Diesel Heater???

Post by MiriamN » Sun Nov 10, 2019 7:07 pm

Does any one know if it's possible to remove the existing furnace and replace with one of these Wabasto or Chinese knockoff diesel furnaces, and install a diesel source? If it's possible, can you make use of the existing ducting? Has anyone done so or considered it?

Can I ask why you'd want to? Is your engine diesel?

Exactly.

I like the idea of those Webasto Diesel heaters... and I've thought about this actually. What made me decide it was kind of silly was, the B190 already has a furnace that requires carrying a second type of fuel for. Why go through the hassle of replacing it with another furnace that's probably going to have to be jury rigged, that will STILL require carrying a second source of fuel for it? Also, those Webasto's are kind of finicky from my research, much like our generators... they tend to foul up and require a lot of cleaning/maintenance.

Combine this with the fact I've never even used my propane furnace... and if it gets THAT cold I find an outlet and rely on a small 1500btu electric heater...

It would just be a lot of effort and headache to install the diesel furnace without any real appreciable gain that I can think of.

I'm going to be full timing off grid in Canada. On the west coast it can be say 25 degrees for 3 or 4 months. The heater uses a lot of propane and the fan eats power. That combined with the limited propane fill stations, it would be easier to use diesel. Yes, it would be a 3rd fuel source. There are also these propex heaters out of the UK that use gas as a fuel source. It would just be easier not to eat through the propane. Other possibility is the Wave 6, I guess but then I'd have to have a separate propane tank on board. .

Seems like you'd just be eating through diesel instead of propane.

In fact diesel had a lower energy density than propane, so you would actually need more of it than propane to get the same amount of heat.

As someone who has spent many hours underneath a 1991 B190 recently, the only thing I can think of would be replacing one of the gas tanks with a diesel tank... There's not a bunch of extra space under there. Not sure about the later ones.
