    IAPMO R&T Announces New American National Standard for Solar Heating Systems

    Ontario, Calif. — IAPMO R&T, a leading developer of standards for the plumbing, mechanical and solar industries, is pleased to announce that the new standard IAPMO/ANSI S1001.1, Design and Installation of Solar Water Heating Systems, has been approved by the American National Standards Institute (ANSI) as an American National Standard.

    IAPMO’s S1001 Solar Standards Technical Subcommittee members met in a collaborative and open process to develop a solar water heating system standard that is completely transparent and reflects the technical realities of today’s solar heating marketplace.

    The purposes of this standard are to establish generally acceptable minimum quality criteria for the design and installation of residential and small commercial solar water heating systems; to serve as a guide for manufacturers, distributors, architects, engineers, contractors, code authorities, program administrators and end-users; to promote understanding regarding materials, manufacture and installation; to form a basis for fair competition; and to provide a basis for consistency and fitness for use of solar water heating systems.

    For 87 years The IAPMO Group has offered a comprehensive menu of services — product testing and certification, code and standard development, training and education — offering clients one-stop shopping for all of their solar, plumbing and mechanical needs.
