Lottery: Google Nest Thermostat

Google Nest Thermostat. Discover the 3rd generation Nest Learning Thermostat. It has new rings and a big, clear display. And it can control your hot water. Your thermostat controls more than half your energy bill. Shouldn't it help you save energy? The Nest Thermostat does. Since 2011, we estimate it has saved more than 39 billion kWh of energy in millions of homes around the world. Because it learns from you. It memorises the temperature you like to be at home. And it automatically lowers the temperature when you're away. It even learns how warm your home gets and if it's draughty so it only uses as much energy as it needs. That's how the Nest Thermostat helps you save energy. The Nest Thermostat automatically adapts to changes in your life. Just use it for a week and it will program itself automatically. The Nest Thermostat uses OpenTherm technology to modulate your compatible high-efficiency condensing boiler. It keeps your home at a constant temperature to keep you even more comfortable. Nest shows you how much energy you use every day in the Energy History, and every month in your Nest Report. So you can see when you use the most energy (for example, on weekends or Monday nights) and when you use the least.
