last time i had a problem with my boiler i was taken to a showroom and had to buy another one, i can still feel the pain i went through when i had 1800 quid relived from my poor dads bank account ( will be mine when he snufs it though

)
not olny was mine too small comparewd the the original he charged me for the bricks for the hole he left, the wiring and fook knows what else
and the fooking think never worked after he left
turned out the gas meter was letting too much gas through making the boilers autoshut off and so never allowed the boiler to light, a saftey measure
sorry i cant help but boilers are a nightmare, just hope this one lasts as long as the other one
