The down and dirty of coach heat

[TomC]

Lets go over this-with hydronic, you'll probably have 5 heat exchangers-one in the bathroom and 4 in the bus all with electric fans. Then the main unit with pumps, coolant hoses going to the engine, heat exchangers, Diesel nozzle and combustion chamber to take care of-all for the for mentioned about $10-12,000 for new system.

With propane heating, you have one or two forced air furnaces with one motor each. I use 2-10gal elec water heaters that I haven't done a thing to (except drain once a year) for hot water, and have electric block heater. Granted you have a propane tank that you have to refill periodically. I use propane for cooking also. My furnace, stove, and propane tank cost about $1200. Like all things bus-it is what you want to deal with. I like the k.i.s.s. method. Good Luck, TomC

me too. that's where all electric shines.

And...how often do we get propane furnace issue questions compared to aqua hot and webasto issue questions.

[eagle19952]

a webasto burner is almost as noisy as a generator...

This is appropriate. Our last night up north this winter:

If you're expecting cold weather, insulation is every bit as important as heat.  Note the depth of snow on our roof in this shot from the winter of 08/09.  This was outside Ottawa - probably -20C at the time.  Its already been mentioned but the other big consideration is the location of your water manifolds and connections.  Our mechanical bay stayed warm with just the heat shed by the Proheat but the manifolds were in a really stupid location and they took a dedicated 1500W cube heater just to keep them mostly thawed once we got around -20C.  On a 30 amp service that meant 1/2 of our incoming power was devoted to keeping the water usable.

Bob, those are awesome winter bus shots!! Our coach does get snow buildup like that on the roof so I know the insulation is good. But yeah those are cold temps you're mentioning!!

If you are talking about temperatures below freezing F, then the snow would serve as insulation, right?

I suppose in theory it does something but if there's heat going out through your roof it turns the snow to water pretty quick.  If you look closely at the 2nd photo you can see where the heat from the fridge roof vent has melted the snow around it.

While we were in Michigan I stopped by our new bus who is patiently waiting in the cold for us to come back this summer and start converting her she's a beauty. And she WILL have proper heat.
