I live in the snowy Great Lakes and I rely on a ground source heat pump and hot water heater full time. No issues at all. Cost similar to a high end gas furnace system when the tax credits were applied. Probably cheaper with air source systems today. I live in the city and don't lose power, but I'm hoping to eventually use a EV as a battery backup when the equipment is available and standards are finalized. A battery in a compact like the Chevy Bolt could power my heating system for several days. It's not like modern gas furnaces don't require power to operate. In a recent Buffalo blizzard power went out and many people with gas heating still froze and had their pipes burst.
