Natural gas boiler tune-up rebate
A tune-up can reduce the natural gas consumed by your boiler by up to 20 percent and increase its output. Puget Sound Energy's (PSE's) natural gas customers can receive rebates for 100 percent of the tune-up cost, up to $600. Additional repairs that increase the efficiency of your boiler, including boiler replacement, may also qualify for PSE energy efficiency grant funding.
A tune-up can restore a natural gas boiler to its normal efficient operating condition by detecting and correcting excess air losses, smoking, unburned fuel losses, sooting, fireside fouling and high flue gas temperatures. The boiler tune-up start with measuring the oxygen concentration, flue gas temperature, and emissions. Then the air/fuel ratio is adjusted to the optimum point of combustion efficiency.
Eligibility
This rebate is available to non-residential customers who purchase natural gas from PSE for hot water or steam boilers over 300,000 Btu/hr that are equipped with power burners.
Eligibility guidelines
- Perform pre-tune-up combustion efficiency tests across the full range of load using an electronic flue gas analyzer and print out the results.
- Tune the natural gas boiler
- Perform post-tune-up combustion efficiency tests across the full range of the load and print out the results.
- Send the completed rebate application, analyzer test printouts, and copies of your contractor's invoice with separate charges for labor, parts and taxes.
There is no limit on the number of tune-up rebates that may be awarded to a customer for different boilers, but each boiler is limited to one tune-up rebate. A separate rebate application must be submitted for each boiler tuned.
A natural gas boiler tune-up may identify other energy efficiency improvements that may qualify for a PSE energy efficiency grant. These include:
- Boiler replacement
- Boiler/burner controls
- Replacing motors with high efficiency motors
How to participate
Step 1. Verify that your boiler is supplied with natural gas by PSE, is at least 300,000 Btu/hr, and is equipped with a power burner.
- You are responsible to ensure the technician provides adequate documentation.
Step 3. Perform the tune-up
- A qualified boiler technician performs the tune-up and completes the rebate application.
- If in-house personnel will perform the tune-up, contact a PSE Energy Advisor at 1-800-562-1482 for requirements.
Step 4. Submit rebate application and documentation to PSE for processing. Include:
- Completed natural gas boiler tune-up application - one form for each boiler
- Pre-tune-up combustion efficiency tests
- Post-tune-up combustion efficiency tests
- Copies of contractor's invoice
