The Nest thermostat and app haven’t officially launched yet in the UK but a launch is apparently imminent. The thermostat has a beautiful design and simple interface and secondly is truely innovative.  Once installed it will begin to pick up the habits of the dwellers and when you are in or out of the house and adjust the heating accordingly. The app connects to the thermostat, allowing you to control it from out of the house.  The only issue with this product (apart from it not being released yet!) is that it is a little pricey, but that is fairly understandable being the first wifi enabled thermostat on the market. Conversely, the energy savings are reported to be about 10-25%, so it could be a worthwhile investment. Watch out for this one.
