Thermostatic radiator valves
Thermostatic radiator valves (TRV’s), allow you to control the temperature of each radiator in your home.
This allows you to save money on heating by turning radiators in hot rooms, or rooms you don’t use down or off.
Some rooms are naturally hotter than others, so they require less heat to get the room to your ideal temperature; this is where the TRV comes in.
Thermostatic Radiator Valve Information
You can fit a TRV yourself if you are comfortable draining down your heating system.
If you aren’t comfortable draining down your system or you think there would be a high chance of leaks if you did it yourself, get a plumber or heating engineer in.
Unfortunately, the answer to this question is no. Not all smart TRVs are compatible with all smart thermostats.
However, if you just want a regular TRV then they don’t need to connect to a smart thermostat and you can control the temperature by manually adjusting the dial on the TRV.
A regular TRV doesn’t have WiFi connectivity. It doesn’t connect to your smart thermostat or your smartphone. A smart TRV is connected to your smart home, so you can control the temperature in individual rooms using an app.
Regular TRVs still allow you to control the temperature of radiators in each room, but you have to go into that room to do it.
A wireless TRV is a cross between a smart TRV and a regular TRV.
It does connect to an app on your phone, giving you the ability to control the temperature without moving from your sofa but they don’t communicate with the smart thermostat, so they can’t tell the boiler to turn on.
Yes. TRV manufacturers have built TRVs to be a direct replacement for your old radiator valve.
If you’re replacing an older TRV for a new one, you may not need to drain your system down. It may just be a case of replacing the head, but check with the manufacturer first.
