It is compatible with all standard heating systems using 15mm pipework, provided the pipework layout allows for a corner-style valve connection.
While technically possible for experienced DIYers, it involves draining your central heating system, so professional installation is highly recommended to avoid leaks.
The lockshield is used to balance your heating system by restricting the flow of water out of the radiator, ensuring all radiators in the house heat up evenly.
No, this is a mechanical thermostatic valve that uses a wax or liquid sensor to react to changes in ambient room temperature.
Use a soft, dry or slightly damp cloth to wipe the surface. Avoid chemical cleaners that could damage the grey finish.
It means the valve is engineered for pipework that comes out of the wall at a right angle, allowing the valve head to face outward for easier access.
Check if the thermostatic pin has become stuck due to inactivity; remove the head and gently depress the pin to ensure it moves freely.
Verify that the valve is not blocked by curtains or furniture, which can trap heat around the sensor and provide false temperature readings.
Ensure that sufficient PTFE tape or appropriate jointing compound was used during installation and that the compression nut is tightened correctly.
This set includes both the thermostatic valve and the matching lockshield. It is compatible with all standard domestic central heating systems using 15mm pipework. Installation should be performed by a qualified plumber, as it requires isolating the heating system and draining the radiator to prevent leaks. Once installed, the valve requires minimal maintenance. To keep the finish looking its best, wipe the surface periodically with a soft, damp cloth. Avoid using harsh chemical cleaners or abrasive scouring pads, as these can strip the grey coating or cause micro-scratches.
