Why Choose a 2026 High-Efficiency Boiler?
The new state regulations aren’t just about the environment; they are an opportunity to drastically improve your home’s performance.
- Ultra-Low NOx Technology: New systems emit less than 14 ng/J of nitrogen oxide, significantly improving Colorado’s air quality and your home’s indoor environment.
- Space-Saving Combi Units: We install modern combination (combi) boilers that handle both your home’s heating and your domestic hot water from a single, wall-mounted unit.
- Whisper-Quiet Operation: High-efficiency boilers from brands like Carrier, Navien, and Lochinvar use advanced modulation to eliminate the banging and “kettling” of older systems.
- Lower Monthly Costs: Upgrading to a 95% AFUE (Annual Fuel Utilization Efficiency) unit can save the average Castle Rock household hundreds of dollars per year in gas costs.
2026 Rebates & Financial Incentives
Installing a boiler is a significant investment, but 2026 offers more ways to save than ever before:
- Federal Tax Credits (25C): Claim up to $600 for qualified high-efficiency boilers.
- Colorado HEAR Program: Low-to-moderate income households may qualify for point-of-sale discounts on high-efficiency equipment.
- Utility Rebates: We help you secure local rebates from Xcel Energy and CORE Electric that can total over $500 depending on the model’s efficiency rating.
