A permit lands in this list only when its description says water heater or tankless. A swap filed under a vaguer description is not in the number, so a company can do more of this work than its count shows.
194 listed companies have at least one water heater permit, and the 50 with the most are shown. The first has 444 water heater permits. The first five together hold 988 of the 2,446. Listed companies hold 2,174 of these 2,446 permits. The other 272 name no contractor or a company we don't list. Permits do not capture all work.
