The Best Smart Radiator Valves for Your Home

The Best Smart Radiator Valves for Your Home

Smart radiator valves are devices that are connected to your radiator and allow you to control the temperature of each individual radiator in your home. In this blog, we will explore what smart radiator valves are, the benefits of using them, and which smart radiator valve system is the best.

What are smart radiator valves?

Smart radiator valves connect to your home’s Wi-Fi network and allow you to control the temperature of each radiator via an app or other remote control. The valves work by regulating the amount of hot water that is allowed to flow through each radiator, which allows you to easily adjust the temperature of each room in your home.

Smart radiator valves also have other features and capabilities, such as being able to detect when a window is open and automatically shut off the heating in that room. You can set schedules for the radiator valves to control when each radiator is on or off so you don’t have to worry about manually adjusting your radiators every day.

Advantages of smart radiator valves

There are many benefits to using smart radiator valves, such as more accurate room-by-room heating control, energy savings, and convenience.

Smart radiator valves can help you save on energy costs by automatically adjusting the temperature to specific levels and even switching off a radiator when a room is unoccupied. You can also set schedules for the radiator valves to specify when each radiator will be on or off – and have different schedules for different days or months, or occupation patterns for example a ‘work day schedule’ and ‘weekend schedule’ so you don’t have to worry about manually adjusting the radiators.

Smart radiator valves also provide a very convenient way to control the temperature of each radiator from your smartphone or other remote control so you don’t have to work your way around the house to manually adjust the temperature of each radiator.

Are smart radiator valves worth it?

If you are looking for a simplified way to control the temperature of each room in your home independently, then smart radiator valves are a great option. But whether they’re truly worth the investment depends on why you want them and how you use them.

If you already have Thermostatic Radiator Valves (TRVs) which allow you to control the temperature of individual radiators manually, and you’re happy using these then it’s unlikely you’ll make additional financial savings from smart radiator valves.

Some brands of smart radiator valves claim that up to 30% savings on your heating bills are possible, which is way higher than the 10-12% savings that Nest claim you’ll achieve with their Learning Thermostat. But the 30% saving would be in an ideal case, the reality is likely to be lower.

If you think about it this makes sense. A smart thermostat will control your whole house’s heating, turning the heating up or down for all rooms at the same time. But, if used well, smart radiator valves should enable you to avoid heating some rooms completely some of the time, hence the larger savings.

So, whether smart radiator valves are worth it depends on their usage and how you program them. The vast proportion of the savings will come from not heating unused rooms, which you could achieve with regular TRVs anyway, if you’re happy to adjust them manually.

Environmentally, if your heating system runs on oil or gas there will definitely be come carbon savings but it takes energy to produce smart valves and you will create waste with the old valves you remove.

Do I need smart radiator valves on every radiator?

No, you don’t need to have smart radiator valves on every radiator. You can choose which radiators you want to have smart radiator valves installed on, depending on your individual requirements.
