What is a Thermostatic Radiator Valve?
A Thermostatic Radiator Valve, or TRV, is a device that can be fitted to your radiator to help regulate the flow of water from your boiler to your radiator.
How does a TRV work?
TRV’s contains sensors that measure the air temperature of the room where the radiator is fitted. When a room reaches the desired temperature the TRV will shut the radiator off so that no more hot water flows to it. When the temperature falls it will turn it on again.
The TRV is fitted to your pipework that leads into your radiator. A thermostatic head senses the air temperature around the unit and subsequently opens and closes a valve.
As the valve opens it allows more hot water from the boiler to flow into the radiator, enabling the radiator to output more heat. As the valve closes and water flow into the radiator is restricted the less heat it produces.
Will a TRV save me money?
TRVs are a simple and very cost-effective way to better manage your central heating and save money on heating bills by becoming more energy efficient.
Research performed at Salford University on behalf of BEAMA Heating Controls concluded that adding a room thermostat and TRVs to your central heating system could save up to 40%, most of the saving was attributed to TRVs.
Used in conjunction with other central heating devices such as room thermostats and timers, TRVs can substantially reduce your household energy consumption.
In addition to saving money, installing a TRV is an immediate and practical way to reduce your carbon footprint, a valuable contribution to helping climate change.
TRV hints and tips
- Twist the knob every so often to avoid the TRV sticking.
- Try not to bash them when vacuuming as a damaged TRV won’t give the correct readings.
- Try not to cover them with curtains or block them with furniture. A TRV needs a free flow of air to the sensor to read the correct room temperature
