Magnetite or Sludge in Gas Central Heating

Magnetite Sludge in Central Heating Systems
With out a good inhibitor (or perhaps in some cases with!) a heating system with metallic radiators Is going to corrode inside. This corrosion is generally known as black sludge or magnetite sludge. This clogs circulating pumps, zone valves, radiator valves and heat exchangers. With central heating boilers which use iron heat exchangers, further corrosion usually takes place. Amazingly, It can bring an entire halt with a central heating system within months / years from the system being installed. This is a condition that is costing the general public and property owners millions of pounds to put right. Nevertheless, the top cure is prevention. Magnetic separators ( magnaclean filters , boiler guard , boiler buddy , tf1 etc ) have been recognized for quite some time as crucial inside food as well as healthcare products industries. They guarantee that products are marketed free from metal contaminants. Their bonus to wet central heating systems is undoubtedly apparent.

In new boilers, vulnerable heat exchangers and internal parts are generally be subject to rust deposits from degrading iron radiators. These deposits are commonly referred to magnetite-sludge. The magnetic filter is completely are able of inhibiting magnetite sludge from coming into the boiler. The strong magnets will attract deposits as they pass in the movement of water – adhering to the inside walls of the Magnetic filter capture chamber. As a result of it’s design, the flow of water will never be impeded. Routinely, the filter should be isolated and washed out. Turn off the connections and lift the body out. The inside of the product may then merely be washed in running water.

There isn’t a hard and fast rule on how frequently the unit should be removed and cleaned. Every 1-2 years is normally enough on most systems. However, if the unit was installed in order to beat a known magnetite-sludge trouble then clearly it need to be washed soon after installation, and possibly every 1 to 2 years from then on.


We believe it is more essential than ever before that long-term central heating boiler defense is given by something permanent. Only including a chemical inhibitor to the system is just not good enough. Systems can leak and get rid of water through pressure release valves – this means any added inhibitor is lost. That makes the radiators prone to corrosion, and thus makes the boiler prone to corrosive deposits. Some modern central heating boilers tend to be easily blocked with magnetite. We have witnessed at first hand how boilers have been left defenceless against corrosion deposits and failed within their guarantee periods due to the fact the chemical inhibitor was lost via a water leak. A magnetic filter safeguards any central heating boiler from this type of scenario. That insurance policies are relatively inexpensive against the costs of system failure but no insurances will insure you regarding sludge in ones central heating system and would normally charge you for a powerflushing when sludge is discovered to be resulting in probelms with your central heating. A new magnet separator needs to be a standard fit to both old systems and new.
