UFH sensors in the floor or on the wall?

I'd put the temperature sensor on the room not the floor because I care about the temperature of the room but not about the temperature of the floor (within limits)

wall. Who cares what the floor is at? Its the room temp you need to monitor.

next Q ?

No, you mean the syetem isolation switch :-)

SWMBO who is used to a 'throw in coal, and use back door to regulate temp' needs retraining here, I feel...:-)

"Does anyone have an idea on what is the best for temperature control in the house?"

A room temperature sensor (not a thermostat) controlling the heating flow temperature. The heating flow temperature is measured by an immersion sensor at the outlet of a 3-port mixing valve. If you have a non-condensing boiler, the heating flow temperature should also be restricted, to ensure that the boiler return temperature (another immersion sensor) doesn't fall below 60degC.
