Just got in from a visit to a Heatline boiler, when I arrived the boiler is in bits with combustion chamber front of etc and a bowl underneath catching water, my only reason for this post is I am appalled by what I saw and heard. Earlier on today a Corgi reg guy visited and took apart boiler. He declared the heat exchanger to be broken and that the boiler was rubbish, not worth repairing and he could fit a new one for £1800 I know the guy is registered but it did not stop him leaving a boiler in a dangerous condition, when I arrived you could still turn boiler on and it would still fire up! You could but your hand inside the combustion chamber and cook your marsh mellows on it! In fact no attempt had been made to isolate boiler and at least drain central heating circuit to stop leak, my repair involved replacing 4 orings on the flow and return connections to the heat exchanger and putting it all back together. It’s a cheap boiler but personally I think its ok for the money, maybe a little expensive on parts. Only thing I find wrong with cheap boilers is the installations seem to break every regulation that can be broken. Last week I had a biasi 30kw at the back end of a terraced house and most of the pipe work was 15mm. I explained to the customer that they might has well opted for the 24kw version because they was not even getting that out of there 30kw boiler, now I have run some 28mm in half way across house and the rest in 22mm it works fine, I could have stuck a Worcester bosch on the wall and it would have cost the same to install as a Biasi! Still same amount of pipe work, power flush etc, so why do people think a cheap boiler is cheaper to install?
