The main advantage of B-vent over single wall pipe is its ability to provide better draft. B-vent is designed with insulation that helps maintain a higher temperature of the exhaust gases, which enhances the draft performance. This improved draft is essential for efficient venting of flue gases from appliances, as it allows for better airflow and prevents issues related to the buildup of gases within the system.

In contrast, single wall pipe lacks this insulating design, which can lead to cooler flue gases and potential draft issues. This diminished draft can result in inefficient performance of gas appliances, increased risk of backdraft, and may require more frequent maintenance due to the resulting condensation and soot buildup. While other factors such as cost, maintenance, and aesthetics are important in choosing venting solutions, the superior draft capability of B-vent is particularly critical for ensuring safe and effective operation of gas appliances.
