    I think a need an independent plumber and electrician to come and look over the whole thing make sure its ok and tell how it bloody well works! Sorry just so frustrated with it all.

    My underfloor heating

    Sorry the note I did to accompany those photos seems to have disappeared. There are three white cables coming from the electric box on the back of the hot water tank, they go into trunking. I believe 2 of them emerge at that immersion heater timer, no clue on third one........ The cable that come from unknown switch below immersion clock goes into boiler, there it stops. There is a separate white cable that comes out of the boiler and goes up to the secondary circulating pump (mounted upside down) on the pipe next to the boiler. This pump lights up when boiler in use. Could the third white cable be in this switch? The three black cables that go into the box next to the (what we now know to be) the motorised valve switch....2 of them go up the motorised valves 1 & 2 and these clearly run the manifolds for UFH. The third black cable goes to what looks like a different motorised valve on the copper pipe low down next to tank. In the pic you can just see the bottom of the green circulating pump mounted above. What I did not realise until earlier was that the unknown switch does have some bearing on the immersion timer, I didnt notice yesterday but as well as switching off the boiler and the secondary circulating pump it is connected to the immersion timer. The programme display icon (very small) goes off when switch off. The clock display remain on which is what threw me. I have worked out from the invoices what those various pumps are - I claim no knowledge beyond the description on the invoice.

    @AliG I dont know I didnt do the spec PM did it with installer. I just said I wanted good hot water supply, no dribbling taps. We are single story and plant room a long way from bathrooms so maybe thats why. I dont know I just accepted what they both told me was the necessary spec for my house. ........hiding in corner feeeling stupid again..........

    My underfloor heating

    @Ed Davies @newhome @PeterW @Nickfromwales I have the dymo at the ready LOL, I actually bought it way back about March ready for labelling at handover....of couse handovers never happened, I asked and was ignored. or fobbed off and distracted by other problems going on. On the timer pump theory guess it may be possible in some circs but I have a circulation pump here and I know how they work as have had before. Mine does not operate on time clocks on and off like heating controls it comes on when you turn a tap on whatever time of day and my previous system was the same. I cant imagine having a pump on a tap that would only come on between certain hours what on earth would be the point in it. The timer PeterW and newhome identified is without doubt an immersion timer, as far as I can tell it has never been set up and why would it my hot water is heated by the gas boiler immersion is only a back up (building regs perhaps) and immersion would very likely never be switched on under normal circs hence I am surmising that is why timer not apparently set up. The problem seems to me to be that the immersion has been switched on since install, water came in December so worst case scenario immersion on from December to yesterday continuously. It explains electricity bills so high the company refused my readings and said a meter test would be necessary.........I have had to monitor electricity consumption and report back, its pretty constant. Because of this high electricity useage I wondered if there was an immersion and if it was on so I asked the electrician if I had one and if so where was the switch. He pointed me at what we now know is the switch that controls the motorised valves and me switching it off on his instruction thinking it was immersion knocked the heating out. Electrician is still adamant (without coming and looking) that it is immersion switch not heating valves, have proved him wrong but I am none the wiser about where the immersion switch is and Im not going to start switching random things off I have automated lighting and god knows what I might mess up so immersion is off at trip on CU and no doubt when i check electricity consumption that will have dropped too. Be interesting to see where immersion switch actually is and how electrician deals with having told me quite stroppily I am wrong when he is shown to be wrong when he shows up. God help us if he doesnt know what is wired where!! The temperature in the plant room is noticably lower, the tank does not feel boiling hot all the time either, it feels more normal. I agree with you to install such sytems and not give the user any idea how to use them is very bad, even just marking up switches would have been a help and as you say not coming back is also not good. The electrician and UFH/MVHR installer seemed to have fallen out with each other during the job as did the electrician and the alarm company (who are lovely and did exactly what I wanted on time and at the exact price in their quote.....a rare occurance on this build!) Prima Donna’s why did I end up with them all LOL Hopefully electrician will show in next few days and I will chase MVHR/UFH installer again. I have been on to suppliers and purchased replacements for those missing bits....they are actuators on the flow valves......hopefully installer will fit them when he eventually shows up. I suspect because they all fell out with the erstwhile PM I have suffered from a knock on effect. Not right or fair but I cant think of any other explanarion. I paid them all on the nail never queried anything even though it was always more than their quotes (penalised for messing about by PM usually). I should have been tougher and not paid until they did a proper handover. All water under now I just want to get the place running as it should and never have to ask them to come again.............
  9. @Moira Niedzwiecka mine have been included in my claim. I hope they will be accepted. Will let you know.

    Thanks @Michael P and @Nickfromwales it reminded me we had missing bits. There was a little plastic bag tied to each manifold with bits to be fitted on site (manifolds come ready assembled). Sometime between heating being put on and installer coming back to finish everything the little plastic bags of bits dissappeared....best guess is labourer binned them. Installer was going to ask supplier for repacements but I guess forgot, I have emailed supplier today to ask and hopefully when installer comes back to sort the MVHR he can fit them. After all the testing etc of ufh I feel I have some understanding of the system now....only basic but hugely better than before. I am waiting for the electrician to come, he is adamant that the switch he told me is immersion is the immersion I am just as adamant that if I swith it off the UFH stops working, it clearly powers the motorised valves. He also told me that timer that @PeterW identified for me as immersion timer is a timer for a pump for hot water to the taps and is nothing to do with him plumber should have set it up! I have told him manufacturers website clearly identifies it as immersion timer....beggars belief really why would anyone have a timed pump on their taps, do you only want taps to work between certain hours! In desperation I went to the fuse board flipped the trip for the immersion so it is off (for the first time since installation I now beleive) and then put the switch he reckons was immersion on and off. If it was immersion it would have made no difference as off at board but as we have worked out it runs the motorised valves and sure enough the heating goes off when that switch is off. Have told him all this in an email and asked him to come and identify his switches (nothing is marked) and locate the immersion switch correctly. No response as yet. I feel so grateful to all you lovely people on here for all the help so freely given, without this I would still be going round in circles with misinformation and condescension from the installers ...I can almost hear the ‘stupid woman ignore her’ comments from here. I am armed with the the right info now so they better look out and get it sorted.

    My underfloor heating

    Got some white cables coming out of a box on the back of the tank but they go up inside the wall and no real clue where they go. If I ask electrician what hope of sensible answer after last one.......grrrrrr, might have to get another one in just to check things over. Does the attached look like an immersion control? Its got a clock thats an hour out. Ive never touched it and never been able to work out what it is. Its got 2 cables going into it via some trunking. The tank has 3 cables that come out and go into trunking in a different part of the room...the trunking has junctions so not sure what goes where inside. Guess I had better google the thing in the pic

    Ok guys I think I have a partial answer. That switch that @PeterW and @ProDave commented on - the one the electrician told me was the immersion and to switch it off - if I flip that on the heating works with both manifolds getting warm pdq. @Nickfromwales spot on with wiring problem. So that looks like heating sorted after a thorough work out!! Now the question is where is the immersion heater switch, never ends does it!! Thank you again for all the help.
