A Thermostatic Radiator Valve (TRV) automatically controls the temperature of a room by regulating hot water flow into a radiator. A Lockshield valve is used to balance the heating system by controlling the flow of water returning from the radiator, ensuring even heating across all radiators.
This LavaTherm Radiator Valve Twin Pack is designed for standard 15 mm UK central-heating pipework.
While the pack is supplied with everything needed for one radiator, installation involves working with your central heating system. It is strongly recommended that a qualified plumber carries out the installation to ensure safety and proper function.
The TRV head has numbered settings, typically from 0 to 5. Lower numbers (e.g., 1) correspond to lower temperatures, while higher numbers (e.g., 5) correspond to higher temperatures. Setting 0 usually turns the valve off, and a star setting may indicate frost protection.
Yes, by preventing overheating and ensuring your heating system runs more efficiently, the LavaTherm Radiator Valve Twin Pack can help reduce energy waste, potentially leading to lower heating bills compared to manual valves.
You may need to replace your radiator valves if they are old and inefficient, difficult to adjust, leaking, or if you are experiencing uneven heating across your radiators.
The LavaTherm Radiator Valve Twin Pack is available in several modern finishes, including Chrome, Black, Anthracite, and Brass, to match your radiator and home decor.
Ensure the central heating system is on and the boiler is functioning. Check that the TRV is not set to its lowest setting (frost protection) or turned off. Verify the lockshield valve is open. If the issue persists, the radiator may need bleeding or there could be a blockage.
Adjust the TRV setting to your desired temperature. For consistent heating, ensure the lockshield valve is correctly balanced. If a radiator is always too hot, the lockshield may be too open; if too cold, it may be too closed. Consult a professional for precise balancing.
Turn the TRV head to its maximum setting (5) and leave it for a few minutes. If it's still stuck, gently try to rotate the head manually. If it remains stuck, the internal pin may be obstructed, requiring professional attention.
Check that all connections are tight. If the leak is from the valve body or spindle, the valve may be faulty and require replacement by a qualified professional.
Compatibility: This valve set is designed for standard 15 mm UK central heating pipework. It is compatible with most radiators and boilers. Before installation, confirm your existing pipework is 15 mm. This pack includes both the TRV and the Lockshield valve needed for one radiator.
Installation: Installation typically involves shutting off the central heating system, draining the radiator and associated pipework, removing the old valves, and fitting the new TRV and Lockshield. It is recommended that installation is performed by a qualified plumber to ensure correct fitting and system integrity.
Care: To maintain performance, periodically check that the TRV head can move freely. If it feels stiff, gently try to rotate it. Clean the exterior of the valves with a soft, damp cloth. Avoid using abrasive cleaners or solvents, as these can damage the finish and components. Ensure the system is properly bled of air after installation or maintenance.
