    IAPMO will begin the Call for Comments on these documents on Oct. 7, when all suggested code amendments/additions/deletions published in the ROP will be available for public review. The deadline for submission of comments is Jan. 13, 2023, at 5 p.m. PST.

    The USHGC and USPSHTC are model codes developed by IAPMO to govern the installation and inspection of solar energy, hydronics and geothermal energy systems, as well as swimming pool, spa, and hot tub systems, respectively, as a means of promoting the public’s health, safety, and welfare. The 2024 edition of each code is being developed through a process accredited by the American National Standards Institute (ANSI).

    IAPMO urges its members and other interested parties to get involved in the development process to ensure effectiveness in preserving the public health, safety, and welfare. Manufacturers, potential users of the standard, installers and maintainers, labor representatives, design professionals, enforcing authorities, and consumers all benefit from a cooperative effort in developing codes and standards.
