How does a thermostatic radiator valve work?

TRVs consist of two main parts, a thermostatic head which senses the air temperature around them and the valve body, which together regulate the flow of water through the radiator which they are fitted to. Inside the thermostatic head is a sensor containing a wax or liquid material which expands as the room temperature warms up and contracts when it cools down. The sensor is connected, in turn, to a valve seat inside the body which opens as the sensor expands and closes as the sensor contracts. As the TRV opens to allow more hot water from the boiler though the radiator, more heat will be given out by the radiator. As the TRV closes and restricts the flow through the radiator, less heat will be given out by the radiator, however, please note that the TRV does not switch the boiler on / off, it only regulates the flow of the available hot water.
