I saw this high efficiency combi boiler in a B&Q sale and had to stick in me basket. It's been installed on an existing 1 pipe system well within it's capacity. I can't get hold of the installer which leaves me with no manufacturers warrentee and the following problems:
Turn the heating on and it will light up, nice blue flame, heat all the radiators in the house pretty fast. After 5 or 10 minutes it will shut off and the overheat/flame fail light will come on and stay on until the boiler is reset. Then it will come on for another minute and then do same thing.
Hot water is a strange one - as soon as you demand hot water it will provide ok but when you stop the demand the same overheat/flame fail light will come on. It doesn't matter whether the demand is for 10 seconds or 15 minutes to fill a bath as soon as you turn the hot water off the boiler will need resetting. any advice?
