In early 2025, a major safety announcement affected thousands of homes across the United States and Canada—a Triangle Tube recall was issued for several popular gas boiler models due to a potentially dangerous defect.
If you own one of these units or are responsible for a home with hydronic heating, it’s important to understand what the Triangle Tube boiler recall involves, what dangers it addresses, and what you should do next.
The recall specifically applies to certain Prestige Solo, Prestige Excellence, and Aerco Esteem condensing gas boilers manufactured from December 2011 through April 2019. These units were sold with serial numbers beginning with prefixes including AE, PT, PA, PTE, and PEA.
Together, approximately 60,000 boilers sold in the U.S. and another 7,500 in Canada are affected by the recall.
Why the Triangle Tube Recall Happened
The Triangle Tube recall in 2025 was initiated because the affected boiler models were found to have a potential carbon monoxide (CO) hazard. Carbon monoxide is a colorless, odorless gas that can be deadly at high levels because it interferes with the body’s ability to absorb oxygen.
In this case, delayed ignition or internal component issues in these boilers can allow carbon monoxide to escape into the living space rather than being vented safely outside.
Officials have documented multiple reports of CO leaks associated with these recalled boilers. Triangle Tube and the U.S. Consumer Product Safety Commission (CPSC) also recorded at least two deaths linked to carbon monoxide exposure from these units—one in 2015 and another in 2016—along with numerous incidents of elevated CO levels.
Because of the serious safety risk, the recall is not just a routine notice but an urgent safety action. If you have one of the recalled Triangle Tube boilers, you should act promptly to protect your family and household.
How to Know If Your Boiler Is Part of the Recall
Identifying whether your boiler is included in the triangle tube recall involves checking the model and serial number on your unit. The boiler’s serial number typically appears on a rating label located on the boiler’s front panel or inside the access door. Models included in the recall have prefixes like AE, PT, PA, PTE, and PEA, and they were manufactured between late 2011 and early 2019.
If you’re unsure how to read the label or where to find it, most recall notices provide images and examples to help homeowners match their unit. Triangle Tube’s recall website offers a portal and instructions for identifying impacted equipment.
What Triangle Tube Is Offering
Triangle Tube has arranged for free inspections and corrective repairs for boilers covered by the recall. If your boiler is affected, you can contact Triangle Tube directly—through their website, dedicated recall phone line, or email—to register for a no-charge inspection. If a defect is confirmed, they will provide the necessary repair work at no cost to the homeowner.
In many cases, the recall remedy includes updating or replacing the ignition components to eliminate the conditions that could lead to carbon monoxide escape. The recall coverage may also include free carbon monoxide detectors if your home does not already have them.
While waiting for your inspection or repair appointment, it’s strongly advised to ensure that you have functioning carbon monoxide detectors installed on every level of your home, and especially outside sleeping areas. This safety step helps protect your household even if you are still using a recalled boiler before it’s serviced.
What You Should Do Next
If you own—or suspect you might own—a Triangle Tube boiler that could be part of the 2025 recall, here’s what you should do:
- Check your boiler’s model and serial number against the recall list on Triangle Tube’s official recall site.
- Contact the recall hotline or visit the Triangle Tube portal to register your unit for inspection.
- Install or test carbon monoxide detectors throughout your home if they are not already in place.
- Ask about recall repairs—they are offered free of charge to homeowners with affected boilers.
Taking these steps can help reduce health risks and ensure your home remains safe and comfortable.
