To control your heating from your phone on a room-by-room basis, you'll need a smart radiator valve (thermostatic radiator valve or TRV). Here are our recommendations.

There’s a reason smart heating is growing in popularity. Not only will it give you more control over the temperature in your home – so it’s always warm when you want it to be – but you can easily monitor your heat and potentially make savings on your energy bills. Still, we’d advise that you take manufacturers’ money-saving claims with a pinch of salt.

If you’re buying an entire smart heating system, it’ll take some time to recoup the cost of the tech but a smart radiator valve is a much smaller investment. Each one will allow you to control a single room, which means you can schedule heating so that it’s warm when it needs to be and no heat is wasted the rest of the time.

Being able to see the temperature clearly on your phone screen or on the device itself, instead of crawling around trying to decipher the lines on a standard radiator valve, gives you much more control over the heat output. Plus, many smart TRVs allow you to use voice control, via your Alexa or Google Assistant.

They’re also a great option for people in rented accommodation, or those who don’t want to get a full smart home heating system installed.
