How Colorado’s Move to Ultra-Low NOx Standards Impacts Plumbing and Homeowners

Colorado has taken a major step toward improving air quality by adopting ultra-low nitrogen oxide (NOx) standards for gas appliances, including water heaters and boilers. While this change is great news for the environment, it has also introduced new considerations for homeowners and plumbing systems across the Denver metro area.
What Are Ultra-Low NOx Standards?
NOx gases are harmful emissions produced by fuel-burning appliances. In an effort to reduce smog and protect air quality along the Front Range, Colorado now requires many new gas appliances to meet ultra-low NOx emission standards. These appliances release significantly fewer pollutants than older models.
For homeowners in Denver, Greenwood Village, Cherry Hills Village, and surrounding areas, this means that when replacing a water heater or upgrading plumbing equipment, compliance is no longer optional—it’s required.
How This Affects Water Heaters and Plumbing Systems
Ultra-low NOx water heaters are designed differently than traditional models. They often include advanced burner technology and specific venting requirements. As a result, installations must be done correctly by a licensed and knowledgeable plumbing company.

Benefits for Homeowners
- While these systems may look more complex, the benefits are real:
