As someone who lives in a climate that pretty reliably sees -40C and a week of the mid -30's ever year I think that the only option is a ground source heat pump - I can't see an air heat pump putting out 80,000 BTUs when it is at its least efficient.
I wonder how that works for a city - is the idea that everyone drills their own 15 foot hole? Our frost can reach down to ~8 feet.
- sbradford26 5y agoThe solutions I have seen for cities would be community/public ground loops. Piping would run similar to potable water but would return to a centralized location where they would have large wells. This would be impractical for suburban/rural environments but denser cities it would most likely work.
- Ekaros 5y agoPretty standard in Nordic countries. The source of heat is real question, but there are some options like burning garbage, or waste heat from factories, data centres and so on.
- sbradford26 5y agoThe source could also simply be the ground. With a heat pump the water doesn't have to be hot to provide heat to a building. The difference with the system Nordic countries have is that they provide hot water to residences which is directly used for heating.
