PS some heat pumps are reversible so that you can use them for cooling like AC units.
Yep. We have two air pumps units in the house, one upstairs and one downstairs and they're awesome in summer and winter. On blisteringly hot days I'm so happy with have them.
It's a little bit different over here as, in this kind of house, its recommended you have two different heating systems in case one breaks. As our other system did last winter and so I can see why that makes sense. We now have geothermal for the main house heating (hot water, underfloor heating and a few radiators where that doesn't reach) with the pumps as backup. However, it could easily be set the other way around.
Big thumbs up for pumps from me. Even bigger thumbs up for geothermal if it brings the savings promised.
