Smart thermostatic radiator valves (TRVs) are fitted to individual radiators of a property, allowing the user to control the temperature of that specific unit. Installing TRVs on all your radiators means you can control the temperature in each room. For example, during the day you might want the living room to be warm, but you don’t want the heating on in the bedrooms. Using TRVs in this way saves you energy and therefore money - benefitting both the environment and your wallet.
Installing TRVs in your home means you will no longer need the main thermostat - which once controlled the temperature across all your radiators.
You simply set each smart radiator valve to the temperature you want.
A smart TRV usually consists of:
- A display showing the temperature/target temperature/humidity
- Built-in thermometer
- Air humidity meter
- Manual operation dial
- Wireless communications system
Be aware that different TRVs have different functionalities, so be sure to select one that meets your needs.
What makes smart TRVs so special?
Regular TRVs require you to manually turn each valve to reflect the desired temperature. But smart valves let you control the radiator temperature remotely, usually via a smartphone app which uses Wi-Fi technology. The system comprises a smart thermostat which communicates with the smart radiator valves located on each radiator in your home.
Are smart TRVs easy to fit?
If your radiators are fitted with regular (manual) thermostatic valves, it should be a straightforward task to replace the valves with smart TRVs. You may consider swapping them out by yourself. However you may well prefer to hire a plumber to complete this task.
A reputable plumber will be required if you have older radiators with no TRVs of any kind.
Did you know?
- Some smart TRVs are so smart they know when you have left your home and will subsequently turn down your heating. This is made possible by something called 'geo-fencing' - a system that detects the GPS co-ordinates of your smartphone.
- Some smart TRVs use geo-fencing to know when you are moving back towards your home, turning up the heating for your arrival.
- Some smart TRVs can also detect a sudden drop in temperature, such as when a window or door is left open and can lower the heating in response - thereby saving you money.
Should I install smart TRVs in my home?
Smart TRVS make it easy to control the temperature in each room of your home. This control means you should save money, particularly by ensuring your heating is off when you’re not there. There will of course be some initial cost when you install this technology. The cheapest approach is to buy the smart TRVs and install them yourself. However, for most people it is easier to employ a professional plumber to do this. Installation costs are likely to be much smaller than the long-term savings you’ll enjoy - especially if you have a tendency to leave the heating on by mistake!
