This guide is for homeowners looking to improve heating efficiency and comfort. The Elego Thermostatic Radiator Valves (TRVs) offer precise temperature control, leading to potential energy savings. A key consideration is their non-bi-directional design, requiring correct installation on the flow and return sides. These valves feature a sleek, modern aesthetic and are built from durable brass, offering a stylish upgrade for contemporary radiators and heated towel rails.

A TRV is a device fitted to a radiator that allows you to control the temperature of individual rooms. It automatically adjusts the hot water flow into the radiator to maintain a set temperature, helping to save energy and improve comfort.
The TRV head needs to sense the room's ambient temperature. The flow pipe carries hot water into the radiator, so placing the TRV head on this side allows it to accurately measure the room's temperature and regulate the heat output accordingly. Placing it on the return (cold) side would lead to inaccurate readings and poor performance.
The TRV head typically has a dial with numbers (e.g., 1-5). These numbers correspond to approximate room temperatures. Setting it to '3' might equate to around 20°C, but this can vary. Consult the user manual for specific temperature settings or experiment to find your preferred comfort level.
Frost protection is a setting (often indicated by a snowflake symbol or a very low number) that prevents your heating system from freezing in cold weather. When the room temperature drops below approximately 7°C, the TRV will automatically open slightly to allow a small amount of hot water to circulate, preventing pipes from freezing and potentially bursting.
While basic DIY installation is possible for those comfortable with plumbing, it's recommended to consult the user manual. Incorrect installation, particularly regarding the flow and return sides, can lead to inefficiency. If unsure, hiring a qualified plumber is advised.
A manual valve requires you to turn it on or off by hand and has no temperature regulation. A TRV, however, automatically regulates the temperature by opening and closing based on the room's ambient temperature and your set preference, offering better efficiency and comfort.
To fully shut off the valve, please consult the online user manual. The process typically involves turning the TRV head to the lowest setting or a specific 'off' position, but it's best to follow the manufacturer's precise instructions to ensure it's properly closed.
Ensure the TRV head is not set to the lowest 'frost protection' setting or fully closed. Check that the lockshield valve is fully open. Verify that the TRV is installed on the flow pipe.
Confirm the TRV head is correctly installed on the flow side. The lockshield valve may be fully open; try partially closing it. Ensure the TRV is not faulty; consult the user manual or consider replacement.
Gently try to turn the head. If it remains stiff, carefully remove the head (refer to user manual) and check for any obstructions. If still stiff, a replacement may be needed.
Check that all compression fittings are securely tightened. If leaks persist, ensure pipework is clean and not damaged. You may need to re-apply PTFE tape or sealant to the threads.
Ensure the heating system has been properly refilled and all air has been bled from the radiators, including the one with the new TRV.
Compatibility: These TRVs are designed for modern heated towel rails and radiators. They feature 15mm compression inlets and a 1/2 BSPT radiator coupler, making them compatible with standard 15mm pipework. Ensure your existing radiator valve tails are suitable for compression fittings.
Installation: Important: These valves are not bi-directional. The TRV thermostatic head must be installed on the flow side of the radiator, and the lockshield valve must be installed on the return side. Incorrect installation will impair performance.
Care: Wipe the valve body and thermostatic head with a soft, damp cloth. Avoid using abrasive cleaners or solvents. Periodically check for leaks and ensure the TRV head can still be turned freely.
