Extended Product Information

FAQs

Are these valves compatible with all radiators?

These are designed for standard 15mm radiator inlets. Please verify your pipe diameter before purchase.

What is the purpose of the lockshield valve?

The lockshield is used to balance the system, controlling the return flow of water to ensure even heat distribution across all radiators.

Can I install these myself?

Installation involves draining your heating system. If you are not comfortable with plumbing, it is recommended to hire a professional.

How do I maintain the grey finish?

Use a soft, slightly damp cloth to wipe the surface. Avoid abrasive sponges or strong cleaning agents.

Does the set include everything needed for one radiator?

Yes, it includes both the thermostatic radiator valve and the lockshield, which is the standard requirement for one radiator.

Will this work on a 10mm pipe?

No, this specific model is designed for 15mm pipework. You would need a 15mm to 10mm reducer if your pipes are 10mm.

Troubleshooting

Radiator stays cold despite TRV being open

The valve pin may be stuck. Remove the head, gently press the pin down, and ensure it springs back up.

Water leaking from the valve connection

Ensure the pipe nut is tightened correctly and check that sufficient PTFE tape was applied to the threads.

Radiator gets too hot and doesn't regulate

Check that the TRV head is correctly seated and not blocked by curtains or furniture which can interfere with temperature sensing.

Setup, Compatibility & Care

Installation of the Stirling Bold set should be performed when the central heating system is turned off and the pipes have been drained. Ensure you have the correct 15mm pipe fittings before starting.

  1. Drain the radiator to prevent water damage during the swap.
  2. Remove the old valve and lockshield using appropriate spanners.
  3. Apply PTFE tape to the threads to ensure a watertight seal.
  4. Attach the new Stirling Bold valves, ensuring they are tightened securely but not over-torqued.
  5. Refill your system and check for leaks at all connection points.

For maintenance, clean the valve body periodically with a soft, damp cloth. Avoid harsh chemical cleaners as they may damage the grey finish.
