Look to your current heater's BTU capacity, and look to the BTU capacity of the heat pump you're looking at, particularly at different outside air temperatures. We have a decently insulated 1,800-ish square foot house (but not without some serious air leaking from the basement that we hope to one day address), and if we wanted to rely on our one heat pump alone it would keep the house comfortable until the absolute coldest nights, and even then I don't think pipes would freeze!. If we were trying to heat with only heat pumps we would probably need a second unit.
Most folks here see them as supplemental heat, plus air conditioning, as you describe, which is the mindset that efficiency Maine is trying to move beyond in the linked article! I think it would work for you, though it can depend a bit on house layout (works best if the unit can blow air in a way that circulates more than just one room) |

I take your point that you need the right size unit for the job required.
my point was if there is nowhere to locate said unit due to lack of actual space or the noise generated, or if it isn't possible to improve insulation to required standard, then even if it is proven to work, it isn't a viable option. I can see it could be great if you have a modern well insulated house with lots of space around it, but the vast majority of housing in the uk is not like that. Plus I suspect electricity costs a lot more here than there, which is another factor.
There is backlash against ASHPs in the uk because the gov has issued grants, for something that is largely attractive to those that are better off - and can afford that home with lots of outside space and potentially higher electricity bills, whereas perhaps that money ought to be spent on communal systems for terraced houses and blocks of flats. |
Communal makes a load more sense in general in the UK.
My house is hardly small, but even here I struggle to see where a heat pump would fit, and I can't think of any properties I have ever lived in where it would have easily fitted. |
