Mine also uses electricity but a very small amount. When the power goes out I use a car battery, with a mini generator or my car to recharge. Also use it for my well water pump. (Afaik I'd need substantially more power for an electric heat pump for 2 weeks)
- cmrdporcupine 4y agoInteresting. My well water pump is 220v and draws quite a few amps. At least on start. I don't think I could run it off my "backup generation" (12amp 120v outlet coming out of my Outlander PHEV). It's also hard wired right to the panel.
- amluto 4y agoSome pumps can be connected to some sort of soft start circuit. Others, especially three phase pumps, can run off a VFD that will start it quite gently. (And those VFDs run off single phase power just fine — they create a third phase internally.) And some pumps (e.g. Grundfos SQE) have their own drives down the hole.
- cmrdporcupine 4y agoI actually have no idea how old my well pump is, but it predates both myself and the previous owners. So probably 1970s or 80s.
