Over a period of time there is likely to be a build up of solid deposits, such as chalk and limescale within the pipework and chambers of a central heating system. In addition, the presence of oxygen and chemicals in the water will cause a certain amount of corrosion of the metals which make up the system, producing ferrous oxides.
As these particles accumulate in the lowest parts of the system it causes a black or brown sludge to build up. This can cause blockages in the pipes or cold spots in radiators, worst of all, these these sludges can build up in the heat exchanger of your boiler, meaning that gas is not being used efficiently when burnt, causing you to use more fuel.
Powerflushing is now offered as a method of driving this sludge out of the system using water pumped under pressure through the system.
How is it done?
The Powerflush equipment is connected directly into your central heating system, usually by removing a radiator or the system circulation pump and connecting the Flushing pump in its place.
This way we can circulate clean water around the system under pressure with the intention of flushing out all the deposits and sludge build up. After adding a special cleaning compound, each radiator is powerflushed in turn followed by the boiler itself and the hot water cylinder coil, if your system has one. The equipment has several valves which allow us to either repeatedly reverse the pressure flow through the radiators. The process is only completed when we end up with clean water being circulated around the system.
Is Powerflush necessary?
We are convinced that using this method of cleaning the parts of a radiator system has always improved performance and economy and is vital in removing blockages. Pumping water under pressure through the pipework and radiators also helps to show any small leaks or defective valves in the system. Additionally Powerflushing is becoming a requirement for the guarantees on newly installed boilers to be valid.
