Dangers of "Cellular Core" Piping in HVAC Systems

INDIANAPOLIS - Oct. 30, 2024 - PRLog -- In recent years, concerns surrounding "cellular core" piping in HVAC systems have intensified, prompting experts to raise alarms about its safety. Commonly used in exhaust systems for high-efficiency furnaces, boilers, and water heaters, "cellular core" piping is made of PVC or ABS and features a hollow core, making it lighter and cheaper than solid core alternatives. However, these cost savings come at a significant risk.

"Cellular core" piping is not designed to withstand the higher temperatures produced by exhaust gases from modern heating systems. Prolonged exposure can cause the inner structure of the pipe to warp or crack, leading to holes that allow toxic gases like carbon monoxide to escape into living spaces. This poses a serious health risk, as carbon monoxide is colorless and odorless, making it particularly dangerous.

Many cities and states are taking action. For instance, Loveland, Colorado, has prohibited the use of cellular core piping for exhaust systems due to safety concerns. Other states, including California, New York, and Massachusetts, are also implementing regulations that limit or ban the use of this type of piping in HVAC systems.

Homeowners are advised to take immediate action if they suspect the use of "cellular core" piping in their homes. Regular inspections of exhaust pipes near heating appliances are crucial. If any pipes are labeled "cellular core," homeowners should consult a qualified HVAC contractor for evaluation and potential replacement with solid core alternatives, which are better equipped to handle exhaust temperatures.

Additionally, installing carbon monoxide detectors in mechanical rooms or near affected piping can provide early warning of potential leaks.

As safety regulations evolve, homeowners must stay informed about local building codes regarding piping materials. Regular inspections and adherence to updated regulations can significantly enhance home safety. For more information, homeowners are encouraged to consult with a professional HVAC contractor to assess any risks associated with their current installations.
