Inhibitor Testing Explained.
An inhibitor test for your boiler is important because a central heating inhibitor protects against the build-up of rust, sludge, and limescale, which can lead to blockages, decreased efficiency, and costly breakdowns. Regular testing ensures the correct inhibitor concentration, maintaining system efficiency, extending the boiler's life, preventing damage, and keeping the warranty valid.
Reasons for inhibitor testing
-
To prevent corrosion and scale:
An inhibitor is a chemical that protects internal components from rust and limescale buildup. Over time, its effectiveness diminishes, and the system's metal parts become vulnerable to damage.
-
To maintain system efficiency:
Without sufficient inhibitors, sludge can form and accumulate, blocking pipes and radiators, which prevents them from heating up efficiently and can make the system work harder, increasing energy bills.
-
To identify and rectify problems:
Testing can reveal if the inhibitor level is too low or if other issues exist, allowing a heating engineer to take corrective action before a major breakdown occurs.
-
To ensure boiler warranty validity:
Many manufacturers require regular servicing, including inhibitor level checks, to keep the boiler's warranty valid.
-
To ensure proper dosage: Testing confirms that the correct concentration of inhibitor is present, and the system is being protected long-term. It can help determine if a top-up or a full re-dose is needed.
When to Test
-
An annual test of inhibitor levels is recommended.
-
Regular updosing to ensure correct levels may be required.
-
If you've had a new boiler installed, a major repair or flushing off your system, inhibitor levels should be tested immediately to protect your system.
