Smart Home Energy 
If you've got a compatible boiler and want heating that adapts to your life without fiddling with timers, the Nest Learning Thermostat programs itself by watching when you're home — but you'll need an installer and possibly a C-wire adapter.
Problem it solves
Reduces heating bills by learning your schedule and automatically adjusting temperatures, and allowing remote control via app to avoid heating an empty home.
Who it's for
Homeowners with compatible heating systems (combi or system boilers, OpenTherm-compatible) who want automatic scheduling without manual programming.
Why we recommend
Nest is the top of the range smart thermostat for those that don't mind the high price point and want a cool looking device.
