More effective at low temperatures maybe. More efficient, no.
There are ways to heat 100% electrically without the cheap heat system while preventing plumbing freeze up while NOT disabling the propane furnace. For me, that is a deal breaker on cheap heat. They could fix it, if they wished, but they don't.
I don't understand what you're saying. The CheapHeat system in our 5th wheel doesn't disable the propane furnace. Ours has a rocker switch in the control cabinet with the thermostat that allows the user to select either "Electric" or "Propane" mode for the furnace. I've operated the furnace in both modes.
