The Elego Modern Thermostatic Radiator Valves (TRVs) are designed for homeowners looking to modernize their heating systems with a sleek, minimalist aesthetic without sacrificing efficiency. These valves provide precise temperature control, allowing users to tailor heat output to specific rooms, which helps optimize energy consumption and lower utility costs. While they offer excellent functional performance and include essential frost protection, potential buyers should note that these valves are not bi-directional, requiring careful attention to flow and return side placement during the installation process.

No, these valves are not bi-directional. You must install the thermostatic head on the flow side and the lockshield on the return side.
The frost protection setting automatically allows water to flow through the radiator when the room temperature dips below 7C to prevent the system from freezing.
Yes, each set includes one thermostatic valve and one lockshield valve, which is standard for one radiator installation.
No, these are designed specifically for water-based radiator systems.
Use a soft, damp cloth. Avoid using harsh chemicals or abrasive sponges to prevent damaging the grey finish.
The valve pin may be stuck due to inactivity. Remove the head and gently press the pin to ensure it moves freely, or check if the valve was installed on the wrong side (flow vs return).
Ensure that adequate PTFE tape was used on the threads and that all nuts are tightened securely to the radiator and pipework.
Verify that the thermostatic head is correctly positioned on the flow side of the radiator.
Proper installation is vital for the correct operation of the Elego TRVs. Because these valves are not bi-directional, you must ensure the thermostatic head is fitted to the flow side of the radiator, while the lockshield valve must be fitted to the return side. If reversed, the valve will not regulate heat effectively and may cause audible water hammer or inconsistent heating.
Before installation, ensure your existing heating system is drained down. Use PTFE tape on all threaded connections to prevent leaks. Once installed, avoid using harsh abrasive cleaners on the grey finish; a simple wipe with a soft, damp cloth is sufficient to keep the valves looking new. Regularly check the valve operation at the start of the heating season to ensure the internal pin has not seized during the summer months.
