What is a MagnaCleanse flush and why might a Glasgow boiler need one?

MagnaCleanse is a method of cleaning magnetic debris from a central-heating system using specialist equipment and magnetic separation. It can help remove circulating sludge and contaminants before or during boiler replacement.

The aim is to avoid connecting a new boiler to dirty system water. Modern boilers have relatively narrow waterways and controls that can be affected by poor water quality. Cleaning should still be matched to the actual condition of the system; heavily restricted or damaged heating systems can require additional work beyond a standard clean.

Doherty includes a MagnaCleanse system flush and chemical treatment in its standard gas boiler packages. For older Glasgow heating systems, that inclusion matters because the condition of the existing radiators and pipework can be just as important as the new appliance.
