    Valiant combo pressure keeps rising

    My sister had one of these go on a Vaillant Ecotec 831 last month, 2 months out of the 5 year warranty. The original fitters came and charged her £285 to replace. They had sent someone the week before to do the annual service and it cost £90, it was a young lad who was there no more than 20...

    Lounge Radiator that only works when bedroom radiator switched on.

    great tips dilalio, thanks a lot. also thanks to jeff for reverse circualtion theory, something that i have been contemplating myself. Is this common? And would it be caused by one pipe being heavily blocked, thus making the water run round the other way as in the path of least resistance? i...

    Lounge Radiator that only works when bedroom radiator switched on.

    Thanks to Dilalio, Nige and Mr Hailsham for taking the time to reply and try to help. Looks like its the bucket test, followed by maybe some Sentinel 800, and if all else fails a floor cutter! Quick question as regards the Bucket test, just to clarify, I remove the Lounge radiator (with both...

    Lounge Radiator that only works when bedroom radiator switched on.

    Henry, No it doesn't. I can see and feel the pipe work under my bedroom floor, the feed is 22ml and red hot, there is a return pipe (I assume) that is 15ml which remains stone cold until the bedroom is switched on, then it gets hot then the lounge radiator warms up. I am wandering now that if...

    One Bad Rad

    Alan, interesting reply, similar to the issues I am suffering (plus a few more). tell me would the same bucket test and pressure type fix work with a sealed combi system, if so what differs from the above method? many thanks...

    Lounge Radiator that only works when bedroom radiator switched on.

    Thanks again, In that case it cannot be plumbed in series then, switched off both sides of lounge radiator, and my bedroom stayed piping hot, didnt drop the temperature at all in nearly an hour. Shame! Like i say, think i need a scientist....

    Lounge Radiator that only works when bedroom radiator switched on.

    Thank you ScottishgasMan, kind of you reply. i did consider it was maybe plumbed incorrectly, but my thinking on this was that as the other two rads (bathroom and small bedroom), run as they should then this might not be the case. and in answer to your question , if i turn the lounge rad off...

    Lounge Radiator that only works when bedroom radiator switched on.

    Hi all, Here I have an issue with my central heating and the way water flows through and returns using 10mm small bore pipe work. Now I realise that what I have is pretty old, and probably pretty sludged up and needs replacing, but despite all this before I replace I need to know whats going on...

    drayton ZA5 2 port issue. Function of microswitches

    I have laid on my stomach for the past hour, tried taking photos, tried using a mirror but still cannot see any A or B on the brass valve body. However I do notice that the valve for the C/H is set horizontally with the wiring plug nearest the pump.On the H/W its the other way round, the wiring...

    drayton ZA5 2 port issue. Function of microswitches

    This I need to check, I would have assumed the valve was the right way round as has worked fine for years. Does the lever on the side with labels A and B refer to ports then?

    drayton ZA5 2 port issue. Function of microswitches

    one other thing has occurred to me, the water hammer that appears to be stopping the valve from fully closing, is this normal? What I am saying is even if the microswitch was working properly and stopping the pump and boiler from running, the H/W could be calling for heat and as such the pump...

    drayton ZA5 2 port issue. Function of microswitches

    Ok, My issue is that the Drayton ZA5 port on the central heating circuit does not shut off , either when the correct temp has been reached on the wall thermostat or if I manually switch the heating off from the programmer. What actually happens is that the valve makes a very loud clanking...

    Pump still running -even when CH/Hot Water off!

    I am afraid that its an old Gloworm Micron 30ff. No a great boiler by all acounts but it works (sort of).
