Proposed Bay Area Water Heater Rules Could Increase Compliance Costs
USA: A proposed rule by the Bay Area Air Quality Management District could tighten nitrogen oxide (NOx) limits for natural gas fired water heaters and boilers, potentially pushing many replacement products towards zero NOx technology. The proposal could increase costs, limit product availability and add paperwork for distributors, contractors and customers. Exemptions are available for situations such as limited electrical capacity, space constraints, emergency replacements and certain affordable housing projects, but some require advance approval and documentation. Industry representatives are calling for practical compliance timelines, clearer exemptions and consideration of product availability and installation challenges before the rule is implemented.
