High Chloride Water and Hydronic Heating
The building's water supply has high chlorides (1000ppm+) and high free chlorine (Cl2), as well. To reduce corrosion of metal components (stainless steel heat exchanger, thermisters, etc., in the closed loop hydronic system, it has been suggested to flush the system using TSP, blow it out with compressed air, and fill the system with bottled water.
Question: What kind of water am I looking for? Spring, distilled, ionized, de-ionized, filtered, etc.
Also, glycol may or may not be used... pros and cons for this, too.
If anyone has any feedback on this, it would be greatly appreciated. The more info, the better. Elaborate as you see fit. Thanks.
