1. About the NaviCirc
NaviCirc is a circulation device for standard domestic hot water lines
without a recirculation system. It allows domestic hot water lines
and domestic cold water lines to connect to the NaviCirc and pre-
heat hot water lines by circulating hot and cold water through the
NaviCirc. This prevents hot water loss and heating time loss.
To prevent too much hot water from owing into the cold water line,
the NaviCirc includes a feature that automatically blocks circulation
when reaching a temperature of approximately 95°F (35°C).
