Is it a pump speed setting or pump problem?

    Hi

    I've read as much as I can on this but I'm sure I'm missing something so any advice would be great.

    Its a two story house and there are three pumps in the downstairs cupboard

    There is a thermostat upstairs and downstairs for independent control.

    However, if you want to have heating upstairs, you have to turn the thermostat down to its lowest downstairs

    To heat downstairs you have to do the opposite. I have bled all the radiators and they get nice and hot.

    There is no pressure guage anywhere.

    Each of the three pumps has three speed settings and all are set to low.

    I'm not sure which pump is for upstairs and which is for downstairs.

    Should I adjust the speed settings? I know going too high is wrong too so I really would appreciate any help to get them all working together.

    Thanks for your help

    It sounds to me that you have flow distribution / balance issues.
    There may be a simple fix to it, but to fully rectify it may be like trying to give you a haircut over the phone.
    First off ensure that the balance valve on the central heating pipes to the hot water cylinder is only open approx 1 and 1/2 turns from closed.
    Turn the upstairs and downstairs pump speeds up to 2 or mid setting.
    See how that works.

    Apologies for the delay responding, I've not been home to try this until tonight.

    I think one of the pumps is definitely dead, or something wrong with it and I think that's the upstairs one.

    Regardless of the speed setting, it's silent and stone cold. I'm guessing that's been the problem. I might have a look at it and see if it's just seized if that's worth doing.

    Even so, at least I've a better idea what's wrong.

    Be so glad to get this sorted.

    after trying a few things suggested, I am fairly sure that the pump is not getting any power and have been told that it might be a capacitor issue?:confused:

    Is it easy to find someone that could test this and repair or replace it?

    The pump is not that old. Maybe its worth trying before I ask a plumber to replace it?

    Any suggestions?
