Thank you SpecialK, actually I have got individual temperature control, and hence actuators on each circuit. The idea here is to get the supply temperature right.

OK, so I have tried to find the blending valve online. The model that matches visually is the Ecomix nickel plated mixer set UFH-EM15NP. This has a 30 to 65 degrees centigrade operating range apparently, which would suggest that it should work.

Ah, interesting roguetrader, it could be the wrong type of valve then. That could explain why it's not working in this particular installation.

OK, so the problem valve, by taking the knob off and adjusting it as far as I can I could get the temperature down to 46, so about 12 degrees above where it needs to be. I guess it could be that the pipe that feeds the return (cold) water is blocked. Can anyone think of anything else that...

Yes, it is annoying and seemingly unnecessary having two different types of valve. Though I have to say that two valves that work would be the ideal, rather than two that don't. I note that the heating was never set up. Nothing was balanced. Indeed, the installers did not seem to know that it...

Will have to wait a while. Obviously, after heating the room a little with the valve as it was, both the supply and return are pretty hot. It'll take a while for the water to cool and for the blender valve to not just be mixing hot water with more hot water :)! I assume that if this does not...

So, checked and yes, one of the connections is marked in red and that's the one where the hot feeds in. So, it does seem to be plumbed the right way around. I am now checking the extra range of adjustment on the valve to see if that helps.

Yes, the term 'blending valve' makes sense to me. That's exactly what it's doing.

Will do. At least I can check that the two circuits are the same.

Ah, so removing the knob (Philips screw holding the plastic knob and aluminium printed disc), it seems like you can wind the valve further. It's as if the valve has an operational range but you can alter that range by removing the knob, turning the valve spigot and replacing the knob in a...

Hey Oilhead, we crossed over. Thank you for your reply. I'll try and look for some lever or button that might lock the valve open.

In case it helps, the calibrated control that is working is branded 'Reliance' (are they called tempering valves?). The uncalibrated control that doesn't work is labelled Inta, which I think stands for Intatec. I would not want to put any blame on the device till I understand the issues though.

Hi. I am new to underfloor heating. I am in a new build. I have two pumps feeding two manifolds connected in parallel and feeding two different ground floor levels. There is a hot/cold mix dial for each so supply hot water is diluted to a lower temperature as I understand. While balancing, I set...

I have a pair of doors which open back against deep reveals. Fully open, ordinary handles would prevent the doors laying flush against the reveals. In fact they would make the doors stand quite proud of the reveals. So, I need flush or low-profile (12, maybe 18mm) door handles on that side of...

Ah, thanks both. Just to be clear then, the builders are doing all this, they just told me for my information as it were. So I'm sure that all the right language was used between the inspector and them. I'm just being curious with question 2.
