Dana,
Your comments, and other comments on this list have made me see the
light. We are going to go with a boiler.
What is the best source of equipment for this application these days?
Many years ago, I helped install a system in Colorado using El Sid
pumps, with guidance from you, if you recall this ancient history.
Cheers,
Drake

Drake,
All the conventional units I have amp clamped over the years are
pushing 900-900+ watts per hour. I do not recommend them ever & to
date I have never found a lower wattage blower. I would assume that
a permanent magnet motor would fit this suggestion, but I have not found one.
For off grid I recommend: Radiant floor heat first and hot water
base board second long before hot air. Air is a better insulator
than a heat transfer agent.
The new ECM (electronically commutated motors) pump motors are
basically at DC permanent magnet motor power draws [Taco &
Grundfoss] these days.
Best of luck with this one.

Subject: [RE-wrenches] Forced air Furnace
Hello Wrenches,
What is the best choice for a propane, forced air furnace for an off
grid house? We would prefer one that doesn't have a phantom load,
although the transformer for the thermostat may not be avoidable.
Low blower current would be preferable. The furnace AC will be
powered by a Magnum 4448 PAE.
Thank you,
Drake
