Product description:

The Nest Learning Thermostat is a programmer, thermostat and frostat in one. It learns your schedule to programme itself, turns down the heat when you’re away, and can be controlled from your mobile phone. It shows you how much heat you’ve used over the last 10 days, and sends an Energy Report every month to help you track and manage your energy use. The Nest Learning Thermostat is compatible with many central heating systems, including:

  • Combi boilers
  • System and heat-only boilers
  • Domestic hot water tanks
  • Hydronic underfloor systems
  • Air source and ground source heat pumps (heating only)
