We have been having problems with our boiler for a couple of years now, its only 5 years old, the water is fine but we get no heat, last year we spent £300 on it and in March we spent another £800, apparently its renown for not being a reliable one. Thinks its about time we cut our loses and get a new one. So just trying to get an idea of what is a resonable amount to pay for one. Also, its hrd to find a installer that you trust and you feel that isnt ripping you off, dont suppose anybody knows any good installers/plumbers in Hertfordshire.
