Need help identifying valve please

[Dave M.]

Hi

i have this valve on my underfloor heating manifold. It mixes the hot water from the boiler with the recirculated water from the heating loops. It has a remote sensor in the path of the mixed water on the input of the heating loops. The valve head looks like a radiator valve, except it is marked from 30 to 70 degrees. I need to replace it, as it only works up to just under 35 degrees. Any hotter than that and it just feeds hot water straight from the boiler through the heating loops. I'm happy enough replacing it myself, just can't find a replacement part. I've been searching for thermostatic valves but no joy. Help appreciated.

is there any markings on the manifold and looks somewhat like a remote trv/ control valve

Have a look at uponor. They have manifolds with something similar.

Or Wunda floor, looks like there kit.

It is a wundafloor manifold. Didn't think of looking on their site, assumed it wasn't part of the kit. Looks like I was wrong. Do they sell spares? I don't see an obvious online shop on their website...

best to phone them up and ask but i would think so

Thanks all. Will do

It probably works fine. The copper thermostat should be pushed all the way on and secured with a split pin.
It won't be sensing the hot water while in open Air

It's worked fine for the last 5 years, but when I turned the heating on this winter, it didn't. guessing it needs replacing...

Well it just gets better. Rang wundafloor today and even though I couldn't provide any paperwork, they still found my order on their system 5 years after it was installed and insisted on sending me a free replacement next day delivery. Couldn't be happier.
