From a listing of a Chinese diesel air heater on eBay for $175.00:

"Name: 8KW 12V Diesel Air Heater Kit
Model: A80946
Specifications
Material: carbon fiber
Color: Black
Size: 390150140mm (1565.5")
Voltage: 12V
Power: 8000W
Fuel: Diesel
Complete combustion rate: 100%
Fuel consumption: 0.1~0.24L
Working temperature: -40C~80C"

Since most out buses are diesel in the first place. It seems like a reasonable choice for heat.
I'll most likely use an 8Kw in the main cabin and a 2Kw or 5Kw in the bedroom.

I just picked up a cheap chinese diesel heater and will be installing it at some point this month. I'll let everyone know how that goes but so far it seems like a winner.

After a lot of research I've determined the chinese ones are basically all the same core unit, and mostly vary based on the included accessories. Different control modules, different vents.. Some kits have a muffler, some have a fuel tank, some have a super basic remote control.

I picked mine up at Amazon and read a lot of reviews of poorly packed units that were shipped from China. I spent a few extra dollars and got one shipped from the US, and it arrived very well packed.

This is the one I bought: https://amzn.to/2Px9u3K

I'll do a full review when it's installed.

Is it a 5 kW or 2 KW. The diesel consumption specification is not clear.
0.1 -0.24 liter / hour? A liter of diesel fuel has an energy content of 10 KWh.
so at full 0.24 liter / hour setting it would be 2.4 KWh input. 60 to 70% efficiency is 1.68 KWh interior heat. rest lost through exhaust.


Curious, later Johan

As am I. These units look to be a good value.

I got the 5KW unit. I've read (but haven't validated) that the 2kw and 5kw units are the same part but differ in programming. Again, this is a rumor I heard and is very likely not true.

The Facebook group on these gives great support.

Make sure to run them near full output very regularly, and occasionally on kero.

Be ready to replace the substandard parts with better quality ones, much more quickly than you would need to with the big 3 makers.

Many are interchangeable.

And **none** of these style units are designed to be used all day every day for long, I think the (better) ones that publish estimated duty cycle rate them at 10,000 hours.

For full-timing in cold conditions a bigger investment up front will pay off long term, examples like Kabola for hydronics, Dickenson Arctic, ITR's Hurricane model. . .

just say'n

I'm looking forward to real user reports. I'm just guessing but if it anything like their hydraulic jacks, where they don't seem to have as many pounds in their tons as we do, I expect that they don't have as many joules in their watts as we do

No, straight knockoffs of the Planar, which knocked off Espar, very similar in effectiveness and fuel consumption as Webasto.

In other words proven in millions of vehicles in cold climates around the world, of that there is no doubt, plenty of evidence over decades.

But these super cheap Chinese ones are **very** likely to break down sooner, there aren't certified dealers to go for for parts or support, you're on your own with design installation and repairs.

And my point about **designed** longevity stands for even the best quality versions.
