In January, the Federal Register provided an updated document highlighting energy conservation standards regarding boilers and minimum efficiencies. The new boiler energy conservation standards were set by the US Department of Energy to improve boiler efficiency, reduce energy consumption and limit emissions.
The information states that the DOE reviewed Commercial Packaged Boilers (CPB) standards and concluded that updating the existing 10 CPB equipment classes to 12 equipment classes is necessary. Updated guidelines include the following:
- Draft type is no longer a criterion for equipment class
- “Very large” commercial packaged boilers will have separate equipment classes
Eliminating draft type as a feature of equipment class consolidated the original 4 draft-specific equipment classes into 2 non-draft specific equipment classes. While separating “very large” commercial packaged boilers into their own equipment classes adds an additional 4 classes.
With these new equipment classes comes more stringent standards for 8 of the 12 equipment classes (including all classes except for the new “very large” CPB classes). The table clarifies the updated standards for all equipment listed, including prescribed minimum thermal efficiencies or combustion efficiencies as well as compliance dates.
So, what does this mean for you?
The benefits of energy conservation for boilers include reduced energy costs, lower gas emissions, improved energy efficiency and a longer lifespan for the boiler. These are great benefits, but updating and replacing equipment that complies with new standards may present a challenge.
Currently there is no deadline to replace boiler room equipment that is in use, but as this outdated equipment begins to fail, facilities will need to plan on how to replace their old equipment with something that meets the updated standards.
“This is going to require proper planning, well in advance of equipment failure. There are still extensive supply chain issues across the industry and new equipment is unavailable. Manufacturers are in the process of figuring out how to replace current equipment. Their older models no longer meet the energy efficiency act standards and they have to consider how to produce viable options for replacement. Customers will also have to consider the cost of updating venting to match the new boiler equipment. When installing a new condensing boiler, venting needs to be replaced with polypropylene or stainless-steel materials to meet modern codes.” – Jay Higgins, Sales Engineer, The Wilkinson Companies
