The G-Rad Thermostatic Radiator Valve and Lockshield set is an ideal choice for homeowners and interior designers looking to pair functionality with a sleek, contemporary grey aesthetic for designer radiators or heated towel rails. It offers the benefit of precise, energy-efficient temperature regulation via an integrated sensor, though users should ensure their pipework diameter is compatible with the standard 15mm fitting before purchase.

No, this set is specifically designed for 15mm pipework and will not fit 10mm or 22mm systems without additional adapters.
While it is possible for those with plumbing experience, we recommend a qualified professional to ensure all connections are leak-proof.
A bi-directional valve allows for more flexibility during installation, as it can be fitted to either the flow or return side of the radiator.
Yes, the G-Rad set includes one thermostatic radiator valve and one matching lockshield.
Use a soft cloth with a mild detergent if necessary, ensuring it is dried thoroughly afterward. Avoid abrasive chemicals.
Check that the thermostatic head is not set to the lowest position or frozen. Ensure the pin beneath the head is not stuck by gently pressing it to verify it moves freely.
Ensure that the compression fitting is fully tightened and that the olive has been seated correctly during installation.
Verify that the thermostatic sensor is not obstructed by furniture or curtains, which can trap heat and cause the sensor to shut off prematurely.
Installation should be performed by a qualified plumber to ensure all seals are pressure-tested and secure. The valve is designed for 15mm pipework; verify your existing infrastructure before beginning the swap. Because the valve body is bi-directional, it can be mounted on either the flow or return pipe of the radiator without sacrificing efficiency. For routine care, wipe the valves down with a soft, dry or slightly damp lint-free cloth to maintain the grey finish. Avoid using harsh chemical cleaners or abrasive scouring pads, as these can damage the aesthetic coating over time.
