Combined Potable Water and Hydronic Heating Systems <br />Wirsbo AQUAPEX is used in combined potable water and hydronic heating <br />systems only where allowed by code. Depending on the heating control <br />strategy employed, these systems typically do not exceed 140°F. Should <br />the system water temperature exceed 140 IF, the installing contractor is <br />responsible for providing anti -scald devices to protect the inhabitants. In <br />addition, the installer must ensure, and is responsible for, providing weekly <br />off-season (summer) circulation through the heating portion of the system <br />to prevent water stagnation. <br />Refer to your local plumbing and heating code official as to whether these <br />combined systems are allowed in your area. If allowed within your area, <br />ensure a proper heat loss and design is completed that considers the loss <br />of heat energy between the two systems and the resulting impact on <br />either system's performance. <br />Hydronic Heating Systems <br />Wirsbo AQUAPEX can be used in closed-loop hydronic heating systems <br />operating at sustained temperatures up to 180°F, provided any issues <br />concerning oxygen diffusion are properly addressed. Corrodible or ferrous <br />components may not be used in a system designed with Wirsbo AQUAPEX <br />unless these components are isolated from the tubing. <br />Please see the Uponor Complete Design Assistance Manual (CDAM) for <br />information about using Wirsbo AQUAPEX in hydronic radiant heating <br />systems. Refer to the Uponor Snow and Ice Melting Design Manual for <br />information about using Wirsbo AQUAPEX for snow -melting applications. <br />Section 2 — Installation Options and Applications uponor <br />
