Powerflush pack – Rad Clean is a faster, cheaper, more effective method of cleaning domestic heating systems. This method evolved using experience gained from large scale industrial heating and cooling systems and trials with heating engineers. Rad clean should be used when the heat exchanger has been replaced or does not need cleaning. If the heat exchanger also needs cleaning, please see Full System Flush.

For dirty systems, we have found that a combination of the two products below is a quick, efficient, and economical method of Powerflushing the radiators and pipework. By cleaning all radiators in one loop, some of our customers are reporting powerflushing in around two hours.

Powerflush pack – Rad Clean involves using two separate products; Sludge & Flux Remover and Siltfree for the radiators and pipework.

How it works:

  1. Silt Free is a flocculent blend that is typically used to shift deposits of silt, mud and sand etc from open drains. Silt Free gives the particles buoyancy in water and by putting a small electrical charge on each particle, causes them to repel each other. Material treated with Silt Free will not form a solid mass again. This enables the silt and sludge content of heating systems to be more easily removed with Powerflushing. The product is suitable for superheated high-pressure systems.
  2. Sludge and Flux Remover cleans and neutralises flux residues, debris, oils and grease from new and old systems, as well as flocculating magnetite sludges and particulate residues, to facilitate their easy removal with a Powerflush machine. Sludge and Flux Remover is suitable for use with all components. It will not harm aluminium and requires no neutralisation. The product can remove light rust and helps to descale and soften water. Note: These products do not require neutralisation.
