Whenever I see someone post something like this, I wonder. WHY do you not do that. You will be a millionaire in no time. There is a BIG difference between the design of a RV furnace and a HOME furnace. There are space considerations you have in an RV that you do not usually have in a Home system. Doug

I under stand what you are saying, but the majority of owner's only look at the cost of things, not at how much it cost to operate.
Williamson furnaces were one of the best and efficient home furnace. Many home owners recognized that and used them even though they cost more. But Williamson went belly up.
The reason that we have the high efficient home furnace today is because our government demanded it.

I'm not an engineer, and I'm not sure about all the safety requirements, and I'm not sure I could find all the parts I would need.
I have many other things to do, but if I had a good working RV furnace to play with perhaps I would give it a try.
But would it sell well enough to produce? I doubt it sell well, as it would cost more.

I agree with Dusty. The other thing to think about is how often or long the typical RV furnace is run. We travel a lot, 3 months/year is common. I doubt I use more than $50 of propane each year for heat. Increasing the efficiency of an RV furnace from 60 percent to 90 percent wouldn't make much of a dent in my propane cost, so the extra cost of the furnace would need to be minimal.


In reality I would easily pay more for a quieter furnace, way more likely to do that than pay more for a higher efficiency furnace.
