on the old Eberspächer heater!
Ventilation or heating from levels 1 to 6, that's it and understandable for everyone!

Leider ist die Servicequalität im Moment deutlich zu schlecht.
The product could not yet be used due to the lack of a control unit.

Unreliable from the start
A seemingly good kit, well made parts etc. however after the first use of about 1 hour, the heater produces vast amounts of smoke and flames out. Restarting is now not possible. Unable to get a response from Planar UK for technical help. I would avoid this product

made in Russia
I don't know this material but I am surprised that SVB sells products made in Russia

Bonjour Monsieur,

Au début du conflit en Ukraine, Autoterm a tout de suite réagi et a déplacé sa production à Riga, en Lettonie. Ce produit est alors dorénavant made in UE !

Diesel hot air heater 4D
I bought and installed the heater.
Unfortunately, the cable for the control unit is missing. I can't start the heater without a cable.
After calling several times that the cable is missing, unfortunately still nothing happened.
That was 5 weeks ago. I have never experienced such bad service.
