How will upgrading your water heater help clear our air?

Residential water heaters are a significant source of nitrogen oxides (NOx), which contribute to formation of ozone and fine particulates (PM2.5), amplifying Utah’s summertime and wintertime air quality issues. You can reduce your NOx emissions by 75% by replacing your old water heater with a water heater that meets ultra-low NOx (ULN) standards.


The ShowUCAIR Water Heater Rebate program will offer eligible homeowners a rebate to cover 50% of the total purchase price, including sales tax and installation of a new ULN water heater, up to $500.

How to Apply

To apply for a rebate, a homeowner must submit the simple application along with the supporting documentation listed below. Once the application has been received, UCAIR staff will verify the information on the application to determine eligibility. After an application has been approved, a rebate check will be mailed to the applicant at the mailing address provided.

All water heaters purchased in Utah stores after July 1, 2018 should be compliant with ULN standards and eligible for a rebate through this program. However, it is the applicant’s responsibility to ensure that the water heater they purchase meets ULN standards, especially if this purchase takes place over the internet.

All rebates will be provided directly to homeowner/applicants, not vendors or installers. Rebates will be made available on a first come, first serve basis and limited to one per household. Only complete applications will be approved for a rebate. If we need additional information, we will contact you at the email address listed on your application. It is the applicant’s responsibility to provide the additional information in a timely manner.

Take advantage of this opportunity to offset the cost of a new, ultra-low NOx water heater and help clean the air we breathe.
