Thermostatic Radiator Valves: How Do They Work?

Traditional Cast Iron Radiator valves made by Carron and Sold Worldwide by UKAA

A thermostatic radiator valve (TRV) is a self-regulating valve fitted to a hot water heating system radiator, used to control the temperature of a room by changing the flow of hot water to the radiator. The room temperature is set by twisting the thermostatic head. Thermostatic valves make a very popular choice, combining efficiency with style.

The classic radiator TRV contains a plug, typically made of wax (forming a wax motor), which expands or contracts with the surrounding temperature. This plug is connected to a pin which, in turn, is connected to a valve. The valve gradually closes as the temperature of the surrounding area increases, limiting the amount of hot water entering the radiator. This allows a maximum temperature to be set for each room.

As the thermostatic radiator valves fitting is designed to sense the temperature of the air surrounding it, it is important to ensure that it is not covered by material, such as curtains.

The replacement of a manual heating control with a radiator TRV has been estimated to save at least 280 kilograms (620 lb) CO2 per year. They are also considerably cost-efficient, using heat only when needed, and can reduce heating bills by up to 17% a year.

Most of the thermostatic radiator valves come with a radiator coupler ½” BSPT male thread. However, we can also supply some valves in ¾ inch BSPT male thread.

Building regulations state that new dwellings should be fitted with thermostatic valves.




Our range of thermostatic radiator valves are Faringdon, Crocus, Realm, Abbey, Gothic, Kingsgrove, Luxury & Bentley, which all come in a range of finishes.

Corner Radiator Valves

Corner radiator valves are also very popular choice for customers whose pipe work comes out of the wall and not the floor. Additionally, sleeve or shroud kits can also be used with corner radiator valves.

Manual Radiator Valves:

Manual radiator valves make a very popular choice as they combine ease and efficiency with style, making them a perfect complement to your cast iron radiator. With a manual radiator valve, they are either open or closed, and they will remain at the set temperature. You can also completely close a manual radiator valve, and there is no need to use a decorator’s cap.

Our range of Manual valves includes Faringdon, Brunel, Telford, Whitworth, Newton, Amberley, Milan, Carron Throttle, Crocus, Abbey Throttle, Abbey, Bradley, Daisy, Brumpton, Westminster. Additionally, our optional extras of sleeve or shroud kits also work with the manual radiator valves as well as corner radiator valves.

Please note, the following is to be read before fitting your radiator valves:

When screwing the valve tail into the bush, turn it finger tight. Next, using a spanner, turn it until there is only moderate resistance.

Please note that by using a 4” (100mm) spanner, it becomes difficult to over tighten.

It is easy to over tighten and crack the bush with an 8” spanner.

A thread sealant must be applied to the valve tail threads to get a water tight seal on the radiator valve cap.

Sealants are available from your plumbers – PTFE tape is an acceptable alternative.

It should not normally be necessary to unscrew the bushes, but if for any reason you do, retighten them gently, enough to create a good seal.

The torque from an 8” adjustable spanner is more than enough to create a good seal.

Please not, it is advised that 18” Stilsons should not be used when tightening radiator valve caps.

Decorator’s caps

Decorator's caps are used to fully isolate radiator TRV valves, whilst a radiator is removed for decorating.

These are available for our thermostatic radiator valves. Manual valves do not need decorator’s caps as they will turn completely off.

Decorators caps are available to fully close your cast iron radiator
