On June 1, 2023, Colorado signed House Bill 23-1161 into law, creating stricter water and energy efficiency standards for appliances and consumer products. This legislation aims to cut emissions, improve air quality, and lower long-term energy costs for homeowners.
For Colorado Springs and surrounding communities, the most significant impact will be the new furnace and water heater emissions standards beginning in 2026. Here’s what you need to know — and how to prepare.
Overview of Colorado’s New Appliance Efficiency Standards
HB 23-1161 applies to a wide range of products, from household fixtures to heating appliances. The law is designed to:
- Improve energy efficiency in Colorado homes
- Reduce nitrogen oxide (NOx) emissions
- Promote air quality and public health
- Save consumers money through reduced utility bills
These changes affect everyone, but the most notable updates are for furnaces, boilers, and water heaters.
What the New Furnace & Water Heater Emissions Standards Require
Stricter NOx Limits Starting in 2026
Beginning January 1, 2026, any new water heaters, boilers, or fan-type central furnaces sold in Colorado must meet tighter nitrogen oxide (NOx) emission limits.
Possible Tougher Standards by 2029
The Air Quality Control Commission must also evaluate whether to implement even stricter standards by 2029, so the rules may tighten further.
Why These Standards Matter
- NOx emissions contribute to smog and poor air quality.
- Stricter rules help improve health, especially for those with asthma or respiratory issues.
- Colorado homeowners should expect higher upfront prices on compliant systems due to new manufacturing requirements.

How These Changes Impact Colorado Homeowners
Higher Upfront Costs for New Units
As manufacturers adapt to meet emission standards, compliant furnaces and water heaters will likely cost more than current models.
Replacement Timelines and Compliance Deadlines
If your system is older and nearing replacement, acting before 2026 could save you money and avoid limited product availability.
Benefits for Air Quality and Long-Term Savings
Although the upfront investment may be higher, these systems improve efficiency, reduce utility bills, and support cleaner air in Colorado.
Preparing for Colorado’s Stricter Appliance Standards
Should You Replace Before 2026?
If your water heater, boiler, or furnace is approaching the end of its lifespan, replacing it before the new standards take effect could save you significant costs.
