More Heat Pump Questions

[SCVJeff]

I don't think anyone is considering routing the heat exhaust back in the coach. On the other hand, attrition of the terminally stupid isn't a bad thing sometimes. Kind of like the people that set off 20 bug bombs without killing the pilot light and wonder why the house just blew up.

Anyway, not being a thermal design engineer I can only comment that I find it interesting that one cannot build a more efficient heat exchanger and then turn down the burner. There is an incredible amount off heat lost out that vent.

I wonder if anyone has seen the efficiency of these furnaces?
