I asked my Norwegian and Swedish friends about heat pumps, and the general answer was that they did their job, but if you get one with a squeaky fan in the neighbourhood, you'll be wearing earplugs until it is sorted. Most civil buildings run on very large heat pumps installations that can take up "several parking spaces" or are installed on rooftops.

Water heating for sinks all tend to be on-demand electric boilers right next to the sink. All washing machines are cold fill and tend to be used at night, and all showers are electric.
