FAQs

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

The TRV (Thermostatic Radiator Valve) controls the hot water entering the radiator based on room temperature. The Lockshield valve is used to balance the system by controlling the hot water leaving the radiator, ensuring even heating across all radiators.

Do I need to turn the TRV to '0' in summer?

Yes, setting the TRV to the lowest setting ('0' or frost protection) during warmer months prevents the valve from operating unnecessarily and protects it from seizing.

Can I install this myself?

The valves are designed for standard 15 mm pipes and can be installed by individuals with basic plumbing knowledge. If you are unsure, it is recommended to hire a qualified professional.

What pipe size does this valve set fit?

This twin pack is specifically designed for standard 15 mm UK central-heating pipework.

How do I know if my radiator needs this pack?

If your radiators have old manual valves or if you are experiencing uneven heating, this twin pack is an ideal upgrade. It provides one TRV and one lockshield for each radiator.

Will this save me money on my heating bills?

By providing automatic temperature control and ensuring your heating system is balanced, these valves help reduce energy waste, which can lead to lower heating bills compared to older, non-thermostatic valves.

What colours are available?

The LavaTherm Radiator Valve Twin Pack is available in several modern finishes including Brushed Brass, Black, Anthracite, and Chrome, to match various radiator styles.

Troubleshooting

Radiator not heating up at all

Check if the TRV head is set to a low temperature or '0'. Ensure the central heating system is on and the boiler is functioning. Verify the lockshield valve is open.

Radiator is too hot, even when TRV is set low

The TRV valve pin might be stuck open. Gently try to free the pin by pushing it in and out a few times. If it persists, the TRV may need replacing.

Uneven heating between radiators

Adjust the lockshield valve on the radiators that are heating too much. Close it slightly to reduce flow to those radiators, allowing more hot water to reach others.

Valve is leaking

Ensure all compression fittings are securely tightened. If leaking from the valve body itself, the valve may be faulty and require replacement.

TRV head is difficult to turn

The TRV pin may be stiff. Gently try to move the pin up and down with your fingers or a tool. If it remains stuck, it might need replacement.

Pros and Cons

Pros

  • Provides automatic room temperature control for enhanced comfort.
  • Balances the heating system for even heat distribution across all radiators.
  • Potential for energy savings and reduced heating bills.
  • Universal 15 mm compatibility suits most UK heating systems.
  • Stylish design options to match home decor.

Cons

  • Installation requires basic plumbing skills or professional assistance.
  • TRV can be less effective in drafty rooms without proper sealing.

Setup, Compatibility & Care

Setup:

  1. Ensure the central heating system is turned off and drained to a level below the radiators being worked on.
  2. Unscrew the old TRV and lockshield valve from the radiator.
  3. Attach the new LavaTherm TRV to the radiator's inlet pipe, ensuring the arrow on the valve body points in the direction of water flow.
  4. Attach the new Lockshield valve to the radiator's outlet pipe.
  5. Connect the pipework using appropriate fittings, tightening securely but avoiding over-tightening.
  6. Refill and bleed the central heating system.
  7. Set the desired temperature on the TRV head.

Compatibility:

  • Designed for standard 15 mm UK central-heating pipework.
  • Compatible with most common radiator types and boiler systems.
  • Check your existing pipework size before purchase if unsure.

Care:

  • To clean, wipe the valves with a soft, damp cloth. Avoid abrasive cleaners.
  • Periodically check for leaks and ensure the TRV head can turn freely. If it feels stiff, it may need gentle exercise (turn it through its full range of motion a few times).
