Feedback on Webasto Marine Air Conditioners from Real Boaters – Webasto Marine Air Conditioner Reviews

webasto vs. dometic

We’ve searched the top boating forums – Cruisers Forum, The Hull Truth, Trawler Forum – for feedback on Webasto’s marine A/C units, and found a substantial amount of helpful and insightful info from boaters themselves. If looking for Webasto marine air conditioner reviews, this is an excellent source:


From CruisersForum.com

“I have two units aboard my 45 foot sailboat. The after unit is a Mermaid, which replaced a Mermaid unit, that failed – compressor locked up after seven years. The forward unit is currently a Webasto, which replaced a Dometic which failed at less than three years – the electronics went bad. The Dometic was professionally installed, and I had to change out the thermostat during that three year period twice. The Webasto has been in for two years and runs like a top.

The Mermaid had to go back to the shop for an electrical problem, which they could not duplicate. Rather than argue with m about the problem, they replaced the unit completely. It is noise than the Webasto, but that may be because of differences in the installation.

I outdone definitely consider another Webasto, probably consider another Mermaid and never have another Dometic.”

“I’ve had both my Webasto’s for three years, and for the first two years they ran 24/7 365 days a year keeping the boat dehumidified and warm in Winter.
They have been brilliant, not a flaw. Of course I have had to clean the strainers, but other than that and cleaning the air filters nothing.

I bought them because they were cheap, but I think if you pay attention to the install they are as good as any other AC, and are cheap enough so that in 5 or 10 years when they become problematic, R&R with new.”

“Wow, absolutely love my webastos. I put in 2-16000btu on our boat and have installed 8 more on clients boats. We live aboard our trawler in New Orleans and these puppies run 24/7 for the last five years.”

“The Webasto units are decent. I put a couple 12k units on my bridgedeck to A/C the enclosure 7 years ago and they’ve been flawless. The only compromise is the condensate pans do not appear to be stainless, look like powder coated steel. So far, I’ve seen no rust.”

-Buoy Scout, Admirals Club, Location: VA, Posts: 5,942 – Re: Air Conditioner advice


“We just updated our 16000 Cruise Air unit that was 32 years old to the 16000 Webasto FCF unit and just love it, It was easy to install, runs quieter than the Cruise Air, we love the remote , we also love the dehumidifier mode, we also have a 1600 SMX Cruise Air in our state room and I will be swapping it out for the Webasto unit, also we live aboard full time on a 1980 F40 Trojan Aft Cabin”

“I too just replaced a Marine Air Sytems by Dometic with the Webasto FCF. After considering both, I decided on the Webasto system for two main reasons 1) because of the warranty and 2) the webasto has a lot more aluminum parts that wont corrode. The Dometic system I had was literlly falling apart.”

“Have a couple Webasto units. Nice and quiet, no issues.”

-waybomb, Senior Member, Location: South of the North Pole, Posts: 700 – Re: Marine Heat / AC unit


“I installed three of them {Webasto} on my refit w/o regrets. They are very efficient in amperage consumption, very quiet operation and the cooling capacity is greater than the ones it replaced(cruisair). I would buy them again. I have a mermaid on another boat and I prefer the webasto. Alberto”

“Webasto is very good and has better service than Dometic. They are taking big chunks of the OEM marketshare.”

-Tarbaby, Admirals Club, Location: Ocracoke, NC, Posts: 3,062 – Re: marine a/c units, which one?


“I’ve had 2 Wabasto units on 2 different boats. I’d buy again in a second. I’ve also had Marin Aire, and a 3rd that I can’t recall right now. All performed perfectly”

-LMorgan, Senior Member, Location: DeBary, FL, Posts: 581 – Re: marine a/c units, which one?


From TrawlerForum.com

what is better dometic or webasto?

“I installed a 16k and a 9k on 3/14. They have performed flawlessly. I don’t like the wireless remote control, but it is not needed due to the wired standard control. We are full time liveaboards with flat rate electricity, so they get run alot. Installation was straight forward.”

From BaylinerOwnersClub.com

“Funny… I just had this conversation with a good buddy that owned a boat repair business for many years. He told me that he used to replace Cruisair units with Webasto all the time. In his opinion Webasto units were more reliable and easier, as well as less costly to fix when things went wrong.”

Review on CTM Marine from Trawler Forum

“The CTM was installed in the same space as was the Dometic air handler. The CTM, although it is both the compressor and the air handler, is far quieter than was just the the Dometic air handler, a very pleasant surprise. The CTM seems to be very well made.”

  • Quiet and a powerful source of heat on any vessel
  • Heat output from 3,000 all the way to 18,000+ BTUs
  • Exterior temperature sensor
  • Compact for easy installation
  • 12V / 24V

Below you’ll find what boaters had to say about their Webasto cabin heaters.


From Cruisers Forum

“Webasto diesel heat system. It works great, just like a central forced hot air heating system in your house.”

-Kenomac, cruiser, Location: Pangaea, Posts: 10,856 – Re: Cabin Heaters: Which is Best and Why?


“I’ve had experience with the Espar, Webasto, Force Ten propane, Force Ten Kerosene, Shipmate, Toyoset forced air and a diesel drip style. I found the Webasto to be trouble free, the Espar to be not as trouble free, the Force Ten to put out minimal heat, and the diesel drip (High Seas) to be dirty and very hard to light and get burning well.
I would take the Webasto as #1″

-Cheechako, Senior Cruiser, Location: Skagit City, WA, Posts: 21,580 – Re: Cabin Heaters: Which is Best and Why?


“On my last boat a Bristol 32, I installed the small Webasto. Easy installation in the engine compartment and work flawlessly – I was a liveabaord for 3 years in Philadelphia and then went cruising. Worked great in the marina, at anchor and while sailing. In the 6 years I owned the boat – it was one of the things that was totally problem free.

If I decided to put a heater on my new boat it will be a Webasto again.”

Yacht & Boat World (YBW) Forum

“I have a webasto unit. I can’t remember the model number. It’s always worked a treat.”

-benjenbav, Posts: 12,928, Re: Webasto versus Eberspacher boat heating


“As part of my business I also service both makes.

I am not biased either way when asked to install whatever the client wants, a lot of deals are done at shows and there rock bottom prices.

I can say that the webasto beats eber hands down for ease of servicing, there are 3 main parts to a webasto, where as the eber is full of parts and not as easy to service.”

-volvopaul, Location: midlands, Posts: 7,319, Re: Webasto versus Eberspacher boat heating


“The Webasto by default is designed to recirculate the cabin air and senses the room temp by it’s air intake.

I’ve had Eberspächer, Webasto and Mikuni (in recent time – earlier even a Bacho).

Mikuni was great but not many dealers and fewer accessories (available).

If memory serves me the Mikuni then was more expensive, less smokey and easier on the glowplug (this before burners had more levels, so a lot af on/off action).

They all improved over time, but I prefer Webasto”

-Spi D, Location: Denmark, Posts: 2,254, Re: Webasto versus Eberspacher boat heating


“I have only had one of each and my experience is that Webasto is much better and less trouble (had it 5-6 years now and never been a problem, wasnt new when I got it).

It cuts down in speed variable when it gets warm, the ebspacher just had two noisy settings (had a silencer on the intake too).

I wouldnt mind either on a boat I was buying but if I had the choice when specing new it would be webasto 100%.”
