		Power Flushing
		We are experts in Power-Flushing old systems. All systems need power-flushing before a new boiler is fitted, and need power-flushing regularly to maintain the good regulation of the system. Power-flusing will soon be a regulation to be followed for all official installers. Call us for a free estimate on 01473 828806 or email us at contact@gallagherboilers.co.uk
		Power Flushing, Jet Flushing & Hard Flushing
		These are all expressions used (in the heating trade over many years) to denote the process by which heating systems are forcibly cleansed using water at high velocity, but low pressure, so that no physical damage is caused to the system. The process can be made even more effective with the addition of powerful cleansing and mobilising agents. The objective is to restore systems with circulation and boiler noise problems (caused by sludge and corrosion deposits) to optimum operation. Power flushing removes these deposits and the problems that they cause. Power flushing is also an excellent way to pre-commission clean new heating systems, to remove excess flux, swarf and other debris, and the grease and oil used to prevent rusting of components before use.
		All of the following problems can be easily solved by powerflushing your system
			Boiler Failure Cause: Assuming no other faults exist, the insulating effect of accumulated deposits of sludge and scale can restrict the transfer of heat to such an extent that the boiler overheats and fractures.
			Fuel Wastage Cause: In untreated heating systems, corrosion debris accumulates in the boiler and, in hard water areas lime scale will form. The insulating effect of these deposits reduces heat transfer to the circulating water. 3mm of lime scale deposit on the heat exchanger will add 18% to your fuel bill. It is in the current British Standards requirements that prior to boiler change, the system must be cleaned, powerflushing is the best way to achieve a proper well done job.
			Pump Seizure & Failure Cause: Black Oxide sludge, being abrasive and magnetisable, increases shaft and bearing wear which is the most common cause of sticking pumps and pump failures.
			Cold Radiators Cause: Sediment of iron oxide sludge accumulating at the bottom of radiators restricts the flow pattern.
			Frequent Venting, Cold Spots Near Top of the Radiator Cause: Hydrogen, sometimes mistaken for air, is a by-product of electrolytic corrosion. It is flammable and can be identified easily.
			Sludge and Scale Cause: Black Oxide sludge forms continuously in all unprotected central heating systems as a result of corrosion. It will also harden into scale on the hottest surfaces of a system. (i.e. the boiler heat exchanger causing it to make knocking and kettling noises). This prohibits efficient heat transfer. Boiler Manufactures will not guarantee your new boiler installation if the system is not chemically cleaned. The British Standards and the Benchmark demand that the system should be thoroughly cleaned.
		It is prudent to power flush a heating system immediately before fitting a new boiler to an existing system to prevent possible future problems. Many systems are found to contain corrosion and sludge, even if no flow problems have yet shown themselves. Existing debris is often mobilised by alterations to the system/piping and the increased efficiency of the new boiler, and may then accumulate in the boiler heat exchanger, causing noisy operation, reduced efficiency and, in extreme circumstances, failure of the boiler. The high efficiency and compactness of modern boilers, developed to minimise fuel costs and pollution, means that they are more susceptible to problems caused by debris in the system water.
