Soon I will have access to a small 2 bed flat with an old back boiler and gas fire which I am frightened of. I had discussed with an engineer who was power flushing my own central heating system and he said I would probably need to replace all the radiators as they are single fins as well as the boiler (I don't want another back boiler, I want a combi boiler) is this correct. I am in Glasgow. Thanks
