Boiler replacement in Denver
Smarter heat starts at the source
Not every boiler replacement means high tech; it means the right technology.
Advanced Hydronics
replaces aging
boilers
across Denver with systems engineered for comfort, efficiency, and longevity. We evaluate venting, gas supply, and existing emitters to match each home’s needs, whether that means a durable cast-iron boiler or a modulating condensing model. The result is quiet, steady comfort without surprises in neighborhoods like Cherry Hills Village, Capitol Hill, and Greenwood Village.
What an upgrade covers
A proper boiler replacement is more than a swap. We right-size the equipment, integrate outdoor reset control, and balance distribution to keep comfort consistent. Our team also evaluates domestic hot water so showers, laundry, and kitchen use stay reliable all day.
- Boilers selected and sized for actual system load, conventional or condensing as appropriate
- Outdoor reset and smart thermostats for steady temperature control
- Updated air elimination, low loss headers, and ECM circulators for smooth flow
- Clean, code compliant flue and condensate solutions for long term reliability


Why upgrades outperform repairs
High-efficiency boilers use advanced controls and heat exchangers to deliver more heat with less fuel. Modulating burners and outdoor reset adjust output to real-time conditions, keeping rooms steady without temperature swings. The result is quieter operation, lower emissions, and consistent comfort in spaces with large glass areas common in Denver remodels.
- Higher efficiency through modulation and condensing operation
- Quieter performance with smoother, continuous firing cycles
- Lower emissions and reduced energy costs throughout the season
- Organized mechanical rooms with labeled components for easy service
See why hydronics makes every upgrade worthwhile
High-efficiency boilers are only part of the story. Hydronic heat delivers quiet, even comfort and better air quality compared to forced air.

What to expect during your replacement
We start by assessing your current system, then coordinate installation with care for your home and schedule. Expect clear communication, organized work, and a finished system that performs exactly as promised.

Making the Most of a Modern Boiler Upgrade
When should I replace my boiler instead of repairing it?
Replacement makes sense when repair costs approach the value of the system or when efficiency and reliability decline. Aging boilers often show uneven heat, frequent lockouts, or rising energy bills. We evaluate condition, performance, and replacement cost before recommending the best option.
Can you upgrade my domestic hot water at the same time?
Absolutely. We often pair boiler replacements with indirect water heaters for faster recovery and reduced standby loss. This combination improves both comfort and mechanical-room efficiency.
Will upgrading improve efficiency right away?
Yes. Modern controls, outdoor reset, and modulating burners reduce cycling and fuel use from day one. Many homeowners also notice quieter operation and steadier comfort compared to older fixed-output models.
How long do modern boilers last?
Most high-efficiency boilers provide 20 years of service when maintained properly. Regular inspection and water-quality checks help preserve performance and prevent premature wear. Cast-iron boilers can provide up to 40 years of service.
Can a new boiler connect to my existing system?
Yes. We evaluate the system type, piping, emitters, and control strategy to ensure compatibility. When upgrades are needed, we adjust near-boiler piping, circulators, and venting so the new unit operates safely and efficiently.
