Hi
My house is only 3 years old and due to being badly installed the housebuilder replaced my old boiler, last May, with a new Powermax 155x boiler.
Things were ok for a few months but now (nearly always in the mornings) there is a trememndous bang (like a gun shot) usually happens twice in a row, shortly after it has fired up in the mornings. Sounds like someone hitting the side of the boiler with a hammer. The engineer from Powermax came out and of course because it doesn't happen after the boiler has been on for a while, went away saying "no fault found"
Someone has suggested "sludge" in the system since when the engineer replaced the old boiler he found that no inhibitor had been put in the header tank and having drained the system had a terrific problem because all the rubbish from the header dropped into the system.
He did jet it through and put 2 loads of "cleanser" through the system!!??
Very grateful for anything from the experts out there.
