This increases in frequency and intensity as deposits of sludge and scale build-up
in an unprotected boiler. The noise is caused by the deposits gathering in the water ways of the boiler in different thickness causing the water with in the exchanger to heat up at different rates causing the boiler to sound similar to a kettle.
The familiar cool, low central area of a radiator indicates a build-up of black sludge sediment
that restricts flow and reduces heat output.
When the top of a radiator is cold during operation, usually air or hydrogen is to blame. Hydrogen
gas builds-up as a by-product of electrolytic corrosion and is flammable (due caution is required).
Pump seizure and failure
The abrasive and magnetic properties of black oxide sludge increases shaft and bearing wear
in pumps causing them to stick or fail.
The inconvenience and cost of system breakdown can be easily avoided by taking three simple steps:
How to Maintain System Efficiency
Adding an inhibitor
Once the system has been thoroughly cleaned and flushed correctly, as outlined in Part L
of the Building Regulations and following best practice advice, the use of a chemical inhibitor and
Scale reducer will keep the system trouble free. Independent tests have recently proven if you protect a central heating system using Fernox Protector F1 500ml, after cleaning, gas savings of up to 15% can be achieved every time you heat your room.
Fitting a Magnetic Filter
This unique in-line filter is the only one on the market which uses specially designed magnetic assemblies to remove both magnetic and non-magnetic particles from system water and contain them safely within the filter. The Filters is not only compatible with chemical water treatment, it acts as a perfect dosing point for any chemical additives. Designed to last the life of the boiler, a magnetic filter be it Fernox TF1 or a MagnaClean system will give a belt and braces approach to protecting your boiler and central heating system.
