Beat the winter chills: A guide to electric heating

Like heat pump systems whether they be reverse-cycle air conditioners or hydronic heat pumps resistive heaters can be used to make best use of any excess solar PV generation on a sunny winter's day If you live in an area that has a good number of such days then using a heater that approximately matches the exported excess can mean you are heating for significantly lower cost Of course
