CheapHeat furnace conversion
I was wondering if anyone has converted their factory installed LP furnace to the CheapHeat system. Seems like a very practical system when connected to shore power. No worrying about running out of g...

Most of the time I run on low speed, much quieter. When we are in temperatures below freezing I switch to high to help move more heated air through the holding tank area. Dont know if its necessary but I would rather be on the safe side.
Going to get technical on you Harold.
1. Do you know if they reduce the voltage to run it slower or do they use some sort of PWM motor speed control to slow it down.
It is done by switching to lower voltage in the control panel.
2. Give me an idea of your average run time on a colder day. My mind is thinking it would be more desirable to have it run longer or continually as it would become a low back ground noise. I would think the furnace motor would be up to the task but if they simply use lower voltage (say 6 volts) to run the motor how does the motor hold up under this kind of service. I'm thinking as long as its no where near stalling it wouldn't matter.
Today the high was 56F, with the thermostat set at 70F. The furnace would turn on about once every hour and run about 10 minutes, running on low. This is our fourth winter with the system and no motor issues.
Comments??
Thanks again.
