What is a TRV?

A thermostatic radiator valve (TRV) is a device that is installed onto a radiator to control the temperature of a room. It works by sensing the temperature of the air around it and adjusting the flow of hot water into the radiator accordingly.

TRVs consist of a valve body and a thermostatic head. The head contains a sensor that detects the temperature of the air around it. When the temperature drops below the set point, the head opens the valve, allowing hot water to flow into the radiator. As the temperature rises, the head closes the valve, reducing the flow of hot water.

TRVs are an effective way to control the temperature of a room, as they allow each radiator to be adjusted individually. This means that rooms that are used less frequently can be kept cooler, while rooms that are used more frequently can be kept warmer. This can help to reduce energy consumption and lower heating bills.

In addition to their energy-saving benefits, TRVs are also easy to install and use. They can be fitted to most radiators, and once installed, they can be adjusted using a simple dial or digital display.
