Underfloor temperature limiting valve

[CrazyFool]

Hi Guys

Does anybody have any experience in working with one of these:

RTL valve Underfloor heating return temperature limiter thermostat UBG insert 5902693830900 | eBay

or

RTL-MB3 Return Limiter for underfloor heating Valve Temperature Cassette Box | eBay

its basically a TRV that measures the temperature of the actual water rather than the air.

Its designed for small spaces - 4 square meters, so can run off the existing central heating loop.

Polypipe and Danfoss make one too, but if it's just a TRV I'm not sure if I should pay extra for the above brands.

I would be grateful for any feedback.

Cheers

Limiting under floor heating temperatures is a vital safety issue. Using cheap stuff is not best practice. Honeywell, Drayton or Danfoss are good
reliable manufacturers..everybody on UKPF will have their favourites

Personally I have never seen these in England but for a small system either should be ok .
I have a temp/pressure limiting valve on my ufh , and all it does is lies there in case anything is going to go ***’* up and closes off the ufh. However it doesn't regulate a mixing temperature .
