OpenTherm Technology

Nest now uses OpenTherm technology to modulate your high-efficiency condensing boiler.


Nest learns the temperatures you like and programs itself in about a week.


Nest automatically turns itself down when nobody’s home to help you save energy.

Hot water control

Control your hot water tank from anywhere. Adjust your hot water schedule. And give your hot water a boost if you need it.

Remote control

Connect your thermostat to Wi‑Fi to control the temperature from your phone, tablet or laptop.

Nest Leaf

You’ll see the Leaf when you choose a temperature that saves energy. It guides you in the right direction.

Energy savings are not guaranteed and depend on energy usage, weather and other factors. Learn more

A Nest home.

When you add more Nest products to your home, they can automatically work together.
And you can control them all from one place: the Nest app.

If you have a Nest Cam, it can automatically turn on alerts when your Nest Thermostat is set to away.
If your Nest Protect senses smoke or carbon monoxide, your Nest Thermostat can display an alert. Your thermostat can also shut off the heating system to keep the danger from spreading.

There are a lot of products that work with Nest. Going on holiday? As soon as your Nest Thermostat switches itself into Away mode, LIFX can make it look as if someone is home by automatically turning your lights on and off throughout the house.
