What is the impact of moisture accumulation in the venting system?

Moisture accumulation in the venting system is significant because it may lead to corrosion and blockages. When water vapor condenses within the vent, it creates a hostile environment for the metal components of the venting system. Over time, this moisture can corrode metal surfaces, weakening the structural integrity of the vent. Additionally, sediment and particulates can accumulate in the presence of moisture, leading to blockages that impede the proper flow of combustion gases. This can affect the performance of combustion appliances, potentially resulting in hazardous situations such as backdrafting or reduced efficiency. Thus, understanding the consequences of moisture in venting systems is essential for maintaining safety and proper function in combustion appliances.
