11% Off

Why We Love It

Saves energy effectively.
Smart temperature scheduling.
Remote control convenience.

Main Highlights

Saving energy starts with your thermostat. Your thermostat controls 60% of your energy bill. So shouldn’t it help you save energy? The Nest Learning Thermostat does. Since 2011, it’s saved over 4 billion kWh of energy in millions of homes worldwide*. Because it learns from you. It gets to know the temperature that you like while you’re at home. And turns itself down when you’re away. It even learns how your home warms up or how draughty it is, so it only uses the energy that it needs
Auto-Schedule. Just turn it up and down. It learns the temperatures that you like and creates a schedule for you
Home/Away Assist. It automatically adjusts the temperature after you’ve left. It can even turn off your hot water if you’re away for a few days
Hot water. Now you can control your hot water tank. And give your hot water a boost when you need it
OpenTherm technology. Nest now uses OpenTherm technology to modulate your high-efficiency condensing boiler
Remote control. Change the temperature and control your hot water tank from anywhere using your mobile, tablet or laptop
Farsight. When the Nest Thermostat spots you across the room, it lights up beautifully to show you the time, temperature or weather
Pro install. The Nest Thermostat should be installed by a Nest Pro who will make sure that it’s in the right location, connect the Heat Link and set it up for you. Find a local pro at nest.com/eu/install
Better together. The Nest Thermostat works with Nest Protect. If Nest Protect detects dangerous carbon monoxide gas, it can tell the Nest Thermostat to turn off the boiler - a common source of CO leaks
