The key benefit is automated room temperature control, leading to potential energy savings. A caveat is that installation requires basic plumbing knowledge or the assistance of a professional. This pack includes a Thermostatic Radiator Valve (TRV) and a Lockshield valve, essential components for regulating heat flow in standard 15 mm UK radiator systems. Features include automatic temperature adjustment via a liquid-sensor TRV and system balancing with the lockshield valve, ensuring consistent heat distribution.

FAQs

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

A Thermostatic Radiator Valve (TRV) automatically controls the temperature of a room by regulating the hot water flow into the radiator. A Lockshield valve is used on the radiator's outlet to balance the heating system, ensuring even heat distribution to all radiators.

Do I need to replace both valves on a radiator?

Yes, for optimal performance and control, it is recommended to replace both the TRV (on the inlet) and the Lockshield valve (on the outlet) when upgrading a radiator.

What size pipework is this valve compatible with?

This LavaTherm Radiator Valve Twin Pack is compatible with standard 15 mm UK central heating pipework.

How do I set the temperature on the TRV?

The TRV head typically has numbered settings (e.g., 1 to 5) corresponding to different temperature ranges. Higher numbers represent warmer settings. Consult the product manual for specific temperature equivalents for each setting.

Can I install this myself?

Installation requires basic plumbing knowledge, including draining the system and tightening connections. If you are not comfortable with these tasks, it is recommended to hire a qualified plumber for installation.

How can these valves save me money on heating bills?

By automatically maintaining your desired room temperature and ensuring your heating system is properly balanced, the TRVs prevent overheating and wasted energy. This efficient operation can lead to reduced energy consumption and lower heating costs.

What maintenance do these valves require?

Regular checks for leaks and cleaning with a damp cloth are recommended. The TRV pin may occasionally need gentle manipulation to ensure it moves freely. Avoid harsh chemicals or abrasive cleaning materials.

Troubleshooting

Radiator not heating up at all

Check if the heating system is on and the boiler is functioning. Ensure the TRV head is not set to the lowest '0' setting or 'frost' mode. Verify the lockshield valve is open. Check for any airlocks in the system and bleed the radiator if necessary.

Radiator is too hot and cannot be turned down

Ensure the TRV head is turned to the desired lower temperature setting. Check that the TRV pin (located under the head) is not stuck in the open position. If it is stuck, try gently tapping the pin or removing and reinstalling the TRV head.

Radiator is only warm at the top and cold at the bottom

This often indicates a need for system balancing. Adjust the lockshield valve to allow more return flow, or consult a professional to balance the entire heating system.

Leaking from valve connection

Ensure all connections are securely tightened. If leaking persists, the internal seals may be damaged, and the valve may need to be replaced.

TRV head is loose or spins freely

The TRV head may not be properly attached. Ensure it is securely clipped or screwed onto the valve body according to the manufacturer's instructions.

Pros and Cons

Pros

  • Provides both TRV and Lockshield valves for a complete setup.
  • Automated temperature control enhances comfort and reduces energy waste.
  • Improves system efficiency by balancing heat distribution.
  • Universal 15 mm compatibility for easy integration into most UK systems.
  • Available in various finishes to match home aesthetics.
  • Potential for lower heating bills due to energy efficiency.

Cons

  • Installation may require basic plumbing skills or professional help.
  • Only compatible with standard 15 mm UK pipework.
  • TRV settings require understanding for optimal energy saving.
  • The lockshield valve requires manual adjustment for balancing, which can be technical.

Setup, Compatibility & Care

Compatibility: This LavaTherm Radiator Valve Twin Pack is designed for standard 15 mm UK central heating pipework. It is compatible with most common radiators and boilers. Ensure your existing radiator has a standard 15 mm connection and that you have both an inlet (TRV) and an outlet (Lockshield) valve to replace or install.

Installation:

  1. Turn off your heating system and allow the system to cool down.
  2. Drain the radiator of water. You may need a radiator bleed key and a container to catch excess water.
  3. Remove the old TRV and Lockshield valve. Typically, these are unscrewed from the radiator body and pipework.
  4. Install the new LavaTherm TRV. Screw it onto the radiator inlet, ensuring it is correctly oriented (usually with the TRV head pointing upwards or outwards, depending on the model's specific requirements).
  5. Install the new LavaTherm Lockshield valve. Screw it onto the radiator outlet pipe.
  6. Turn on the heating system and check for leaks at both valve connections. Once the system is running, you may need to balance the radiators by adjusting the lockshield valve (consult a professional if unsure).

Care: To maintain the valves, periodically check for leaks. Gently clean the exterior with a soft, damp cloth. Avoid using abrasive cleaners. Ensure the TRV head can move freely; if it feels stiff, it may need gentle manipulation or lubrication (consult the manufacturer's guidelines).
