With cheap heat you still have to listen to the noisy furnace fan, right?
Kinda. It runs at half speed (if selected). Did a little test the other day and ran one of our furnace motors at 6 volts instead of 12. I was surprised how quiet it was. I know the new dual stage Atwood furnaces also have this option. They kick down to half blower and half burner when within a few degrees of set point. Both our furnaces are hanging in there after 10 years of full time use but when they pack it in I would consider going to the new dual stage for this reason. In my case I used 6 volts to spin the motor just to hear what it would sound like. I wonder if they just drop the voltage or if they use something like a PWM type control. Anybody know?
