How does the 3rd-generation Nest Learning Thermostat save energy?
The Nest Learning Thermostat learns the temperatures that you like when you’re at home and then programs itself. It turns itself down when you’re away. That’s how it saves energy. And here’s the proof.
Most thermostats are programmable. They make you enter every temperature change that you want throughout the day or choose a start and stop time for heating your home. It’s annoying and complicated – many people don’t even bother.
How does learning make a difference?
No more programming. Just turn the Nest Thermostat up and down for the first few days after it’s been installed. It will get to know the temperatures that you like and when you like them. Then it programs itself. It even turns itself down when you’re away so that you’re not heating an empty home. The Nest Thermostat also learns about your home and figures out how it heats or cools, because no two homes are exactly the same. And it considers the outside weather conditions. So, it can figure out when to turn on the heating to get your home to the temperature you want without wasting energy, or when to turn the temperature down to prevent overshooting.
The Nest Thermostat also shows you how to save energy. Each time you adjust your thermostat to an energy-efficient temperature, you’ll see the Nest Leaf. Over time, it becomes harder to get the Leaf, encouraging you to save even more energy. Then you can check your Energy History on the Nest app to see how much you use every day and what has caused any big changes in your energy use. Nest also sends you a monthly Home Report so that you can compare how much energy you’re using this month versus last month. As you learn more about how and why you save energy, you can make simple changes to be more efficient.
