Regulatory Environment

Water heating equipment is regulated by a number of government bodies–especially the Department of Energy (DOE)–industry organizations, codes and standards, as noted in the chart that follows. Additionally, boilers are regulated by a separate set of standards and codes, discussed in the Boiler Module of the Industrial Advisor. Issues addressed by these entities and rules primarily concern efficiency and safety.
