Hi @Nick ? Can i recover this to an acceptable solution without major surgery?

Exactly. Hence my question to my installer. I dont believe they have delivered what i asked for. As it happens, and totally unsolicited the MCS guys have asked if they can audit my install.

The yellow vertical pipes come from the Ashp up through the slab and go left and up to the UVC. They are 28mm. On the manifold picture the 2 pipes come from the UVC area upstairs, they are 22mm. No TMV .

Will do once i get home

How so ? I have had potential installers design for and offer that and i rejected them because its a stupid idea.

I just had a google of TMV. i do not have one of these as far as i can see anywhere.

Apologies for late reply, we moved in over the weekend. What is the TMV, i think i can guess but not aware of it what it looks like or where it might be. Agree of course. Once the house is fully finished and everything optimised i dont expect the radiators to need to do much. But, the fact remains, i asked for a 2 zone installation with control of each independently.

Come to think of it how is the radiator hot water supplied even if there is a temperature control for it? Surely it needs it own diverted hot water. I think i might have a bigger issue than i thought.

Are the TRV’s set to 5, or ‘max’ for the purpose of testing? Yes they are . Can feel a little heat in the radiators today. not suprising as the flow temp will be down in the low 30's . So i think that this demonstrates there is no fundamental issue. Still waiting to hear why the installation company did not deliver what i asked for and therefore believe i paid for. Namely, a second zone, with its own temperature control.

Waiting on a thernal camera but to be honest i have not felt any heat in the radiators. Dont expect much heat and with the current weather dont need it really. But, if there is an issue i need to sort it out soon. At the very least i believe my supplier should have installed a second zone & control for it.

Memory fails me dude. Would you point me in the right direction please

If i understand you correctly its 8.

Thanks johnMo, i will give this a go

There you go, the Booboo might have been me misunderstanding how they worked. I assumed they just did a restricting job on the water flowing through. I did screw down the flow valves on the UFH manifold to the hallway and the downstairs WC last night. The WC is really quite warm. I will check later this afternoon if its made any difference yet. Going for a wired thermostat may not have been the best idea me thinks. Just to say we have not moved in yet but i have been getting ready to do so this weekend.

4 radiators only upstairs, each with a TRV. But the TRV will never become relevant if the warm water is not present at the valve. 35 degree flow nominal , yes WC via the north wall temp sensor Well that forms part of my conversation with my supplier. 2 zones would imply 2 devices of control would it not. I understand that the senso comfort thermostat (vr720/3 i think) can do multiple zones. So i was content when this was specified and fitted. Only has 1 zone configured and i cannot see how to add a zone.

I have a recent 5kw Vaillant heat pump to UFH downstairs and radiators upstairs. One senso comfort wired thermostat in the hallway. Now that the heating is on i find that the ground floor is lovely and cosy. But, because the thermostat gets to temperature the cooler upstairs never asks for heat for the radiators. In all discussions with my heat pump supplier i said i wanted 2 zones but hoped to not need the radiators on. I cannot see a way to control them in my current configuration. Am i missing something ?

I hope they re discover the attitudes they displayed many years ago. Presumably from before they were absorbed by Kingspan. Good luck to them

Have i missed the boat on this one as well. Potton homes appear to have been aquired (spelling) as of today.

Apologies for not responding. Resolved. I was being a twat. Grip the isolator tight enough and undo the nut. The spinning copper into the plastic fitting is irrelevant.

Thanks dude. I did sort of try that but did not want to push too hard in case i killed it. Will have another go later today. I have what i hope is a new one of these on order just in case. Not certain its the same part as the online picture is very poor. Still dont know which place its supposed to connect to on the back of the thermostat.

My Senso comfort wired thermostat has a broken connector. The 2 wire thing that plugs into the rear of the unit. Once i source a new one i need to understand how the wires secure into it. Can anyone throw any light on the subject please. See picture attached.

Now a new conundrum, I need to re do a compression joint that feeds a WC. The upstream side is connected to a piece of copper that is in turn connected to a plastic pipe such that the copper spins freely when i try to undo the nut. I hold the isolator valve with my grips and then undo the nut with a spanner, or rather, i dont becuase the copper pipe turns with it.. Is there a safe way to also grip the copper without risking crushing it? I need 3 hands

Got it

PTFE on Rad valves but 3 or 4 turns only. Need to revisit those. Not used joining compound. I will now though. I have read various conflicting things over the years about not needing to supplement olives for example.
