I've just had the heating engineer round to look at my dodgy Alpha 240P boiler - I think it's on its last legs...he suggested replacing it for a Worcester-Bosch Greenstar 37CDi. Old boiler was obviously really inadequate in terms of of output but he did notice one sticking problem to installing a new one - the gas supply pipe.
Now from the meter the gas supply runs alongside the house then disappears into a wall all good up to here because it's 22mm copper pipe (it's not sleeved going through the wall but I can live with that). Problem is the gas supply pipe enters my kitchen at 15mm and there's some monkey work gone on just below the boiler to transfer to the inlet size of the boiler (22mm). Total length overall is approx 10m, anywhere between 5m and 7m is 22mm with the remainder being 15mm. There are about nine 90 degree elbows in the supply pipe to the boiler and there is a 15mm branch to my 4 burner gas hob.
I don't think I can get away with the supply pipe as it currently stands, how much do you think it would cost to have someone lift the carpet in the bedroom, find the supply pipe in the floor void and fit 22mm for the remainder of the run to the boiler? Obviously a lot of factors but rough guide for that sort of work? If anyone knows of any tables where I could work out what diameter pipe is needed (if greater than 22mm) that would be great.
I'm in Dorchester so if anyone can recommend any quality fitters I'd appreciate it. I really wish they wouldn't let people who are willing to do this sort of cowboy work anywhere near houses!
