We have an air source heat pump as auxiliary bedroom heating - and cooling in summer, otherwise known as an air conditioning unit.
I suspect that for the house heating a larger version may be an option, but it does mean upgrading all the radiators as the circulating water is not as hot as a gas boiler.



They are better suited to wet underfloor heating systems rather than radiators, where you want a warm floor over a large area rather than a red hot radiator with a comparatively small surface area.
