This highly recommended environmentally friendly system treats hard water issues to address the water quality going into your Navien units, other water-related products and your water supply lines. A “must buy” in areas of hard water. Scale build-up from hard water is the biggest single reason for reduced performance.
PeakFlow C prevents scale by converting dissolved hardness minerals into powerless particles that will not attach themselves onto any of the components in the system. PeakFlow C, when sized correctly for the installation, will help to ensure the longevity of your system, and help eliminate hard water quality problems
