FAQs
What is a TRV and why do I need one?
A Thermostatic Radiator Valve (TRV) is a radiator control that allows you to set a desired temperature for individual rooms. It automatically adjusts the hot water flow into the radiator to maintain that temperature, preventing overheating and saving energy.
What does the 'DO' on the lockshield valve mean?
'DO' stands for Drain-Off. This feature allows you to isolate and drain water from a single radiator without needing to drain your entire central heating system, making maintenance tasks much easier.
How do I set the correct temperature on the TRV?
The TRV head has numbered settings, typically from 1 to 5. These numbers correspond to approximate room temperatures. '1' is usually around 10-12°C (frost protection), and '5' is around 25-28°C. Higher numbers mean higher temperatures. You can experiment to find the setting that achieves your desired comfort level for each room.
Can I install this myself?
Installation requires basic plumbing knowledge and the ability to turn off your heating system and handle water. If you are not comfortable with these tasks, it is recommended to hire a qualified plumber.
Is this twin pack suitable for all radiators?
This twin pack is designed for 15/10mm pipe sizes and standard domestic radiator systems. The 'angle' configuration is specific to radiators where the pipework enters the radiator at an angle.
How often should I use the drain-off function?
The drain-off function is primarily for maintenance. You might use it if you need to bleed air from the radiator, replace the radiator, or perform other servicing. It's not typically needed for regular operation.
What is the warranty period for this product?
Please refer to the manufacturer's warranty information provided with the product packaging or on the Home Range website for specific warranty details.
Troubleshooting
Radiator not heating up at all
Ensure the TRV is not set to the '0' (frost protection) setting. Check that the lockshield valve is fully open. Verify that the pin on the TRV is not stuck; if it is, try to free it gently with pliers (ensure the system is off and cool).
Radiator is always too hot, even on low setting
Check that the TRV head is correctly fitted and that the pin can move freely. Ensure the lockshield valve is not fully open if you require lower heat output. Consider if the TRV setting corresponds correctly to the desired room temperature.
Leaking from the valve connection
Turn off the system, drain the radiator, and re-tighten the compression nuts. If the leak persists, you may need to re-tape the threads or replace the internal seal.
Drain-off valve is dripping
Ensure the valve is fully closed. If it continues to drip, the internal washer may need replacing. Turn off the system, drain the radiator, and replace the washer.

- Ensure your radiator has the appropriate fittings for an angle TRV.
Care:
- Clean the exterior with a soft, damp cloth. Avoid abrasive cleaners.
- Periodically check for leaks around the connections.
- Ensure the TRV head can move freely; if stiff, gently try to rotate it (when the system is cool).
- The drain-off valve may require occasional checking to ensure it is free from debris.
