    Hi All,

    A bit of advice please, I have a dual heating system oil boiler and back boiler behind fireplace.Recently I installed a chimney balloon fed up of all the mess and to stop using fireplace, I now find the back boiler is heating up like a radiator (probably always did but heat disappeared up the flue).What do I need to do to stop the back boiler heating up.

    It will need to be checked over as it is either missing or has a faulty non-return valve. The location of the non-return valve is also important.
