Does Wet UFH need a floor temp sensor
Discussion
Investigating UFH heating kits for our extension. I was planning on using a Nest (as we already have one) to control it.
However I've realised I'm not sure you can configure the Nest with a floor temperature sensor.
Is one of these needed? Is there a way of plugging one into a nest? Or should I consider a different controller type.

Floor temp is very different to room temp and the probe will keep a tighter control on it all.
Thats why most UFH stats come with one.
Although they are available as an option on UFH, you do not need a floor sensor.Thats why most UFH stats come with one.
I’ve now had four houses with Wet UFH and none have ever had a floor sensor.
Set the manifold to the required heat depending on floor makeup, mines on 45 for concrete, and let the thermostats do their thing.

Just because you control it via the manifold, that doesn't mean any future owners of the property will.

As I said, I’ve had four systems without a floor sensor and know of many others without. Maybe your experience differs to mine.

One UFH zone, Plus radiators. Currently on a combi. Plan to install S-Plan with two motorised valves and link the Nests that way (as per the Nest install guidelines.
Need to check Heatmiser and the like though to see if they're a better idea.

I've just done 3 zones of UFH(diy).
I got it from here in the end https://www.vpsunderfloorheating.co.uk/
Its a hetta manifold and pipe, really good quality compared to most. Heatmiser controls. I had loads of extra heating bits off them(zone valves etc) as they were so good to deal with and very well priced.

This thread has got me thinking....
I've just (this weekend) had the rest of the Amtico laid in our house, with this final section being over the wet UFH.
I have a Nest thermostat for the dining room/kitchen, which controls the UFH and a separate Nest for the radiators in the rest of the house.
The Nests work fine, but the limit on temperature for the Amtico - 27 deg - means that, because I don't have a probe, the air temperature at the nest is going to be somewhat different from the floor temperature.
Other than common sense (I have a wife and a daughter to challenge that concept), anything else that would help? Infrared heat sensor?

That temp does seem to be what is quoted, seems really odd though, I take it you cannot walk on it in bare feet and have to shield it from direct sunlight even if you not have UFH?I've just (this weekend) had the rest of the Amtico laid in our house, with this final section being over the wet UFH.
