Straight Thermostatic Radiator Valve 20mm x 3/4'' With PPR Pipe Nickel Plated

When the temperature of the room begins to change, a capsule in the head of the TRV will either expand or contract – automatically moving a pin in the body of the valve which causes the valve to either open or close.

If the temperature in your room drops a little too low, the capsule will contract and pull out the pin; allowing more hot water to enter your radiator and increase its temperature.

Conversely – if the room begins to get a little too warm – the expansion of the same capsule will cause the pin to close the valve and reduce the amount of hot water.

The capsules in thermostatic radiator valves operate using a metal spring that is filled with wax or liquid – with the liquid type considered to be the best and most consistent at adjusting the temperature.

One of the main advantages of liquid TRVs is that they are far more responsive to fluctuations in temperature than their wax cousins.

Wax can be quite slow to expand and contract, while liquid TRVs will change the flow of water into the radiator considerably more quickly – this is also reflecting in the price of both variations.
