HEATING EQUIPMENT BOILERS
HOT WATER BOILERS Common Area Requirements: • Boiler rebates are only available for equipment used in space heating applications. Boilers used for only domestic hot water heating are not eligible for this rebate but may qualify for a custom incentive. • Must be a central plant type arrangement that serves multiple dwelling units in the multifamily building. • Space heating boilers also used for DHW may be eligible for indirect DHW rebates but are subject to requirements. • A boiler replacing a space heating and indirect DHW system will use the capacity of the existing space heating and DHW systems to estimate the split of rebates. • Boiler efficiency will be verified using the AHRI database (see ahridirectory.org). If the boiler is not listed in the AHRI database, provide a boiler specification sheet with boiler input and output ratings and either AFUE or thermal efficiency as appropriate for boiler size. • Steam boilers do not meet efficiency requirements and are not eligible for this rebate but may qualify for a custom incentive. Hot water boiler ≥90% thermal efficiency replacing a steam boiler is eligible. • ≥90% thermal efficiency boilers: • If the heating system configuration is such that the boiler needs to operate at a high hot water temperature, which prevents the flue gases from condensing, then the boiler is not eligible. • Hot water boilers ≥300 MBh:
• Boilers must be capable of capacity modulation. • Do not round AHRI capacity to a whole number.
