The best smart thermostat: control your heating and hot water from your phone

Ensure you always come home to the perfect temperature with our list of the best smart thermostats

TODO alt text

Rethinking your home's heating system? Smart thermostats not only enable you to control your boiler from wherever you happen to be in the country. Many also enable you to change your hot water timings and adjust your underfloor heating settings, too. They’re a great way for you to save on your energy bills; if plans change and you’re no longer going to be home for seven o’clock, you can tap into the app and delay the timer, so you’re not wasting money by heating your home unnecessarily.  

There are some pretty intelligent thermostats out there, with the Nest Learning Thermostat getting the most points for its ability to control your boiler, underfloor heating and your hot water. 

As the most expensive smart thermostat on the list, the Honeywell Evohome enables you to individually control the temperature of each room in the house, so if one family member likes their room warm and the other their room cool, this smart thermostat has you covered.
