one commenter under questions says Eberspacher parts are same.

The skoolie crowd are deep into these various chinese knock-off heaters.

I would back it up with a quality CO and smoke detector, and have a positive fuel shut off positioned so it is accessible with the unit on fire...

You can buy quite a few of them for the same price for an Eberspacher or Webasto bunk heater.

There isn't much mention of them in the commercial circles, i wonder about their longer term reliability in daily heavy use.

Peeps don't get online to report they froze their a$$ off when it failed, and then spend their internet money on a replacement...

There's got to be something different between  $1500 big name, and a $200 knock-off, than just profit...

Happy coaching!

I took interest in these some 23 months ago wondering the same things. According to the good reviews on U-tube they have held up pretty good. one video blogger had his in continual use for over 14 months, now that is not bad. Agreed on the fuel shut off with the obligatory CO detectors and such. the 5Kw unit prices were all over the place a few years ago but averaged $139.00, 8Kw's were @ $159.00+. There are units that have a water heating loop also . I almost ordered a pair of the 5Kw's last week but our L.E.D. headlights were first on the todo list, next month maybe.

Overall, most of those are reliable as long as you use a very tiny I.D. hose. Preferably a genuine Webasto fuel line. Pumps must be at a 45º angle and wiring should be heavy gauge with at least a #10.

FB has a specific group called Chinese Diesel vehicle air heaters - troubleshooting, repair and parts.

You will learn a shite ton on that site.

Just finished a 1600 mile road trip over 8 days in cold weather for the first time with a Chinese diesel air heater. In my words: they're worth their weight in diamonds! Never had to run our larger LP furnace & stayed toasty warm with a measly 8000btu Chinese diesel air heater. The main difference is they don't cycle like a heater with a thermostat. They run constant but do regulate how much fuel (heat) they produce paralleled with fan speed. At as low as $100 per 8000btu unit - they are way more than a lot cheaper than the name brands. Don't know their longevity yet. But know people that have been running them for over several years w/o issue. Heck at that insanely low price buy a few and have replacements on hand. They are efficient misers for fuel and 12vdc. Burned through less than 5 gal of diesel in that time span. The water heating loops are not available in the US (yet) but are being sold in the UK or on Alibaba.
That's my story & I'm stickin' to it!

I was reading all the answered questions where an owner stated the Eberspacher parts would interchange.
Considering adding one to Coach for supplemental to a propane furnace. I'll check out the Facebook site and Utube videos. Thanks.

The main maintenance on the unit is periodic cleaning as it has a tendency to soot up over time. It is a good practice after a long low heat & low fan run to run it on high for 5 min. to burn any soot that accumulates from low slow burn. I like the performance of ours so much I am in the process of purchasing two more identical units. Installation of another unit & one for parts @ $120 each! Too cheap not to play with...

[buswarrior]

The Eberspacher automatically runs hard at the start, and throttles back according to the controller's temp input after a few minutes.

X2, every one of the oil burning devices needs to be opened up and cleaned, and whatever periodic maintenance is recommended, just do it. Fresh nozzle, spark adjustment, flame sensor cleaned, whatever...

These things don't crap out from lack of maintenance at a convenient time... and they will try to tell you, poor starting, smoke, noises... if you pay attention...

LOL they sure stink when they do go bad I threw 2 of those a way last week a owner removed his were Russian made but identical  ,they are cheap you can buy 3 for the price of a fuel pump on a Webasto,you cannot get parts for those just remember they are throw a ways units   

[chessie4905]

went to the Facebook site and read some posts. WOW! lots of info, lots of help with any issues, lots of actual users. Has me sold on them. Have to figure on how to do clean installs and do it safely. Would prefer 24 volt version so will do a little more research. Don't  want to wait too long to get them. Guarantee these things will jump significantly in price, as China is experiencing inflation too.

Check the military surplus John they use Telex 24v made in the US I have 5 that goes with my military kitchen they are neat they have the warm up mode and make a lot more BTU's. Have you saw the made in China knock offs for the Fantastic Fans $104.00 vs $400.00     

[chessie4905]

wonder if they make a Webasto knock off one?
One poster commented they make a water heating loop air type, but only sold in eu at present.

Put one in our MCI7 last year works better than the propane furnace

5 to 7000 btu's  from those units won't touch the 30,000 btu from a propane forced air furnace lets get real here I been around both you will freeze your @$# off in 20 degrees weather with 7000 btu's

Ed where is yours mounted as well as what area of the coach  you have the air distributed? I know that this would be a consideration if it is being used as a Point of use only unit vs trying to heat the entire coach. looking back now the units that include an H2o loop were a EU available item.
