Propane furnace sending heat to outside vent
Hi, Running our Suburban propane furnace it seems like the unit is pushing as much (or more) heat out of it's exterior vent as it is to the interior vents. At the vents the flow is a gentle convect...

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.
That is a good point. I suspect also that many RV furnace users would care quite a bit more about improvements to DC power usage than to propane usage; getting an extra night of heating out of a battery bank charge is often of more value than needing to refill the propane a little less frequently. More energy efficient blowers are certainly well within the reach of current technology, though often at the expense of space required.
