Hi I have a "barlo balmoral" wall mounted central heating boiler.=Prob:After it has been on for some while it gets very noisy.Its like gravel being dropped onto glass. The only way to stop it is to turn it off for a few hours. I know I will have to get a plumber, but I would like an opinion first.The system is at least 5 yrs old.-Any ideas.Thanks. Regards Dave. |
