What is a TRV
A Thermostatic Radiator Valve (TRV) is an automated valve installed on a radiator within a central heating system, responsible for regulating the room’s air temperature by controlling the heat output of a radiator.
Comprising two key parts, the TRV includes the valve itself and a thermostat. The thermostat, equipped with a wax, liquid or gas-filled actuator, operates the valve cone, to either open or close the valves while sensing changes in room air temperature. Typically, a classic TRV incorporates a liquid plug that expands or contracts with temperature changes.
With rising room temperatures, the valve gradually closes over a period of time, wax sensors typically take around 40 minutes to close and liquid sensors 20 minutes, where gas-filled sensors are more responsive and close within 10 minutes. Users can manually set their preferred room temperature from between 8° and 28°C by adjusting the thermostat dial.
It's essential to maintain unobstructed airflow around a thermostatic radiator valve (TRV) to ensure its effective operation. Any blockage, whether from sofas, curtains, or draughts, can disrupt the TRV's ability to accurately gauge the room temperature, leading to inefficient heating. Keeping the area surrounding the TRV clear is vital for preserving its proper functionality.
What are the benefits of using TRV’s.
Thermostatic radiator valves (TRVs) offer several benefits that enhance both comfort and efficiency of heating systems in homes and buildings.
Individual room temperature control: TRVs allow for the setting and adjustment of temperatures in each room, for example enabling lower heating in bedrooms at 18 degrees and increased temperature in bathrooms at 24 degrees.
Prevention of overheating: By automatically shutting off the radiator when the room receives additional heat gain, such a solar.
Flexibility. The ease of adjustment of the valve provides the flexibility to adjust the room temperature according to use.
Cost-Savings: The correct use of the TRV and continued use over time has been shown to significantly reduce energy bills, with a potential saving of up to 40%
