Smart thermostats are part of a range of smart home gadgets that can help you control your home's energy usage - here's how

What is a smart thermostat?

A smart thermostat is a type of thermostat that lets you control your home’s heating remotely, via devices like smartphones and tablets.

What can smart thermostats do?

Your smart thermostat’s functionality will depend on the make and model you buy, and how much you’re willing to spend. Some of the most useful features include:

  • Voice control: So you can command your central heating from the comfort of your sofa
  • Temperature alerts: To warn you if the temperature poses a threat to your water pipes
  • Zoned heating: Multi-room or multi-zone control, letting you heat different parts of your home independently.
  • Geo-fencing: Recognises when you’ve entered or left your home, and adjusts temperature accordingly
  • Link up with other smart technology: Such as Alexa, Google Home, or other devices to make your home truly smart
  • Learning capabilities: Some smart thermostats can learn how long it takes to heat each room in your home and then then check the weather report, to ensure optimal energy-efficient heating
  • Holiday mode: To keep your home just warm enough to prevent pipes freezing if you are away
  • Hot water settings: Allows you to control your hot water, but you might need additional kit for this functionality

What are the benefits of a smart thermostat?

Not only does a smart thermostat have the potential to save you money on your energy bills, but they are extremely convenient, allowing you to control your home’s heating from wherever you are.

How much do smart thermostats cost?

Smart thermostats typically cost between £150 and £280, depending on the make and model. Most makers recommend getting them professionally installed – which usually costs an additional £50 to £100.

If you want zoned heating, smart thermostatic radiator valves will need to be fitted to each radiator to control them individually – these can be around £60 each.

What is the difference between smart thermostats and smart meters?

Smart thermostats may seem similar to smart meters, but they work quite differently:

  • A smart meter shows you information about your energy usage and costs, generally on a display inside your home
  • A smart thermostat lets you control your home’s heating

Can smart thermostats help you save money?

Installing a smart thermostat could help you save money, but it will also depend on your energy habits.

If you leave and enter your house at different times every day, a smart thermostat could be a good option for you. The same goes if you or someone else often forgets to turn off the heating before you leave – you’ll still be able to shut it down remotely from your phone or tablet.

If you have a set routine where you leave the house at the same time every day and return at the same time, it may not be as useful – you can already programme most thermostats to come on at specific times.

What if my internet goes down?

Smart thermostats use the internet to allow you to control you home’s heating remotely. If your internet were to go down, don’t worry, the heating will stay on and your smart thermostat system will usually continue to run your schedule.

You won’t be able to control it via the app or online, but you can adjust it via the thermostat’s manual controls if needed.
