Is there value in powered anodes for hydronic systems?

MatthewPK

I have a radiant floor hydronic heating system using a modern modcon boiler. The tubing is not air-barrier so oxygen can get introduced.

Is there any value in working in a powered anode? The expense of the equipment is minor but if it potentially improves system health or longevity it might be worth doing.

I've seen other commentary that sacrificial rods are not good for this use because their particles will create more problems.

A Vacume Degasification unit will help with this issue. I have a video from the last ISH in Frankfurt that has a clear demo of a a small residential unit that i can share with you.

Please Privat message me and i can send this to you directly.

I don't really have any system problems that I'm aware of, mostly wondering about powered anodes

I am very versed on behalf of this subject

I was the Chairman on the Hydronics Standard Committee that created the " None chemical "portion of the ANSI H 1001.1 Standard.

This "None Chemical " portion has many aspects that are very similar to the German VDI 2035 Standard.

Not having a O2 barrier in a system will not have negative result immediately ! It can take years and can very distructive.

Since there are many factor to consider when dealing with the lack of a O2 barrier i can have a one on one conversation with you regarding the Proper usage of " unpowered" Anodes in conjunction with Deionized H2o in modern hydronic heating systems (if you wish).

Happy 2024 Memorial Day !
