Your thermostat controls 60% of your energy bill. So shouldn’t it help you save energy? The Nest Thermostat does. Since 2011, it’s saved over 8 billion kWh of energy in millions of homes worldwide. Because it learns from you. It gets to know the temperature you like when 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 it needs. That’s how the Nest Thermostat saves energy. Your life with Nest. The Nest Thermostat automatically adapts as your life changes. Just use it for a week and it programs itself. Control your hot water. Now, you can control your hot water tank with the Nest Thermostat. It comes with a hot water schedule – just adjust it from the Nest app. You can boost the heat so that you have extra hot water if you want it. And when you’re away from home for a few days, you don’t have to remember to turn off the hot water. The Nest Thermostat will do it for you. See how much you've saved. Nest shows you how much energy you use every day in Energy History, and every month in your Home Report. So you can see when you use more energy, such as at the weekend or Monday nights, and how to use less.
