How water behaves in hydronic systems - HPAC Magazi
Fresh water in North America typically has a pH between 6.0 and 8.5. The pH of fresh water in closed hydronic systems exhibits an interesting characteristic: independent of beginning pH, the water in properly designed, pressurized closed heating systems tends to stabilize to about eight pH. This level is acceptable for all common system metals.Get a Quote
