Simply dip the test strip into the system water and it will instantly change colour. By comparing the test strip to the colour chart label on the bottle, installers can assess whether the system water includes the correct concentration of inhibitor. A fully protected system will have inhibitor levels of 100ppm or above – and will pass the test. However, if the test fails and a result of less than 100ppm is received, the system should be re-dosed.
How to clean a heating system?
Systems should be cleaned when commissioning a new system or installing a new boiler within an existing system. The purpose of cleaning and flushing is to remove mineral oil, harmful flux residues and installation debris which can cause corrosion. Cleaning existing systems removes magnetite (black iron oxide), haematite (red iron oxide) and limescale improving the circulation and reducing fuel wastage
