Replacing Your Boiler?

AERCO CFR: The only condensing boiler that allows you to re-use your existing chimney

If you're planning a boiler replacement and want to avoid costly, time-consuming flue upgrades, the AERCO CFR offers a smart, streamlined solution. It’s the first condensing boiler on the market that operates with a non-condensing flue—meaning you can reuse existing chimneys and venting systems with the ability to upgrade performance in the future when time and budget allows.

Why AERCO CFR?

• Use Current Vents
  • Installs into existing Category I flue systems
• Reduce Emissions & Save Money
  • Highest efficiency in its class (up to 87.6%)
  • Lowest NOx emissions (<20 ppm)
  • Can be upgraded in the field to condensing mode
• Easy to Install
  • Factory-assembled, compact, and fits through standard 36" doorways
• Backed by a 10-Year Warranty
  • Industry-leading coverage on key components

Whether you're looking to meet upcoming Local Law 97 emissions targets or simply seeking a more cost-effective way to modernize your building’s heating system, CFR is a future-ready solution. Its dual-mode capability lets it operate as a high-efficiency non-condensing unit today, with the option to switch to full condensing performance later..

Perfect for Urban Retrofits

With NYC’s carbon caps taking effect in 2025 and tightening by 2030 and beyond, the CFR provides immediate emission reductions and long-term flexibility. It’s especially well-suited to phased upgrade projects, where boilers are replaced one at a time or the flue is replaced later to meet ever increasing regulations. Quiet operation, compact design, and the ability to move through elevators and tight hallways make it ideal for occupied spaces.
