Is your central heating system clogged with black sludge?

Are you experiencing poor heating or hot water performance, leaking or faulty radiators, sludge in your expansion tank, boiler noise (kettling) or trapped air in radiators? It sounds like your central heating system could do with power flushing. In addition, as a preventative measure, we sometimes recommend installing a magnetic filter to prevent loose particles of magnetite from entering your boiler in the future.

 Why power flush a heating system?

A power flush for a heating system is like a service for your heating system. When you service your boiler, you are only looking at the internal components of the gas or oil boiler. A power flush will clean the entire heating system, including the boilers heat exchangers.

Cleaning them, will remove any grime, sludge or lime build-up which reduces the efficiency of the entire heating system. Grime on radiators will cause cold spots and will reduce the amount of heat that a radiator are let out. Grime in a pump will cause additional wear and strain on the pump and will eventually stop it working. This will stop your entire heating system from operating. Grime build-up on your boilers heat exchangers will cause them to output less heat than when they were new.

The power flush chemicals will be forced around the entire heating system pipework and radiators and cylinder and this will get them shining internally. When we have finished with the cleaning chemical, we will input a system inhibitor to your heating system. This will prevent future build-up of grime, sludge or lime.

A Power flush is not required on all heating systems, though it can be beneficial for solving lots of heating system problems.

Please note that we will only power flush your heating system if we are replacing your boiler or installing a solar system at the same time.


Did you know?

  • Black magnetite sludge – rust from central heating equipment – is present in most central heating systems

  • It can affect the efficiency of your system, causing cold spots in radiators and requiring frequent bleeding
  • It clogs pumps and reduces the flow of water, making your system noisy and less efficient

How it works

Having carried out an assessment, we’ll drain your system and use a power flushing machine to force a cleaning agent through the system to remove the sludge.

This is a very effective solution for inefficient heating systems clogged up with sludge.
