Buderus GB142/45 boiler hissing sounds

Hi Everyone,

Some strange sounds are coming out from my three years old Buderus GB142/45 boiler from last few hours. I have tried to find out the exact reason behind it after reading the user guide but no success. Is it something serious?

Thanks in Advance

James

Hi James,

Actually, hard salts have deeply precipitated on the heat exchanger’s surface thus; causing a very thin layer of the scale or else these has been an inflow of other problem causing deposit into your boiler. You can add a noise-dropping chemical. In extreme cases, you can remove sludge and scale from the whole system with the help of a suitable cleaner. It will ensure that your boiler is free of debris.
