Mind sharing your heat pump and solar setups? How cold does it usually get at night where you are? Any battery to help with the long nights?

$0 is very impressive in the northern hemisphere with no backup heat source, based on my knowledge. Sounds like you're living with the setup I want!

It's a VT subreddit so, as you can assume, I'm in VT. Same temp as anyone else in this state. I don't have a battery, and haven't done much research on them, but I was always under the impression they were like a generator and only used when you lose power. I'd love to be educated if I am wrong about that.

And, I do still have my forced hot air furnace in the house but am actively looking to get that and the oil tank removed.

Same size house, also solar, also heat pump. Our electric is $25, basically GMP minimum charge. But we use 2 cords of wood to make the house a little more more toasty in the morning/evening. Granted, the solar was A LOT. The heat pump is incredibly efficient tho, for example, 20 degrees outside, heat set at 70, after everyone went to bed, our total electricity usage was less than 1 kw per hour.
