Diesel Heater (Chinese diesel heater)
So, I’m not sure if this is the correct location to start this topic, but it seemed right.
Thought it would be good to have a central location for ongoing information, questions and experiences.
I bought and installed a “Chinese” diesel heater. Don’t hate me, that is what they are called. Knock-offs of original models. Originals are made by Eberspacher and Webasto and cost a lot more, in the $1200 to $2000 range.
I wanted a supplemental heat source, besides electric or propane, to heat our 42’ Class A with 1 super slide, when we boondock and the temps drop. Propane is good, but not always readily available. Diesel is available just about anywhere. We got stuck at home base, in Missouri, and the winter temps are low. This seemed like a cheap alternative.
Our propane furnace(30,000btu) pulls 10amps when it is running. The diesel heater pulls 10 amps to start, for about 5 minutes, then it goes into run mode, using 1 to 2 amps to run.
Bought my heater off of Amazon, but they are available on eBay and a lot of other sites. Just search for “diesel heater”.
I originally installed it in the basement and plumbed it into the floor heat duct. There wasn’t enough air volume to overcome the duct size/length and put out warm air. So, I now have it installed in my originally planned location.
I managed to fit it under the factory installed Dometic fridge, in the space with the factory furnace. I made my own base plate, to mount it sideways on the floor (acceptable mounting). It draws in its return air from the coach living area at the same source as the furnace. The supply lines are aimed out towards the rear and front of the coach, for now. Planning to get them “plumbed in” in the near future. One of the supply lies is hooked to the flexi-duct that runs down to the wet bay and piping.
The “heater” intake and exhaust both run thru the side wall of the coach. They sell “thru hull” exhaust fittings for a price. I actually drilled a hole and fed the exhaust through it. I wrapped fire-resistant gasket material (that I had) around the pipe where it passes through the wall. Intake is simply stuck through a hole.
Mounted the fuel tank and fuel pump in the basement, on drawer sliders. The tank pulls out for filling.
It was 40 degrees out yesterday. I ran it for about 2 hours and the temp in the rv went up to 75 degrees.
BTW, it came with everything needed to install it. Heater, tank, fuel line, controller, wiring, intake/exhaust, base plate, screws, clamps, etc.
I bought and installed a carbon monoxide detector, as everyone who has these recommended.
The temps here have been in the single digits and the teens for several days (Super Bowl Sunday). We have run the diesel heater the whole time. Propane furnace is on and set, but has not kicked in.
We can go about 26 hours on 7L of diesel. That breaks down to less than 1/10th of a gallon an hour. Yep, these things are metric sizes, centigrade temps, converted Chinese instructions.
