I would like to use Google Nest with my underfloor heating system which is under a wooden floor. Other thermostats allow the user of a floor sensor which monitors the surface temperature of the floor - a probe sitting between pipes at floor level. If the sensor records a floor surface temperature of 27 C it will shut off the system to avoid damage to the floor, even if the room is not yet up.to desired temperature.

My question is - can I achieve this with Google's Nest and Heat Link products here in the UK?

Google's support wouldn't help me, instead referring me to Nest Pros, who understandably didn't want to spend time giving me free advice. I've been searching for days online and cannot find anything that gives me a definitive answer.

Many, many thanks if you can help me solve this! The Nest Pro I did manage to engage in a conversation said it could be done, but wouldn't tell me how. I knew I couldn't be the only person in the world with this setup!

Thanks, Tom


If and only if Nest is now producing a thermostat that is designed specifically for in-floor heating. All thermostats and or controllers that control the water temperature that flows through the floor have a microprocessor and algorithms coupled with actual temperature sensors embedded right in the floor that will in real time design an on & off strategy or a mixing strategy that will heat the room adequately without over-heating the floor surface. This is a very sophisticated process.

The Nest thermostat as I understand it is really long on programming capability and the ability to control the heat from a remote location. It also works well with a home automation system. But this Nest thermostat simply will turn the heating system on and off. There is a whole other class of thermostat with a whole lot of other functionality that is required to control floor heating systems. Hope this helps.
