Extend your system’s life

Power flushing clears any sludge, cold spots, corrosion and black iron oxide deposits from your radiators, boiler and central heating pipework and controls.

The result is an instant boost to the life of both your boiler and central heating system.

Achieve peak performance

A power flush removes magnetite sludge and hydrogen build up throughout your system, meaning quicker heat-up times, reduced energy use, a quieter boiler and more.

On top of this, you can also expect an extended pump life and greater long-term health for your boiler and radiators, helping you save money in the future too.

How a power flush is done


A Norstrom or Kamco power flush machine and MagnaCleanse filter are connected to your boiler or central heating system’s pipe work.


The system is then flushed with specialist chemicals to give it the necessary deep clean it requires.


Upon completion of the power flushing process, the system contains fresh, clean water complete with inhibitor.

I had a new boiler install, which was relocated to my loft. I was recommended puzzle plumbers by a friend, who had said that they was a very honest and fair company. I was glad I did as the engineers came on time, worked cleanly, were friendly and their work was to a high standard.
