Powerflush is a cleansing process which aims to not only remove but eliminate deposits of sludge, rust and any other debris from your central heating system.
These toxins, if left, can seriously affect the efficiency of a heating system and in severe cases can damage the central heating all together.
Signs that you might need a Powerflush
Look for a number of signs before deciding to go ahead with the Powerflush process. These include cold areas on radiators, excessive noise from the boiler or the heating system pump, discoloured water when you bleed the radiators and the slow warming of the heating system. You might also notice the tap water getting cloudy, especially if there is a build-up of lime scale as well.
The Powerflush process
The generally aim of a Powerflush is to restore the full circulation of water around the central heating system, it can also eliminate noise from the boiler and the pump as well. This means that the entire central heating system has to be flushed in order to get the best results.
A qualified heating engineer will connect a powerful high flow/low pressure pumping unit to the central heating system; either to the circulation pump in the regular boiler systems or the pump head in combination boilers. To finish it off with the help of high strength cleansing chemicals will also flush out anything in the system.
The chemicals used during a Powerflush include a sludge crust breaker and remover to help get rid of rust and sludge, a descaler to break down lime scale and a corrosion inhibitor to stop further rusting from occurring. The crust breaker and remover are acid-based so that they help to combat any rust present and any other debris, such as sand particles, that might have settled in the radiators, pipes and boiler. At the end of the process there is no acid left in the central heating system’s water.
Cost and time needed for a Powerflush
Logical Heating & Plumbing Solutions power flushing engineer state that a full Powerflush will take around 6 hours to complete. This is an estimate though as some badly affected heating systems will require more time whilst others may be finished quicker.
The price of a full system Powerflush varies with location and the size of the heating system and can range from approximately £350 up to £1200+. Occasionally the descaler isn’t included in the original quoted price and needs to be paid for on top.
It is important that your central heating system is as efficient at all times and although a Powerflush can be an expensive process, it can also save a lot of money over time with regards to your heating bills but should be used in conjunction with a complete boiler service for best results.
The process is clean and safe when done by a professional and can quickly eliminate cold radiators and noisy boilers and pumps.
