Our rads are being heated by an insert boiler stove and we are looking to change to a different form of heating as having a lot of issues with it. A four bedroom bungalow. We are about to get our attic insulated as there is only a small level of insulation in it since house was built almost 40 years ago. Possibly do cavity insulation in due course also. Any recommendations please for what type of heating we could install. Air to air or electric rads have been mentioned. Does anybody have electric rads and if so is it an expensive way. Any help greatly appreciated please.
