Thermostat that can time use of two different furnaces?
I’m thinking about installing a heat pump in my home’s forced air system, but electricity from my utility is prohibitively expensive between 3pm and midnight. Assuming that I leave in place the existing natural gas furnace, are there thermostats that can be programmed to, for instance, use only the gas furnace between 3pm and midnight, and to use the heat pump during other hours?
