This is so bizarre to me that heat pumps are just now being "discovered" by the US mainstream. My old house that was built in 1979 had a geothermal heat pump which was a very new thing back then. Today Switzerland has the most heat-pumps per square meter than any other nation[1]. If you have the money here you get a geothermal heat pump and solar. The fact that there is debate if they even work or they are ugly is ridiculous. The geothermal ones only require a small box in your basement[2] next to your boiler usually. The non geothermal units are cheaper but require quite a bit more space in your basement but you don't even need an outside unit as usually one window is used for intake an another for out.
