New Regulations on the Horizon: DOE and SCAQMD Requirements for Commercial Hot Water Systems
"The best preparation for tomorrow is doing your best today." - H. Jackson Brown, Jr.
As a leading provider of commercial hot water solutions for multi-family properties and commercial buildings, Bateman Water Heating Engineering, Inc. (BWHEI) is dedicated to informing our customers and clients about upcoming regulatory changes that may impact their central hot water systems.
Two significant regulations are on the horizon: the Department of Energy (DOE) Commercial Water Heater Efficiency Requirements, effective in 2026, and the proposed changes to the South Coast Air Quality Management District (SCAQMD) Rule 1146.2.
Let's delve into how these regulations will affect building owners with existing central commercial hot water equipment.
DOE Commercial Water Heater Efficiency Requirements (2026):
The DOE is implementing new energy efficiency standards for commercial water heaters manufactured and installed in 2026 and beyond. These standards aim to reduce energy consumption and greenhouse gas emissions associated with water heating.
Impact on Existing Buildings: While these new standards primarily affect manufacturers, building owners (Multi-Family buildings, Condominium HOAs, and Commercial buildings with Central Hot Water Systems) may indirectly experience the impact when it comes time to replace or upgrade their existing equipment. The new, more efficient models may have different specifications or installation requirements, which could necessitate modifications to existing plumbing or electrical systems.
SCAQMD Proposed Rule 1146.2 Changes:
The SCAQMD is proposing amendments to Rule 1146.2, which regulates nitrogen oxide (NOx) emissions from large water heaters, small boilers, and process heaters. These changes aim to reduce NOx emissions further, contributing to air pollution and smog formation.
Impact on Existing Buildings: The proposed changes could significantly impact existing buildings (Multi-Family buildings, Condominium HOAs, and Commercial buildings with Central Hot Water Systems) with older hot water equipment that may not meet the new, more stringent NOx emission limits. Building owners may be required to upgrade or replace their equipment to comply with the updated rule.
THESE DIFFERENCES MAKE A STRONGER IMPACT IN REDUCING THE EFFECTS OF CLIMATE CHANGE AND AIR POLLUTION WHEN IT COMES TO CENTRAL HOT WATER EQUIPMENT IN MULTI-FAMILY AND COMMERCIAL BUILDINGS.
Key Differences Between the South Coast Air Quality Management District Rule 1146.2, SCAQMD & Department of Energy DOE Regulations on Commercial Water Heating Equipment:
Regulation | Focus | Impact on Existing Buildings |
DOE Commercial Water Heater Efficiency | Energy Efficiency | There will be an indirect impact when replacing or upgrading equipment. New models may require modifications to existing systems (effective 2026). |
SCAQMD Rule 1146.2 | NOx Emissions | Direct impact on older equipment that may not meet stricter emission limits, potentially requiring replacement and or upgrades (estimated to become effective in 2026). |
PREPARING FOR THE CHANGES WITH EXISTING CENTRAL HOT WATER EQUIPMENT IN GREATER LOS ANGELES
While the exact details and implementation timelines for the SCAQMD regulations are still evolving, building owners can take proactive steps to prepare:
Stay Informed: Keep abreast of the latest updates from the DOE and SCAQMD regarding these regulations.
Assess Your Equipment: Evaluate your existing hot water equipment's age, condition, and efficiency. Consult with BWHEI experts to determine if your system will likely meet the new standards.
Explore Options: Research available upgrades or replacements that comply with the new regulations. Consider factors such as energy efficiency, emissions performance, and cost-effectiveness.
Budget for Potential Costs: Start planning for potential expenses associated with equipment upgrades or replacements. Explore available incentives or financing options to help offset the costs.
