There are 3 different types of system flush that can be done when fitting a new boiler.

The first method is a ‘mains flush.’ This is where mains pressured cold water is put into the heating system and drained off .

The second method is a ‘Magnacleanse.’ This is where 2 large magnets and a bottle of cleaner are temporarily added to the heating system, the cleaner dislodges any dirt and debris, whilst the magnets collect it.

The third method is a ‘powerflush’ This is where a large pump is added to the heating system which pushes large volumes of water around the system dislodging dirt and debris.

On all of our boiler replacements, we use the Magnacleanse method, only when a heating system is very dirty would we recommend a powerflush.
