What is MagnaClean filter

A MagnaClean filter is a piece of plumbing equipment that is attached to the returning water pipe of a Hydronic Heating System that captures harmful iron oxide particles. Capturing these particles means that they are not passing though your boiler, the pump and any hydronic radiator panels. Sludge in your system make the boiler and pump have to work harder and this will shorten its working life.

How a MagnaClean Improves Running Costs

Hydronic Radiator Thermal Image

Iron oxide sludge builds up within your hydronic heating panels will reduce the amount of heat energy output from your panels, which in turn means the boiler will have to run longer to raise the room temperature. The longer it runs the more energy it consume’s and the higher your running costs.

The thermal image of the radiator panel is showing an inefficient panel. The blue area means it’s cold, and should be hot. The only reason it is cold is because it will be full of sludge, the image should show an even orange over the whole panel.

A MagnaClean reduces your runnings costs by ensuring it’s running at full efficiency with no sludge.

A MagnaClean filter would have captured this, and during an annual service the sludge will have been removed. While a MagnaClean filter will capture most sludge it won’t capture it all as some sludge will still collect in the panels, just far more slowly. This is why a system requires a power flush around every 5 years. If you are unsure whether your system is full of sludge we can do a temperature test during a hydronic heating service and let you know.


A MagnaClean can be installed on a new job or an existing system. If it is to be installed on an existing system that is a few years old a power flush may be necessary. A power flush is when we force water through your system which stirs up any sludge and then captures that sludge with our equipment which is made up of a huge MagnaClean.
