Nest

Normally we wouldn’t get very excited about a new thermostat, but the Nest has been designed by two former Apple employees who were involved in the creation of the iPod and iPhone. The Nest learns your habits every time you adjust it and automatically heats your house to suit. It even lets you control the heating when you’re not in via the mobile app. The makers of the device claim that this smart heating can halve your fuel bills. It’s already available in the US, and we’ve been told it’s likely to land in the UK in 2013.
