This Elego Angled Thermostatic Radiator Valve (TRV) in Matte Black is for homeowners looking to upgrade their modern heated towel rails or radiators for precise temperature control and energy savings. Its key benefit is the ability to precisely adjust heat output per room, lowering heating costs and enhancing comfort. A caveat is that these valves are not bi-directional and require correct installation orientation. This guide covers its features, setup, use, and care.

A TRV is a temperature-sensing valve fitted to a radiator. It automatically adjusts the flow of hot water into the radiator to maintain a set room temperature, helping to save energy and improve comfort.
The TRV head contains the temperature sensor. It needs to be positioned on the flow pipe (where hot water enters the radiator) so it can accurately sense the room's temperature and control the water flow accordingly. The lockshield valve on the return side balances the system.
Installation requires basic plumbing knowledge, including identifying flow and return pipes and tightening compression fittings. If you are unsure, it is recommended to have them installed by a qualified professional to ensure correct operation and prevent leaks.
The TRV head has a dial, typically numbered from 0 to 5. Each number corresponds to an approximate room temperature: 0 (frost protection, approx. 7°C), 1 (approx. 12°C), 2 (approx. 16°C), 3 (approx. 20°C), 4 (approx. 24°C), 5 (maximum setting).
It means the valve must be installed in a specific orientation. The TRV head must go on the flow pipe, and the lockshield on the return pipe. Installing it the other way around will cause it to function incorrectly.
The valve body is constructed from solid brass for durability, while the TRV head is typically made from ABS with a premium finish.
To fully shut off the radiator, you need to close both the TRV head and the lockshield valve. Specific instructions for fully closing the TRV head can be found in the online user manual.
Ensure the TRV head is correctly installed on the flow side and the lockshield is on the return. Check that the central heating system is on and the boiler is functioning. Ensure the valve is not set to its lowest frost protection setting if the room is cold.
Verify the TRV head is installed on the flow pipe and the lockshield is on the return pipe. If installed incorrectly (TRV on return), it will bypass the thermostatic function. Re-install with correct orientation.
The TRV mechanism might be stiff. Try gently turning it back and forth through its full range. If it remains stuck, consult the user manual or a qualified professional.
Check the compression fittings for tightness. If the leak persists, the valve internal seals may be compromised. Contact customer support or a plumber.
Frost protection activates around 7°C. If ambient temperatures are significantly lower or the valve is not functioning correctly, ensure the system has adequate antifreeze or consult a heating engineer.
