Why Hydronic System Protection Isn’t Complete Without a Permanent Magnet…

Work on closed loop hydronic heating and cooling systems?

Does your install or service include equipment protection?

If so, does it include a permanent magnet?

If not; it should, and here’s why…

As soon as a new hydronic system is installed, the clock to counteracting corrosion begins.

Corrosion is a natural process that occurs in every system - residential or commercial, heating or cooling, old or new.

All new components are exposed to oxygen and other contaminants during the manufacturing, transportation, and storage process. Fluxes can build up on the inside of components such as pipework during installation, and air pockets are very common when filling a new system. Not to mention, most high-efficiency systems have a lot of dissimilar metals which can cause a galvanic reaction, leading to the onset of corrosion.

For existing systems, faulty air-vents, pinholes, plus all of the exposures during the install to begin with, accelerate the process of corrosion. Corrosion can never be completely stopped, but it can be slowed down through a simple process of testing, cleaning, and protecting of the system water. Cleaning and protecting doesn’t stop at the use of water treatment chemicals though. A magnetic filter on the return is also essential in ensuring long-term protection, to prolong component and system life, and enhance efficiency. It is also advised that an air and dirt separator be installed on the supply to aid continuous air removal from the system.

Why do I need magnets to protect the system?

The number one reason why is because the process of corrosion can never be stopped, and inhibitors contain a number of ingredients that provide protection using different mechanisms. Within these are film forming and absorption organic components. These are absorbed onto surfaces of metallic compounds including metal oxides to provide protection however, the more those metal oxides build up, the more the inhibitor is being absorbed. Without the use of a magnetic filter to capture the continuous build-up of metal oxides, inhibitors will eventually deplete, meaning the system will no longer be protected.
