The Nest Thermostat learns your routines, so it can know when you need your heating to warm up to a comfortable temperature, and when to conserve energy to save you money on your heating bills. It does this by learning patterns and combining this with Geo location data. The thermostat will know when you are not at home, and turn the heating down to conserve energy. You are also able to set nighttime routines so the heating is turned down at night. In addition to this, if you turn the heating up at the same time a few days in a row, it will remember this, and begin to do this automatically for you.

The Nest Thermostat not only claims energy savings, it also provides detailed reports to show you when and how your energy has been saved. Providing daily and monthly details, and showing whether energy has been saved by schedules or when no one is home.

The Nest Thermostat not only manages your central heating system, but can also manage when your hot water is heated, saving additional energy by not heating your hot water when no one is home, and automatically switching it on when you are returning home and it will be needed.
