Triangle Tube, a long‑standing manufacturer of residential boilers, has ceased operations following a major nationwide boiler recall involving carbon monoxide (CO) safety risks. Homeowners, buyers, and sellers are now asking what this means for Triangle Tube boilers currently installed in homes.
Is Triangle Tube Out of Business?
Triangle Tube officially shut down operations in late 2025. Manufacturing, warranty processing, and factory technical support have ended. While some distributors may still have parts available, long‑term manufacturer support is no longer available.
Triangle Tube Boiler Recall Explained
In 2025, Triangle Tube issued a voluntary recall in cooperation with the U.S. Consumer Product Safety Commission (CPSC) and Health Canada. The recall affects certain Prestige Solo, Prestige Excellence, and Aerco Esteem gas boilers.
Why Were the Boilers Recalled?
The recalled boilers may experience delayed ignition or internal component failure, allowing carbon monoxide to escape into the home. Multiple carbon monoxide incidents and reported deaths were linked to affected units.
How the Shutdown Affects Homeowners
- Recall safety obligations remain in effect.
- Manufacturer warranties are no longer valid.
- Replacement parts may become increasingly difficult to source.
- Home inspections and real estate transactions may be impacted.
Should You Replace a Triangle Tube Boiler?
Replacement is often recommended for recalled units, older systems, or homes preparing for sale. A licensed HVAC professional can evaluate repair versus replacement options.
What Homeowners Should Do Now
- Verify model and serial number
- Confirm recall status
- Install and maintain carbon monoxide detectors
- Consult a licensed HVAC contractor
