Powerflushing & Chemical Flushing

Power Flushing

Powerflushing is a process that involves cleaning the inside of a heating system to remove any build-up of sludge, rust or other debris that may have accumulated over time. This is done by using a specialised machine that pumps water and chemicals through the system at high pressure, dislodging and removing any unwanted materials.

Chemical Flushing

Chemical flushing is a gentler method of flushing a system and uses highly concentrated chemicals along with industrial grade filters (also known as MagnaCleanse filters) to clean the system and uses the existing pump to circulate the chemicals around. We also use a special tool known as an agitator to help the sludge and magnetite loosen from the radiators so it can make its way to the filters.

Power Flushing & Chemical Flushing

Powerflushing and Chemical flushing is a crucial process that can help to restore the efficiency of your heating
system, improve its lifespan, and reduce energy bills.

Here are some of the benefits of Powerflushing your system:

Improved heating performance: With a cleaner system your boiler can heat up your radiators at a quicker pace.

Reduced energy bills: When your heating system is clogged with sludge and debris, it has to work harder to heat your home, which can lead to increased energy bills.

Longer lifespan for your heating system: A build-up of sludge and debris can cause damage to your heating system and more crucially your boiler leading to more frequent repairs.

Quieter operation: If your radiators or circulating pump are making unusual noises, it could be due to a build-up of debris causing restrictions or blockages.

To Summarise:

In summary, Powerflushing is an essential process for any heating system that can help improve water quality and intern give you a better performing boiler and system.

A Powerflush uses a high-pressure machine to push chemicals and water through your system, giving a deep clean.
A Chemical Flush is gentler, using your existing pump along with concentrated chemicals and MagnaCleanse filtration. We often use an agitator to break up stubborn sludge.

This depends on the size of your heating system. Smaller systems may take a few hours, while larger ones can take most of the day. If you contact us, we can give you an estimated timescale based on your property.
