The toaster element slots in after the heat pump portion. You don't need the heat coil if you're in a temperate climate as the unit will work just fine without it, but if you can install one it helps defrost cycles to go quicker and gives an emergency backup. | |

I'm sure you could acquire a "wish furnace" which had no "meat" and merely provided the air handler, but given economies of scale, it would probably be more costly than a commodity gas furnace. They do make electric forced-air furnaces with enormous resistive "toaster" elements where the gas burners would be - that is the traditional "emergency heat" for old generation heat pumps. They require a ton of electric service though. | |

| Dec 16, 2022 at 15:13 | comment | added | dfitzgerald | @Harper-ReinstateMonica After having talked to some HVAC companies, they are all pushing keeping the gas furnace as backup heat. If I'm understanding you correctly, that's a reasonable way to go and, if I so desire, I can essentially never use the gas heat? | |

The pipes might get enough heat through the wall to not freeze, but when the bathroom is closed off different deal all of a sudden. | |
| Dec 16, 2022 at 6:38 | comment | added | KMJ | Gotta say, this is the first house I've lived in with a duct in the bathroom. I've never thought they were too cold since the adjacent room was always heated and we leave the bathroom door open. Is it a major problem in the snow belt? | |
