My father works in that field. In his opinion heat pumps (with today prices and optimizations) are way overrated. The initial investment and the energy spent (it’s way more than advertised) doesn’t make sense for the average family.

i dont mind the energy spent on a day to day basis because i already have a 5.5kwh solar off grid array. i generate around 30 kwh during a good summer month and a fraction during winters but it gets offset from the grid also.
the grand scheme as i wrote above does not seem cost effective only because of the heat pump. if it were cheaper, i would definitely buy it because radiators/solar water/solar panels are low/no maintenance while heat pump does have it.
