How do you go about finding a gas fitter who is willing to install a condensing boiler? (Not in the true spirit of DIY, I know, but I've read the installation manual and the gas side looks a bit too complicated to DIY.)
After much looking around I think the Keston Celsius25 would be good for what we want, but I've had 4 "central heating engineers" come round now, from a variety of big and small organisations, when I tell them what I want to do they all suck air through their teeth and try to persuade me to get a cheap combi. They then come out with a stream of bizarre reasoning - Kestons don't like microbore, condensing boilers are a waste of money, Kestons don't work with normal control systems because of voltage leaks, it'll be broken in 10 years anyway so you may as well get a cheap one....
I'm in Hull, there must be someone in the east riding of Yorkshire who knows about these things and won't run scared?
