Required Documentation:
Boiler Sequencing
- Documents presenting the new control sequence.
- Boiler specifications. • Nominal unit ratings (MBH) for all boilers involved in the project.
Modulating Boiler Control
- It is recommended to collect boiler loading data documenting year-round operation and typical part loading throughout the year for university and hospital boilers.
- Incentive is based on boiler input capacity.
- Available for retrofit, boiler replacement, or as part of new construction.
- Process boiler must run year-round. HVAC boilers will run only during the heating season.
- University and hospital boilers are considered process boilers even if they provide space heating.
- Boilers primarily used for domestic hot water or pool or spa use are not eligible.
- Existing boilers must be on/off with no modulation.
- Redundant boilers do not qualify.
Linkageless Boiler Controls
- Boiler specifications.
- It is recommended to collect boiler loading data documenting year-round operation and typical part loading throughout the year for university and hospital boilers.
Oxygen Trim Control
- Boiler input capacity verification (e.g., nameplate, specs).
- It is recommended to collect boiler loading data documenting year-round operation and typical part loading throughout the year for university and hospital boilers. Also, to prove year-round operation.
Boiler Sequencing
- Applicability: Eligible for heating systems equipped with at least two boilers that are currently isolated and operate in parallel piping systems.
- Qualifying Efficiency Requirement: Enabled sequence controls.
- Exclusions:
- Redundant boilers.
- Other requirements:
- Boilers must be capable of being sequenced and staged, both enabled and disabled.
- Must ensure the hydronic flow is stopped within fifteen minutes of a boiler’s deactivation.
- Enable and disable boilers in a manner that optimizes their operation, adhering to the manufacturer’s recommendations.
Modulating Boiler Control
- Applicability: Eligible for retrofit, boiler replacement, and new construction projects.
- Qualifying Efficiency Requirement: Boilers must have a minimum turndown ratio of 5:1.
- Exclusions:
- Redundant boilers or boilers with low annual runtime hours.
- Boilers primarily used for domestic hot water or pool or spa.
- Other requirements:
- Process boilers must operate year-round, and HVAC boilers are utilized during the only heating season.
- University and hospital boilers, even those providing space heating, are considered process boilers.
- Existing boilers must currently operate on/off with no modulation.
Linkageless Boiler Controls
- Applicability: Eligible for existing boiler retrofit, new boilers, and new construction.
- Qualifying Efficiency Requirement: The replacement of existing linkage controls with linkageless controls
- Exclusions:
- Redundant boilers.
- Boilers primarily used for domestic hot water or pool or spa.
- New construction on HVAC boilers.
- Other requirements:
- Process boilers must operate year-round, and HVAC boilers are utilized during only the heating season (are limited to weather sensitive measures).
- University and hospital boilers, even those providing space heating, are considered process boilers.
Oxygen Trim Control
- Applicability: Eligible for retrofit, equipment replacement, and new construction projects.
- Baseline Efficiency: No O2 trim control.
- Exclusions:
- Redundant boilers.
- Oxygen controls required by EPA guidelines.
- Boilers primarily used for domestic hot water or pool or spa.
- Other requirements:
- Process boilers must operate year-round, and HVAC boilers are utilized only during the heating season.
- University and hospital boilers, even those providing space heating, are considered process boilers.
- Existing boilers must currently operate on/off with no modulation.
