> they have an outdoor heated pool, though, so crazy as it sounds they are presumably using electricity to heat it.
That’s an almost ideal case for an air-to-water heat pump though, the heat capacity and efficiency of which go up as the output water temperature goes down. Pool heating (and snow melting) are ideal use cases that can support a very low output water temperature and still get the job done (as compared to baseboard or cast-iron radiator space heating).
