is it easy to add another radiator? Our boiler is in the garage and we would like a radiator in there with the intention of converting it properly one day. I’m thinking in the long run it might be cheaper to pay to have a radiator installed than run an expensive electric heater. Am I right? I’m presuming that because it’s in the same room as the boiler it should be easier than wanting to install one at the other end of the house.
