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...

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...

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...

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...

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...

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....

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...

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...

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...

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?

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...

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...

thanks kev, you have email!

No, not that I have noticed but will keep a careful eye and ear out. Thanks for the replies, both of you.

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

Ok, Not sure what this is but have noticed that sometimes at night I can hear my pump gently humming in the background. The Ch/HW are both on timed and when I check they are both off and not calling for heat/HW. In fact even if move both the settings for Ch/HW to off the pump remains on. I...

Thanks, yes that would make sense, shame they are not obliged to use the same calculations when they quote output BTU's then. Anyway as I said many thanks.

Is there a reason for a large differnece in output BTU's for radiators of the same style and size? Small differences I get but on a 500mmX1400mm double panel convector radiator the outputs are 6900 btu for a Prorad or 9261 btu for one of the same size and style as supplied by Compass. Any...

Am sure I read yesterday that the minimum spend was £2,000. Yes scheme does require it to be working and I assume they rely on the honesty of the installer for this info, cant imagine they send anyone round. Sent off my application email yesterday -still no reply, not even an acknowledgement.

Mr Hailsham, I dont think anyone was actually arguing over who could apply, just a question thats all. How do they know that the existing boiler is working? Do they need a sworn statement from the installer? I am afraid the information in the form provided tells you very little.
