i'm considering getting a new (combi) boiler to replace the 20+ year old back boiler/fire combo. Poss. going with a loft mounted unit as it would be directly over the bathroom and near the kitchen (I live in a bungalow). radiators may be good but will need flushing.Would I also need to replace the old fusebox? Anything else I should be thinking about? Any recommendations for a plumber in the Bury,Lancs area?
