Main Changes
Prior to this new standard, water heaters and storage tanks were typically certified to UL 174 (electrical type) and ANSI Z21.10.1 or ANSI Z21.10.3 (gas types). With the new standard, water heaters & water storage tanks to be used in a solar thermal system (including solar pool systems) will need to be certified to BSR/ICC 903/SRCC 500 in addition to either the UL or ANSI standards.
