Just after a bit of advice. We have currently got a boiler in the kitchen and a water tank in the airing cupboard. Hoping to put a combi in the airing cupboard instead but not sure which to get.(Or is there something better?) When we had central heating in the old house we went for the cheapest as we were not planning on staying there, but the new house will be home for a few years so could do with something decent. (the last one took hours to run a bath!!!) Need to run 5 rads from it. Anyone seen any bargains recently?
