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

Drake,<br>
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.<br>
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.<br>
The new ECM (electronically commutated motors) pump motors are basically
at DC permanent magnet motor power draws [Taco & Grundfoss] these
days.<br>
<br>
Best of luck with this one.<br>

<br>
<dl>
<dd>Hello Wrenches,<br><br>
<dd>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.<br><br>
<dd>Thank you,<br><br>
