Coffee with Caleffi™: Siegenthaler Examines Water Quality in Hydronic Systems

Share With:

Many installers simply fill their newly installed hydronic systems with water that’s available on site. Sometimes they’re “lucky” to have water with relatively low dissolved solids, stable pH and low turbidity. Other times they may not be so lucky. Although problems may not appear right away, the life of their new system could be significantly shortened by a combination of minerals in the water, solder flux residue, cutting oils in piping and glycol-based antifreeze solutions.
