It is compatible with most standard UK residential central heating systems, provided the pipe diameter matches the valve specifications.
If you have basic plumbing experience, you can install this kit. However, if you are unsure, it is highly recommended to consult a professional plumber to avoid leaks or system damage.
A thermostatic valve allows you to set and maintain a specific room temperature, which can help save energy by preventing rooms from overheating.
Use a soft, dry, or slightly damp cloth. Avoid harsh chemicals or abrasive materials that could scratch or dull the gold plating.
Yes, the Derry Bold kit typically includes both the thermostatic head and the necessary installation components, such as the lockshield valve, for a complete setup.
Check if the internal pin is stuck due to inactivity; remove the TRV head and gently press the pin to ensure it moves freely.
Ensure the connection nuts are tightened correctly and check if sufficient PTFE tape was used on the thread during installation.
Ensure no debris is obstructing the head mechanism and that the valve is not overtightened against the pipework.
To install, ensure your heating system is fully drained before beginning the replacement process. The kit is designed for standard 15mm pipework common in most UK homes, though alternative variants are available for specific sizes. Always use PTFE tape on threads to ensure a watertight seal. For care and maintenance, wipe the gold finish gently with a soft, dry cloth. Avoid abrasive cleaners, bleach, or acidic solutions, as these can damage the protective finish and lead to premature wear or discoloration. Periodically check the valve connections during seasonal system testing to confirm there are no signs of minor leaks.
