Powerflush A powerflush is the process of cleaning wet central heating systems in domestic and commercial properties.
Background Over time, all central heating systems suffer corrosion and the resulting buildup of contaminants. A powerflush pump is attached to the heating system and is used to pump water and chemicals around the system to remove contaminants and debris from the boiler, radiators and connecting pipework.
Contaminants and Debris Radiators in wet central heating systems are subject to corrosion caused by the presence of oxygen in the system water. The internal surfaces of the radiators rust and produce black iron oxide. Black iron oxide may be found suspended in the system water, or it may be lying as a sediment at the bottom of radiators or pipework. Black iron oxide is the most common contaminant in heating systems and it is commonly referred to as sludge.
Corrosion may also be caused by electrolysis, an electro mechanical reaction between dissimilar metals in close proximity within the system, such as between radiators (iron) and the radiator valves (brass alloy).
Some systems my have contaminated water. The wrong chemicals may have been used in the past or for some reason the acidity pH levels of the water my be incorrect. This can also cause corrosion in the system.
Other debris that a powerflush can remove from a heating system include builders sand, brick dust, sawdust, flux, solder, jointing compounds, insulation materials, etc.,
Damage caused by Debris and Contaminants The build up of black iron oxide in central heating systems, often called sludging-up, will result in the heating system becoming inefficient as the water is unable to circulate freely. Pipework can become blocked or partially blocked resulting in poor distribution of heat throughout the heating system.
Black iron oxide is abrasive and it is tacky and will stick to components in the system causing them to fail. Typical components that fail include circulation pump, diverter valves, pressure relief valves, expansion vessel, main heat exchangers and radiator valves.
Powerflush Process (Summary)
A powerflushing pump is attached to the heating system at the engineers choice. This could be on the tails of a removed radiator, the heating circulation pump, or the system pipework at the boiler. The engineer will determine the best location depending on the system design.
The powerflush pump will be used to established water flow throughout the system. Powerflush chemicals will be added via the powerflush pump and flushed throughout the system and the boiler may be activated to heat the system thus promoting chemical action.
Once chemicals have been flushed throughout the system, all radiators valves are shut off except for one radiator. This radiator is then cleaned. Once clean, it is shut off and the next radiator is opened and it is then cleaned. All radiators are thus individually powerflushed until the entire system is clean.
On completion of the powerflush a corrosion inhibitor is added to ensure that future corrosion is kept to a minimum. Notwithstanding, all systems will corrode to some degree, so regular water testing and treatment is recommended.
A detailed step by step guid to a powerflush may be found on powerflush pump manufacturer’s product user guides.
Powerflushing Accessories There are a variety of accessories to assist in a powerflush including equipment to vibrate on radiator panels, powerful magnets to trap contaminants, and electronic devices to test radiator temperatures. Water testing equipment is also available to test the water quality before, during and after a powerflush.
Powerflush People The success of each powerflush will be ultimately determined by the knowledge and experience of the person performing the powerflush. A number of independent specialist specialist providers of powerflush services are in existence. Any competent heating engineer with knowledge of vented, sealed, combi boiler, microbore, gravity hot water, single-pipe, single-feed cylinders and thermal store systems can undertake a powerflush.
Regulation In the UK powerflushing is not a regulated activity. It is not a requirement that the person performing a powerflush is Gas Safe registered.
