Thermostatic radiator valves |
||||
 |
Thermostatic radiator valves, known as TRVs, cut off the flow of water to a radiator automatically when a set maximum temperature has been reached. | |||
 |
They turn the flow of water back on again when the radiator begins to cool. | |||
 |
They are available in many sizes and configurations – straight, vertical angle and horizontal angle – to suit various situations. | |||
 |
The temperature is set on a dial on the thermostat. | |||
 |
The automatic switching off of individual radiators can save money on your heating bills. | |||
Manual radiator valves |
||||
 |
A manual radiator valve has to be turned on and off by hand. | |||
 |
Most central heating systems have at least one radiator fitted with a manual valve.
This is to ensure there is still somewhere for the hot water to flow to and from if all the thermostatic valves are off at the same time. |
