Underfloor Heating Thermostats
An underfloor heating thermostat controls the floor temperature and switches your heating on and off. Every electric underfloor heating system needs one. We sell four: the M1 dial, the M5 digital, the T5 touch screen and the Wi5 WiFi thermostat. Every one comes with a 10K floor sensor and fits a standard single gang back box at least 35mm deep.
Which underfloor heating thermostat do I need?
| Thermostat | How you set it | Sensors |
|---|---|---|
| M1 dial | Turn the dial. No timer. | Floor sensor |
| M5 digital | Push buttons, manual or basic programming | Air sensor and floor sensor |
| T5 touch screen | Touch screen, programmable | Air sensor and floor sensor |
| Wi5 WiFi | From your phone or tablet over WiFi, programmable (5+2, 6+1 or 7-day) | Air sensor and floor sensor |
M1 dial thermostat
The simplest of the four. You turn the dial to set the floor temperature and it switches the heating on and off from the floor sensor. There’s no timer, so it suits a room where you’d rather switch the heating on when you need it.
M5 digital thermostat
Our best value thermostat. Use the push buttons as a simple manual thermostat, or set basic programming so the heating comes on at the times you choose. It has a built-in air sensor as well as the floor sensor.
T5 touch screen thermostat
A programmable thermostat with a large, low-profile touch screen, so your heating can follow your daily routine, and you can still change the temperature by hand at a touch. Available in three colours.
Wi5 WiFi thermostat
Connects to your WiFi so you can control your underfloor heating from your phone or tablet, wherever you are, and it is fully programmable with 5+2, 6+1 or 7-day schedules. You can link several Wi5 thermostats to one or more devices to run different rooms as separate zones. Available in three colours.
Electric Underfloor Heating Thermostat Controllers
Take control of your heating with Living Heat thermostat controllers.
From simple manual thermostats to advanced digital and smart Wi-Fi stats, these controllers make managing your underfloor heating easy and efficient.
Smart Control, Convenience & Savings
With digital and smart thermostats, you can adjust temperatures remotely via your mobile or smart device.
Wireless models allow flexible placement anywhere in your home, and touchscreens provide an intuitive way to set schedules, create temperature zones, and monitor energy usage.
Intelligent heating ensures warmth only when needed, helping you save energy and reduce costs without compromising comfort.
Floor sensors
Every Living Heat thermostat comes with one 10K floor sensor, which measures the floor temperature so the thermostat can keep it steady and stop the floor overheating. It’s good practice to fit a spare floor sensor as a backup when the heating is set into the floor.
When you need a contactor
All our thermostats handle loads up to 16 amps (3,600 watts). If your heating draws more than 16 amps, a contactor is required. We offer a 25 amp contactor for loads up to 5.8kW and a 40 amp contactor for loads up to 9.2kW. Another option is to split the floor into zones, each with its own thermostat. Your electrician will tell you which you need.
Underfloor heating thermostat FAQs
Do I need a thermostat for electric underfloor heating?
Yes. Every system needs one. It controls the floor temperature and stops the heating running when it doesn’t need to. You can add one when you choose your heating mat.
Can I control my underfloor heating from my phone?
Yes, with the Wi5 WiFi thermostat. It connects to your WiFi and you control it from your phone or tablet using the Smart Life app.
Will the thermostat fit my back box?
All four fit a standard single gang back box that’s 35mm deep or deeper.
What’s the difference between the air sensor and the floor sensor?
The floor sensor sits in the floor and measures the floor temperature. The air sensor is built into the thermostat and measures the room. The M5, T5 and Wi5 have both. The M1 works from the floor sensor only.
Do I need an electrician to fit the thermostat?
Yes. A qualified electrician must make the connection and wire in the thermostat.
What if my heating is more than 16 amps?
You’ll need a contactor so the thermostat isn’t carrying the full load, or you can split the heating into zones with a thermostat each. Your electrician will advise.
