> There also isn’t a low temperature heat pump solution that works for radiators. Can't you use a heat pump to warm water in a boiler, and then pump hot water through a baseboard radiator heating system? Of course, most houses aren't set up for this. Just curious if it's a workable solution, or if I'm overlooking some problem.
