    Hi there,
    I have an open vented central heating system powered by a wood stove boiler.
    The boiler is situation downstairs then i have pretty much have the downstairs pipework run off downstairs and the upstairs pipework disappear off upstairs (tee'd behind the boiler).
    The expansion and fill tank is obviously upstairs and i was going to install the pump before the tee to the different floors, is this fine to do?
    I have just read the pump needs to be after the expansion tank on the feed circuit.
    Is it advisable to place it there (worried about circulation on downstairs rad's then!).

    Advise please gents,

    Many thanks,

    What controls have you in place to stop water boiling,what output is the stove,where exactly are you going to BUNG the pump in.If I were you i,d get a Plumber in before you blow the house up.

    Popular misconception that's it's a 'pump'. It's a circulator, lifting heated water & increasing the pressure on the Flow & reducing the pressure on the Return. You central heating system is a Ferrous wheel, if you lift the water to the top(head), it'll drop back down again on free fall.

    Fitting your 'circulator/s' on the Flow you must always have the open part of the system(F&E)on the suction side of your circulator, for the reasons I gave above.

    Yes indeed, watch out for those Ferrous wheels,they rust terribly.

    how are you planning on controlling the pump ?? pipe stat would be best, will stop the water circulating when the water temp drops, is this a new install or a existing ?? more info reqd
