FAQs

What is the difference between a TRV and a Lockshield valve?

A TRV (Thermostatic Radiator Valve) automatically controls the room temperature by regulating hot water flow into the radiator. A Lockshield valve is used to balance the heating system by controlling the water flow returning from the radiator, ensuring even heat distribution across all radiators.

Do I need to replace both valves on a radiator?

Yes, for optimal control and system balancing, both a TRV and a Lockshield valve are recommended for each radiator. This twin pack provides both necessary valves.

What size pipework is this valve compatible with?

The LavaTherm Radiator Valve Twin Pack is designed for standard 15 mm UK central heating pipework.

Can I install these valves myself?

If you have basic plumbing experience and the necessary tools, DIY installation is possible. However, if you are unsure, it is recommended to hire a qualified plumber to ensure correct installation and system balancing.

How do I set the TRV to save energy?

Set the TRV to the lowest temperature setting that keeps the room comfortable. For example, if '3' is comfortable, there's no need to set it higher. In unused rooms, set it to the 'snowflake' symbol or lowest setting to prevent the radiator from freezing.

How do I balance my heating system with the Lockshield valve?

Balancing involves adjusting the Lockshield valve to ensure all radiators heat up evenly. Typically, you adjust it so that radiators furthest from the boiler heat up first, and those closer heat up last. This process can be complex and often requires professional expertise for best results.

How do I clean the radiator valves?

Wipe the valves with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaning materials, as these can damage the finish or internal components.

Troubleshooting

Radiator not heating up at all.

Ensure the TRV is not set to the lowest setting (usually '0' or snowflake symbol). Check that the heating system is on and water is circulating. Verify the Lockshield valve is open.

Radiator overheating or too hot.

Adjust the TRV setting to a lower number. Ensure the Lockshield valve is correctly set to balance the system. Check for blockages in the radiator or pipework.

Valve is leaking.

Check that all connections are securely tightened. If the leak persists, the valve may need to be replaced.

TRV head is loose or wobbly.

Ensure the locking nut or collar securing the TRV head to the valve body is tightened.

Heating system is noisy.

Ensure the Lockshield valve is correctly balanced. Air in the system can also cause noise; bleed radiators as necessary.

Cons

  • Requires basic plumbing knowledge for installation, or professional help.
  • TRV settings may need occasional adjustment for optimal performance in different rooms.

Setup, Compatibility & Care

Compatibility:

  • The LavaTherm Radiator Valve Twin Pack is designed for standard 15 mm UK central heating pipework.
  • It is compatible with most radiators and boilers commonly found in UK homes.
  • Ensure your existing radiator connections are 15 mm to confirm compatibility.

Installation:

  1. Turn off the heating system and allow the radiators to cool completely.
  2. Drain water from the radiator you are working on. Place a towel or container to catch any residual water.
  3. Remove the old TRV and Lockshield valve from the radiator.
  4. Install the new LavaTherm TRV on the radiator inlet pipe, ensuring the flow direction arrow on the valve body points towards the radiator.
  5. Install the new LavaTherm Lockshield valve on the radiator outlet pipe.
  6. Tighten all connections securely but do not overtighten.
  7. Turn the heating system back on and check for any leaks. Bleed the radiator if necessary.
  8. Balance the system: Adjust the Lockshield valve to ensure even heating across all radiators. This may require professional guidance for optimal results.

Care:

  • Clean the valves with a soft, damp cloth. Avoid using abrasive cleaners or solvents.
  • Periodically check for leaks around the valve connections.
