The best from Nest yet? It very well could be.

On Tuesday, Nest unveiled its third-generation Nest Learning Thermostat, revamped with a bigger, sharper display and sleeker design, and loaded with new features. The new unit can be ordered on the company's website now and it can be installed as soon as December for European customers.

With the revamped model, home owners can now control their hot water tank from the Nest Learning Thermostat, as the unit even comes equipped with an adjustable schedule for you, which can be manipulated via the company's app.

Within that function, owners can give weekend visitors extra shower time by giving their hot water a boost when needed — all from the comfort of the app. If you're on a vacation, the unit's auto-away feature turns off your hot water to conserve energy as well.

"The Nest Learning Thermostat is even better at learning about you and your home," the company boasts on its website. "It gets to know your schedule and the temperatures you like so it can program itself." 

The new Nest Thermostat uses OpenTherm technology, in which compatible boilers and the device communicate and work in unison to run the home's heating system more efficiently. Under the OpenTherm system, users can turn up the heat or dial it back a tad instead of simply turning it on and off, as most home owners do. Nest wants home owners to consider the feature as a dimmer for your heating system.

The amount of energy used daily can be seen within your Energy History log on the Nest app. Included in the app is also tips every month in your Home Report about how to help save energy even further.

The newest Nest Thermostat can be controlled from anywhere, whether your smartphone, laptop or tablet, and it works in sync with other Nest products.
