Hi. Can anyone recommend a specific condensing boiler (not combi) please? I've just bought a 3 bedroomed, mid terrace, insulated brick cavity walled house that isn't huge (maybe 52m2 in total) and don't know which boiler to buy or what the heat output should be. I've heard Valliant are the best but someone else mentioned Worcester and I haven't got a clue. Please help... :?
