Thermostatic Radiator Valves (TRVs)
Your radiators may be fitted with a
Thermostatic Radiator Valve. These work by sensing the air
temperature in the room and adjusting the heat accordingly.
A TRV is different to a room thermostat. A
room thermostat determines the maximum temperature for the house
and the TRV lets you vary this temperature room by room, meaning
you don't have to waste money warming rooms you seldom use. The
number on the valve corresponds to a specific air
temperature. Once you have selected a number, the
thermostatic valve will maintain this temperature
Some things to remember when using
If you turn a TRV down to low in a room, keep the door to that
room closed. This will reduce condensation and prevent the
radiators in other rooms from working overtime trying to heat the
air in there too.
The radiator will not be
hot all the time. The purpose of the valve is to allow you to
control the temperature in individual rooms. It turns the hot water
flow off when the room reaches the set temperature. Before you ring
to report a radiator that is not working, check that the TRV isn’t
set too low.
