There are numerous smart thermostats to choose from, each offering a variety of features, so it’s important to pick the one that suits your lifestyle and home. First, you need to consider the type of heating system you want. A regular smart thermostat simply replaces your existing thermostat. You’ll still save money with such a system, but your heating settings will be applied to your entire home. A zoned heating system offers room-by-room control via smart thermostatic radiator valves (TRVs). Such a system will save you more money since you’ll be heating only the areas you’re using at any given time. The downside is that the initial outlay for such systems can be costly: typically around £50 to £70 per radiator. They’re a better option for houses with a greater number of rooms.
