What about a mircoporus filter that the water in the closed loop would bypass through that would filter any salts or any mirco impurities from the stagnet water?
The industry standard is for reference only. Its the German Industry Standards(DIN). It does refer too plastic pipe.
In your opinion there is nothing good that could ever come from infusing the water in a hydronic heating system with Oxygen. At any level for any reason.
I'm just wondering when is too much of a good thing not a good thing? The industry standard for O2 diffusion rate is 0.1/liter/day at 40 C. When does dead water become an issue? Marginal quality water can lead to the delopment of scale, sediment deposits, or the creation of sludge in the heat...
A question has been raised in a Canadian pulp mill. Could the O2 level be too low causing the system to airlock and reduce heat transfer efficiency. We all know about diffusion but what is the limit?
