What is a thermostatic radiator valve (TRV)?
...an explanation for householders
TRVs sense the air temperature around them and
regulate the flow of water through the radiator which
they are fitted to. They do not control the boiler.
They should be set at a level that gives you the room
temperature you want. These settings may have to be
different in each room, and you should set the TRVs to
suit each room and then leave them to do their job.
Turning a TRV to a higher setting will not make the room
heat up any faster. How quickly the room heats up
depends on the boiler size and setting, and the radiator
size. Turning the TRV to a lower setting will result in the

room being controlled at a lower
temperature, and saves energy.
TRVs need a free flow of air to
sense the temperature, so they
must not be covered by curtains
or blocked by furniture.
TRVs cannot turn off the boiler when the whole house
is warm. To do that, you will need a room thermostat as
well. The radiator in the room with the room thermostat
should normally have a TRV, but, if it does, keep the
TRV on the maximum setting and adjust the room
thermostat as explained with the instructions.
