I recently had a heat pump installed. My backup is a gas furnace which was all I had prior to the heat pump install. I used to run that furnace off of a generator during a power outage. I'm wondering if there is any potential problem with switching the system to Emergency mode and running the furnace off generator power during a power outage now that a heat pump is in the mix. Seems to me that it would be ok as I assume that is basically what would happen if/when we're on utility power and the heat pump is down, but I'm hoping to get some confirmation or warnings or "hell no" before I set this up. Thanks

Yes dual fuel heat pumps are ok to run. Just Google dual fuel hp several companies make them. Would a want a switch to kill house power when running the generator as to not back feed into the house.

I don't want to run the heat pump during a power outage, just the gas furnace. I would cut the power to the heat pump, power the furnace with the generator and set the system/thermostat to Emergency mode, which as I understand it is heat from the furnace only. My only concern is getting heat during an outage. If there's an outage in warm weather, losing A/C from the heat pump is not a concern.

Gas furnace used as a air handler for heat pump? Or just sitting next to the hp air handler
