On November 3, 2025, Triangle Tube abruptly shut down all operations, leaving homeowners with Triangle Tube boilers suddenly without warranty coverage or reliable access to replacement parts.
For Eastern Ontario homeowners with a Triangle Tube boiler installed, this news raises understandable concerns.
While ATEL Air is not a supplier of Triangle Tube, we know many residents rely on these systems, and we are here to help with professional boiler repair, installation & replacement services.

About the Triangle Tube Closure
Triangle Tube’s closure followed a Health Canada recall involving their Prestige Solo, Prestige Excellence, and Aerco Esteem gas boilers.
These units were found to pose a carbon monoxide risk due to delayed ignition and potential component failures. Approximately 7,500 boilers in Canada and 60,000 in the U.S. were affected.
If your system falls within the recalled models, we strongly recommend scheduling a safety inspection to ensure it’s operating properly and does not pose a risk to your household.
Beyond the recall, the company cited rising tariffs and operational challenges as contributing factors. As of November 3, 2025:
- All equipment and accessory orders are cancelled
- No new orders are being processed
- Production of systems and parts has ceased
Triangle Tube has stated that its Product Safety Recall Program is still active, but the company’s closure severely limits long-term support.
How the Shutdown Impacts Triangle Tube Owners
The closure affects homeowners in several significant ways:
1. All Manufacturer Warranties are Void
Regardless of installation date, Triangle Tube warranties no longer apply. Any repairs or failures are now fully out-of-pocket for the homeowner.
2. Replacement Parts Will Become Scarce
Some suppliers may still have remaining inventory, but once those parts are used, no restocking is possible. Essential components (igniters, heat exchangers, sensors, valves) will be harder to find and more expensive.
3. Repairs May Become Impossible
As parts disappear, even straightforward service issues may become impossible. This increases the likelihood that complete boiler replacement becomes the only option.
4. Proactive Inspection is Strongly Recommended
If you own a Triangle Tube boiler, now is the time to:
- Have the system inspected by a licensed HVAC technician
- Replace any aging or failing components while parts still exist
- Discuss future replacement planning
This situation also highlights why manufacturer stability, parts availability, and warranty strength are so important when choosing a boiler brand for your home.
