What is a Powerflush?

A Powerflush is a cleansing process which aims to remove deposits of sludge, rust and any other debris from your central heating system.

These contaminants, if left, can seriously affect the efficiency of a heating system and, in severe cases, a powerflush could be the only option available. Over time the water in your pipes, boiler and radiators deposits unwanted byproducts like rust. This rust (plus other dirt and debris) becomes an unpleasant, mud-like substance that professionals affectionately refer to as ‘sludge’.

Sludge in your heating system can cause to blockages and corrosion which will lead to both inefficiency and / or breakdown. In extreme cases it can be so damaging that a complete boiler replacement is needed.

Are you cleaning your system often enough?

The UK trade marketing manager for Sentinel, Daniel Cheung, claims, 'an up close and personal' approach is essential to maintaining a long-term, healthy, heating system. 

Filthy water circulating in your heating system is both common and damaging, as corrosion is the number one cause of boiler breakdowns. Corrosion can cause other expensive problems with your boiler including; repairs, part replacement, complete boiler failure, increased energy consumption, ineffective heating as a result of radiator cold spots, loss of boiler warranty and higher heating bills. 

Research from two leading boiler manufacturers found that in over 5000 homes 35% of heating systems under 5 years old and more than 50% of systems over 5 years old contain dirty circulating water. It is recommended for heating engineers to always consider dirty water when looking for solutions to boiler issues. For example, 'if the heat exchanger is clogged in a relatively new system' of it the pump shaft is broken it could be because of rust flakes in the water.

Considering a dirty system doesn't end with checking the quality of system water, but should also include a system cleanse. In order to do this effectively, the correct cleaning agents must be used and this is determined by the type of dirt present in the system. it is similar to how you wouldn't use shampoo to wash your clothes or washing up liquid to wash your toilet, different cleaning chemicals do different jobs.
