Stopcor ICCP for Heating Systems
« on: February 23, 2021, 01:57:55 pm »
Seems "sound in practice" they do cite some actual factual information on the site however after looking at ships implementations of these devices comparing their product and some of the claims such as limescale prevention through Brownian motion, I'm sceptical to say the least.

Seems like common sense if it was this simple, everyone would already be doing it. Applying a galvanic cell's electrical charge to a pipe. (Is the wall even a good enough ground)

Thoughts?

Sacrificial anodes (cathodic protection) are a thing and have been for a very long time. Not sure how easy it would be to implement inside a domestic heating system though...

That it basically what I'm getting at, I understand how the "zincs" on boats function. They have a common electrolyte however isn't that a requirement? I've not seen a single diagram without a common electrolyte for this type of protection? (sacrificial anodes)

(Edit: Sacrificial Anodes are used in water heaters and are quite common place and they reside inside the water tank this works on the same principle as the zincs welded / fastened onto a boat hull)

This device also doesn't claim to function how zincs work, the output is a voltage / current from the cell you create when adding the electrolyte (tap water) to the device, which is then applied to the pipe through a conductor which is suppose to impress a current and make the differential as close to equal between the two dissimilar metals (making the anode more noble and turning it cathodic) which mitigates the galvanic corrosion process? Or am I missing something here?

But when you look at the diagrams for commercial ICCP units they all have a common electrolyte with the ICCP anode (usually a very noble metal) within the same electrolyte as the normally cathodic metal and the more anodic metal which you're trying to protect.

They also have monitoring systems actively giving feedback so it provides the correct amount but I'm overlooking that part for now for simplicity.

This is a good source I've found on it so far.
