MagnaCleanse Rapid Flush

Optional MagnaCleanse Rapid Flush upgrade

A new boiler works best when the existing heating system is clean and properly protected.

Where recommended, we can include a MagnaCleanse Rapid Flush as part of your boiler installation package. This helps remove sludge, magnetite and debris from the system before the new boiler is put into long-term use.

This can be particularly useful on older systems, properties with cold spots on radiators, or systems where the magnetic filter shows signs of heavy contamination.
