Thermostatic radiator valve (TRV) sense the air temperature around them. They work by regulating the flow of water through the radiator which they are fitted to. However, it is important to remember that they do not control the boiler. TRVs are beneficial in providing much more focused control within a room. Therefore, you can set each TRV to a temperature best suited to each room. This is greatly beneficial in saving energy, as it offers the user the flexibility to have varying temperatures in separate parts of the home, rather than wasting energy heating a room that may not be occupied.

They are provided with a regulating element which automatically controls the opening of the valve to keep ambient temperature of the room where they are installed constant at the set value. The number on the valve corresponds to a specific air temperature. Once you have selected a number, the thermostatic valve will maintain this temperature. This prevents unwanted temperature rises and achieves considerable savings.

• 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.
• These settings may have to be different in each room, and you should set the TRV s 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 a 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 need a free flow of air to sense the temperature. They should not be covered by curtains or blocked by furniture. Nearby sources of heat such as lamps could also stop them from working properly.

• All radiator and pipe work must be flushed thoroughly to prevent problems caused by weld beads, dirt or rust in the system.
• When converting old heating systems, a pipe line strainer is recommended.
• The radiator valve is installed in the supply pipe to the radiator with the flow in the direction of the arrow.
• Do not install the thermostatic operator until all building and decorating working has been completed.
• The radiator valve should be installed so that the valve spindle is in a horizontal position to ensure good circulation of ambient air around the thermostatic operator.
• Circulation of air around the thermostatic head is not hindered.
• The thermostatic head with built-in sensor may not be mounted vertically

• Investing in the correct heating controls not only has the advantage of saving on energy, but also making the home a much more comfortable and user-friendly place to live in. More people should become aware of the fact that turning down our thermostat just one degree will save us as much as 10% on the average hating bill.
• You should note that turning a TRV to a higher setting will not make the room heat up any faster. How quickly the room heats up will be largely dependent on a number of factors such as the boiler size and setting, and the radiator size. If you turn the TRV to a lower setting, it will result in the room being controlled at a lower temperature and you will save on energy.
