    combi boiler reduced flow after mag one internal replaced

    its a grant, not sure what model. Today I emptied the balls out of the combimate and cleaned behind the red plastic inner which was thick with whatever the balls are made of. Thought that might have solved it but the flow is only slightly better at the showers but still not enough to run hot...

    combi boiler reduced flow after mag one internal replaced

    Thanks very much for your knowledge, the mag one must be a red herring. Any ideas what might cause my problem please?

    combi boiler reduced flow after mag one internal replaced

    I have a grant combi boiler with a combimate and Mag One fitted it the system. Recently the Mag One started leaking. Heating engineer replaced whatever is inside and cured the leak. Since then, the shower is feeble and there isn't enough hot water to overcome the cold water pressure in the basin...

    boiler cuts out via cylinder stat

    Thanks DP. I'll give a trusted sparky a ring now I have your wiring diagram. Probably have to wait til after Crimble now but at least I can fire the boiler up by running off hot water. Just have to keep cleaning things!

    boiler cuts out via cylinder stat

    Thanks for the answers. I had already had the valve electrical bit replaced by another Grant approved engineer because the rads came on when HW selected. We just lived with it for a year. Then the boiler started cutting out and the next Grant bloke said it was air. Consequently Ive spent 6...

    boiler cuts out via cylinder stat

    I have a vented system with a bog standard Grant external boiler. Basic Drayton timer and room stat. Radiators all come on even if only HW is selected. The boiler cuts out when hot water reaches temp. I've proved this by turning the stat up and boiler fires up. The Grant approved engineer...

    combimate or magnetic conditioner, which is best

    I have a Combimate fitted about 450mm above a Grant combo boiler in a very warm room (29ish degrees C). A different heating engineer to the one who fitted it 6 years ago, says I should replace it with a magnetic water conditioner as the Combimate can do more harm than good to the boiler. what...
