Why Thermostatic radiator valves are a must-have!

What thermostatic radiator valves really do?

A thermostatic radiator valve is a self-regulating valve fitted to a heating system radiator, to control the temperature of a room by changing the flow of hot water to the radiator, this is normally carried out by turning a dial on the side of each radiator between 0-6 (see table below for valve settings).

How do they work?

New Drayton Radiator Valve - Heating - Bridgwater - TauntonThe classic thermostatic radiator valve contains a plug, typically made of wax (forming a wax motor), which expands or contracts with the surrounding air temperature. This plug is connected to a pin which in turn is connected to a valve. The valve gradually closes as the air temperature of the surrounding area increases, limiting the amount of water entering the radiator. This allows a maximum and minimum temperature to be set for each room depending on your personal preference, effectively each room then dictates its own temperature zone.

Problems to look out for!

The TRVs works by sensing the temperature of the air surrounding it, it is important to ensure that they are not:

  • Covered by material such as curtains or radiator covers, this will affect the air temperature around the control head.
  • If the control head is removed from the valve or the control head becomes lose the radiator will always be hot.


Top tip-

Another possible issue is the possibility of the radiator valve pin becoming stuck in a certain position. This means that your valve is unable to open or close (depending on the room temperature). This is very common when they are turned down in the summer months. You do not need to turn them down in the warmer periods, just simply turn the heating programmer to “off”. To free up the control pin really is an easy fix, just remove the head of the valve and loosen the control pin manually with a pair of pliers. If this doesn’t work, you may need a replacement. Make certain you always purchase the best quality radiator valves you can afford.

Must not-

TRVs should not be installed in the same room where the boiler thermostat is installed, this will be more difficult if the thermostat is located on a movable stand, the reason for this is because the programmable room thermostat is the master control and will override any TRV.

Smart TRVs –

Such increased control allows even better energy savings. (link evo home) and (Worcester bosch) (blog link about smart heating controls)
