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.
Why Inhibitor Testing is Crucial
-
Inhibitor creates a protective layer on metal surfaces, preventing water from reacting with the pipes and causing rust and sludge. This sludge can block pipes and radiators, making the system work harder.
-
A clean system heats more effectively, leading to lower energy consumption and reduced heating bills. Limescale can also build up and block heat exchangers, making the boiler less efficient.
How Turbidity Testing Helps
A turbidity test measures the cloudiness of the water, indicating the level of suspended solids present in the system.
The test results help determine if treatment is needed to protect the boiler.
-
Clear water with documented inhibition may mean no action is needed.
-
Slightly blurred water may suggest adding chemical inhibitors, and potentially, a filter may be beneficial.
-
Completely black water indicates significant sludge and debris, necessitating a full flush with cleaner, and the addition of inhibitors is required.
-
By identifying water quality issues early, you can take action to prevent major problems and extend the life of your boiler significantly.

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.
