Product Information

Full details

The LavaTherm Radiator Valve Twin Pack is designed for homeowners looking to upgrade their central heating system for improved comfort and energy efficiency. This pack provides a complete solution with both a Thermostatic Radiator Valve (TRV) and a Lockshield valve, essential for balanced and automatically regulated heating. While it offers significant benefits for consistent room temperatures and potential cost savings, users should ensure their existing pipework is standard 15 mm UK size for compatibility.

FAQs

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

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

Will this twin pack fit my radiator?

The LavaTherm twin pack is designed for standard 15 mm UK central heating pipework and is compatible with most radiators and boilers. It's ideal for upgrading older manual valves.

How do I set the temperature on the TRV?

The TRV head typically has a dial with numbers (e.g., 1-5). Higher numbers correspond to higher temperature settings. Refer to the product manual for specific setting recommendations.

Can I install this myself?

While installation is relatively straightforward for those with basic plumbing knowledge and tools, it involves working with your central heating system. If you are unsure, it is recommended to hire a qualified plumber.

How many twin packs do I need?

You will need one twin pack (one TRV and one Lockshield) for each radiator you wish to upgrade or control individually.

What does the Anthracite finish look like?

Anthracite is a dark, modern grey finish that offers a sophisticated look, often complementing contemporary radiators and interior designs.

Can I replace just the TRV or just the Lockshield?

While you can purchase TRVs and Lockshields separately, this pack provides a matched set for a complete and balanced installation on a single radiator.

Troubleshooting

Radiator not heating up at all

Check if the TRV head has been pushed in too far, preventing the pin from releasing. Try gently pulling the pin out with pliers. Ensure the central heating system is on and water is flowing.

Radiator is too hot or too cold

For TRVs: Adjust the setting on the TRV head. For Lockshields: Adjust the balancing valve. Consult a professional if unsure about balancing procedures.

Leaks from valve connections

Turn off the system, drain the radiator, and re-tighten the valve connections. If leaks persist, the seals may need replacement.

TRV head is loose or damaged

Gently try to tighten the retaining nut. If the head is significantly damaged, it may need replacement.

Pros and Cons

Pros

  • Improves room temperature consistency with automatic control.
  • Helps reduce energy waste and potentially lower heating bills.
  • Ensures even heating across all radiators in a system.
  • Simple installation for standard 15 mm UK pipework.
  • Modern finishes available to match home decor.
  • Provides a complete TRV and Lockshield set in one pack.

Cons

  • Only compatible with standard 15 mm UK pipework.

  • TRV settings might need occasional fine-tuning for optimal comfort.
  • Benefits are most noticeable in systems that were previously unbalanced or poorly controlled.

Setup, Compatibility & Care

Compatibility: This 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 valves are 15 mm and that your pipework configuration allows for the installation of both a TRV and a Lockshield valve.

Installation:

  1. Isolate Water: Turn off your central heating system and drain down the radiator you are working on to prevent water spillage.
  2. Remove Old Valves: Unscrew the existing radiator valves.
  3. Install Lockshield: Fit the Lockshield valve onto the radiator's return pipe connection. Ensure it is hand-tightened and then given a quarter-turn with a spanner.
  4. Install TRV: Fit the TRV onto the radiator's inlet pipe connection. Ensure it is correctly oriented (usually indicated by an arrow for flow direction) and tightened appropriately.
  5. Refill & Bleed: Refill the central heating system and bleed any air from the radiator.
  6. Test: Turn on the heating system and check for leaks, and ensure the TRV and Lockshield are functioning correctly.

Care: Wipe the valves with a soft, damp cloth periodically to keep them clean. Avoid using abrasive cleaners or solvents. Ensure the TRV head is not obstructed by curtains or furniture, as this can affect its temperature-sensing capabilities.
