What is a Power Flush?

Power Flushing is the process by which heating systems are forcibly cleansed using water at high velocity, but low pressure. The process is made even more effective with the addition of powerful cleansing and mobilising chemical 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.

With circulation and efficiency re-established, you’ll reap the benefits of a warmer home right away, and also save money in the long term.

Signs that you might need power flushing

Many problems with your central heating can be related to sludge and debris issues. Regardless of the age of your heating system, if you spot any of the following issue, you may need power flushing:

  • Central heating is slow to warm up
  • Radiators are completely or partially cold
  • Radiators need frequent bleeding
  • The water in your radiators is discoloured and dirty
  • Radiators have pinhole perforations and leakages
  • Strange noises coming from your boiler
  • Pump failures and sludge deposits in pump casing

What are the benefits of power flushing?

Put simply, power flushing is investing in the future of your heating system:

A Power Flush can restore circulation and efficiency to your central heating system by removing undesirable products. It purges them from the system, replacing aggressive water with clean water, chemically treated with corrosion inhibitors to help prevent similar future problems.

  • The more sludge removed, the more effective your heating
  • Clean systems are much less likely to break down due to internal damage
  • Your whole system lasts much longer with proper inhibitor levels
  • You’ll spend less on breakdowns and repairs in the long-term

It is essential to Power Flush a heating system immediately before fitting a new boiler to an existing system in order to prevent possible future problems. It is also recommended you flush your heating system approximately every 5 years to maintain a healthy system. Heating systems may generate corrosion and sludge, even if no flow problems are apparent.

The Procedure

The Power Flush pump is connected into the heating system wherever is most practical. The powerful flow, combined with chemicals and the instantaneous flow reverse device, will dislodge and mobilise deposits and corrosion, which resist traditional system cleaning methods.

Once the corrosion and sludge deposits have been loosened and mobilised, fresh clean water is forced through a full bore dump valve to waste. During the process, radiators are individually flushed, without removing or disconnecting them from the system, by directing the full output of the pump through each radiator separately.

Our price for Power Flushing heating systems varies with the size of the property, boiler, radiator quantity and chemicals required. Prices start from about £240.00 + vat for a small property. However, an on-site survey can be completed before hand and a detailed quotation issued without obligation. Please get in touch for more details.
