I was just wondering if anyone knows what the going rate would be for a new boiler to be installed? I know nothing about them (other than I think they're all condensing combi now?). The figures 80 and 100 have been mentioned (power?). Our current combi boiler (which is at least 10 years old we reckon) for our 3 bed house with about 11 radiators won't give us hot water when the heating is on, and the heating itself only warms the rads up for about half an hour. We found a plumber who can't work out what's wrong and is about to come and replace a second part (as the first made no difference). Don't get me wrong - we trust him but he's saying a new boiler may be the next step. He quoted £1200 at first, then came back saying we could get a decent one for £900ish fitted. Does anyone have a better idea?
