Wondering which thermostatic radiator valve is the best to choose? In this guide we review and compare some of the UK's most popular options.
A Thermostatic Radiator Valve (TRV) is a regulating valve that helps you to control the temperature of individual radiators and therefore rooms or "zones" in your home.
It is often fitted to the side of the hot water heating system. It provides an easy and inexpensive solution to heating your property more efficiently.
TRVs provide a means of saving heat and reducing bills. They adjust the room temperature by controlling the amount of hot water entering the radiator.
When installed properly, you have a centralized boiler and differing levels of heating throughout the house, allowing you to take advantage of the concept of "Zonal Heating".
If you plan on installing one, here are our top picks for the best TRVs available in the UK.

Best Thermostatic Radiator Valves Ranked
So, without further ado, if you are looking to install a new TRV or replace an old one, here are our top 7 suggestions you must look at before making a final decision:
1. Tado Smart Thermostatic Radiator Valves
Our number one choice is the smart thermostatic radiator valves by the renowned German brand tado°.
In order to use and reap the full benefit of these, you will need to install the tado° smart thermostat device.
This will then allow you to adjust the thermostat on each of your radiators remotely or as part of the smart system's automated settings.
From the tado° app, you are then able to select the sensor within the room you wish to take lead for thermostatic control - i.e. so that the thermostat sensor can take the lead on regulating the heating in that room.
Utilising smart thermostats offers maximum convenience since it means you don't have to go around your house constantly adjusting each individual TRV.
It also means that your system can really take advantage of the concept of "zonal heating".
A zoned heating system enables you to control the temperature of each room or zone individually, thereby maximizing comfort and minimizing energy costs.

Can TRVs Be Installed On Old Radiators?
Yes, you can ideally install TRVs on all radiators, including old ones.
However, it is advisable to have one radiator without a TRV always turned on.
Ensure you don't have your TRV in the same room as your thermostat, as it may cause the system to malfunction.
How Does A TRV Work On A Radiator?
TRVs are self-regulating valves that adjust the flow of water that goes from the boiler to the radiator.
As the room warms up, the valve body closes, allowing less hot water into the radiator.
Then, as the space cools down, the valve body opens, allowing the influx of hot water once again.
What Is The Best Way To Use A Thermostatic Radiator Valve?
- Position the TRV where there is adequate air movement to ensure accurate air temperature detection
- Install the TRV on all radiators except in the room where the room thermostat is located
- Perform annual checks to clean dust and grime
- Use it in 2 or 3 sets
