Elego TRV Angled Thermostatic Radiator Valves - Silver

These valves are designed for use with modern hot water central heating systems that have standard 15mm pipework and 1/2 BSPT radiator connections. They are not suitable for steam or electric heating systems.

An angled valve is typically used when the radiator valve tails (where the pipes connect) are positioned at an angle to the pipework coming from the wall or floor. This is common for vertical radiators or some horizontal ones.

Installation requires draining the heating system and basic plumbing knowledge. While DIY installation is possible, it is recommended to consult the user manual and consider professional installation if you are unsure.

The temperature is set by rotating the thermostatic head. The numbers or symbols on the head correspond to different temperature settings. Lower numbers generally indicate lower temperatures. Refer to the user manual for specific temperature equivalents.

The lockshield valve is essential for balancing your heating system. Once the TRV is installed, the lockshield is adjusted to ensure water flows correctly through each radiator, preventing some radiators from being too hot while others are too cold.

These TRVs are not designed for complete shut-off by turning the head to a zero setting. For full isolation, you typically need to close both the TRV (by setting it to the lowest frost protection level) and the lockshield valve. For definitive instructions, please consult the specific online user manual provided by Elego.

The frost protection setting is designed to prevent your pipes and radiators from freezing. When the ambient room temperature drops below approximately 7°C, the valve will automatically open slightly to allow a small flow of warm water, preventing the system from freezing.

Ensure the thermostatic head is not set to the lowest frost protection setting or fully shut off. Check that the lockshield valve is open. Verify correct installation with the TRV head on the flow pipe.

Ensure the thermostatic head is clean and free from debris. Check that the room temperature is below the set temperature on the TRV. Confirm the valve is not stuck in an open position.

Gently try to rotate the head. If it remains stiff, it may require professional attention. Ensure it's not cross-threaded.

Turn off the water supply, drain the system, and carefully re-tighten the compression fittings. If the leak persists, the seal may be compromised, and the valve or fitting may need replacement.

Ensure the TRV is correctly installed on the flow pipe and is set to a temperature above the frost setting (7°C). Check that the lockshield valve is open. Significant system issues might require professional inspection.
