Smart thermostats have become a central element in modern smart homes, offering a convenient way to manage heating remotely and efficiently. They learn your habits and adjust temperatures accordingly, potentially saving money on energy bills and improving comfort. These devices connect to your Wi-Fi network and come with apps that allow scheduling, geofencing, and integration with other smart home products.
Economy 7 tariffs are a popular electricity pricing option in the UK, designed for homes that use most of their power during cheap, off-peak night hours. A smart thermostat compatible with Economy 7 can intelligently switch heating to run more during these cheaper times and reduce daytime consumption. This optimisation helps maximise your savings while maintaining comfortable temperatures throughout the day.
When choosing a smart thermostat for use with Economy 7, it is important to ensure it supports time-of-use tariffs and allows scheduling around your specific off-peak hours. Compatibility with your heating system, ease of use, and reliable connectivity are also key factors. We tested various smart thermostats that work with Economy 7 tariffs to identify which ones deliver both savings and simplicity.
