It is easy to brush off the importance of your thermostat. Sure, you use it to control your home’s temperature during the day and night, twiddling it a little here and there until you’re comfortable. But did you know that your thermostat controls up to half of your energy bill?

That’s right – solid temperature habits, like turning the temperature down while you are gone during the day, can save you up to half on your energy bill. Yet so many of us forget to do this in the hustle and bustle of our daily routines. And that is right where the Nest Learning Thermostat comes in. Its one-of-a-kind design makes it an even better choice – and an even better money saver – than the best programmable thermostats on the market.

This is because the Nest Thermostat actually learns about your family’s temperature habits every time you use it. Each time you adjust the temperature, the Nest takes note of the time, date, and type of adjustment, storing this data in its memory. After a week or two of use, you can leave your Nest Thermostat in control and it will adjust your home’s temperature to your ideal level by itself.

The Nest even differentiates between weekdays and weekends (heating the house up a little later if you like to sleep in on Saturdays, for example) and even programs itself to start heating or cooling depending on how long your heater or air conditioner takes to reach the target temperature. For instance, a radiant heating system that takes a while to raise the temperature will be turned on in advance so your home is exactly the temperature you want it to be exactly when you want it to be.

Beyond its learning function, the Nest scores big in several other areas. Chief among these is its design. The thermostat seriously looks more like the next big device from Apple than something that goes on your wall and controls your home’s temperature.

The folks at Nest threw out the button-clogged design of most modern thermostats in favor of a hockey-puck-shaped thermostat with a round screen that takes up the majority of the device. To adjust the temperature, you simply turn a ring going around the Nest. The screen lights up blue for cooling and red for heating (it also shows the temperature by number). And when you are making an energy-saving temperature choice, a nice little green leaf pops up to congratulate you.

Should you buy the Nest Thermostat?

Though the price of the Nest Thermostat (currently $250) can be a little difficult to stomach, it is worth every penny in the long run. The device enables you to save so much money on your monthly energy bills while keeping your family comfortable at the same time. And with easy installation, an intuitive design, and a great customer support staff, the Nest Thermostat doesn’t have much of a learning curve at all. You can even make temperature adjustments without getting out of bed with the Nest mobile app!
