    Hi

    Problem solved!

    I turned down the pump speed and the reduction in noise has been phenomenal. Absolutely incredible. And I get hot water as normal.

    I'd spent a lot of time reading user and installation manuals, scouring the Net, phoning plumbers etc but never once hit on the pump speed solution. So the gems of information in this forum are very much appreciated.

    Thank you.

    Les

    sounds like your boiler might not have an automatic diverter valve and if it does it may need adjusting make sure the radiators on the room with the thermostat are on ordinary radiator valves and not closed. I would suggest getting a qualified heating engineer to check over your system
