How to Choose a Smart Thermostat

Check compatibility with your heating system

Most smart thermostats work with combi boilers, system boilers, and heat pumps, but not all support electric storage heaters or older systems. Check the manufacturer's compatibility tool before buying.

Consider the number of zones you need

If you want to control individual radiators, look for a system that supports multiple zone valves or smart radiator valves. Single-zone models are simpler for open-plan homes.

Look at the app and smart home integration

Choose a thermostat that works with your existing ecosystem, whether Google Home, Amazon Alexa, or Apple HomeKit. A good app should offer scheduling, geofencing, and energy reports.

Mistakes to avoid

  • Buying a thermostat that is not compatible with your boiler type
  • Ignoring the need for a common wire (C-wire) in some installations
  • Choosing a model without a physical dial if you prefer tactile controls
  • Forgetting to check if you need a separate hub or bridge
