Are smart thermostats worth the investment?

Smart thermostats connect your heating system to the internet, allowing you to adjust things remotely by phone, tablet or other device. Their basic function is the same as a traditional thermostat – you can programme a schedule to suit your needs and set up a plan for when your heating comes on and turns off, plus the temperature setting – but it’s much easier to manage it all with a smart thermostat.

The real difference is the extensive additional functionality smart thermostats offer. They learn how your home heats up, the temperatures you prefer, and can detect open windows or unexpected draughts. Some even keep track of when you leave home or if you’re on your way back so they can adjust your heating accordingly.

Features vary by thermostat, but below is a brief explanation of each of the common ones:

  • Multizone

Allows you to add more thermostats so you can independently control the heating in different areas of your home.

  • Open window detection

Senses a sudden drop in temperature or humidity when a window is opened, and can notify you or turn off the heating.

  • Hot water control

Gives you greater control over your hot water, but only works with certain water tanks.

  • Geolocation/geofencing

Enables your smart thermostat to communicate with your smartphone when you enter or leave your home, and automatically turn itself on or off.

  • Temperature notification

Lets you know if the temperature inside your home gets too high or low, preventing you from wasting energy or returning to a freezing home.

  • Weather forecast

Takes current and forecast temperatures into account to heat your home to your desired temperature.

  • Frost protection

Stops your pipes from freezing by firing up the heating if the outside temperature drops below a certain limit.

  • Holiday mode

Automatically sets your heating to a low temperature or switches it off when you’re away. You can then advise when you’re back and what temperature it should return to.

Smart thermostats typically work with most boilers, including standard gas, oil and electric. As long as the system can be controlled by a regular thermostat or programmer, it should be OK. Most smart thermostats can also work with other home tech such as Amazon Echo or Google Home. Once connected, you’ll be able to ask Alexa or Google to increase or decrease the heating, or set it at a certain temperature. And there’s no need to worry if your internet connection goes down temporarily, your heating will stay on and continue to run the schedule you’ve set it to. You may not be able to update it via your app or online until things are back up and running, but you’ll still be able to use the manual controls on the thermostat itself if needed.

Smart thermostats cost anywhere between £150 and £280, depending on make and model, plus installation. There’s no guarantee you’ll save money though, it really depends on your habits. If you leave the house and return home at roughly the same times every day, a traditional thermostat would probably be sufficient, as they can be programmed to come on at set times. Similarly, if you work from home, you should be able to manage your heating manually. But if you don’t have a set routine, or you’re keen to get a better handle on your heating bills, a smart thermostat could be a great option for you and help you make sizable savings. And in contrast to smart meters, it doesn’t matter to smart thermostats which energy supplier you use, so you can switch as and when you find a better deal.
