How to Choose the Correct Vent Type for Your Stove
It's time to cover the different vent types for your stove. Some have fuel type or termination restrictions, and all have their own strengths and weaknesses. Proper ventilation is essential to operating safely, so let's discuss the differences between each vent type to set you up for success.
- Wood Chimney: These vent systems are designed only for wood-burning stoves. Wood chimney venting and direct venting are popular choices, though wood chimney venting is less efficient. Wood chimney pipe can be single-walled or double-walled, and generally terminates vertically.
- B-Vent: Also known as "natural vent," B-Vent components are double-walled and rely on indoor air for combustion. They use negative pressure to draw air into the stove and cannot be terminated horizontally. B-Vent options are generally cost-effective and easy to install but less efficient than direct venting or vent-free options. This type of venting is becoming less common but is still a favorite of builders and contractors.
- Pellet Vent: Pellet venting is designed especially for pellet-burning stoves. Pellet vent components are double-walled and typically feature a galvanized steel outer wall. Pellet vent systems are completely airtight, making routine checks for air leaks essential. Many pellet vent systems use positive pressure to vent exhaust and terminate horizontally or vertically.
- Direct Vent: Direct vent systems use outside air for combustion and vent the byproducts directly outdoors. These systems terminate horizontally or vertically. Direct vent components are only compatible with direct vent stoves. Direct venting is easy to install and highly efficient compared to wood-burning systems, making it very popular.
- Vent-Free: Vent-free stoves require no venting at all. They are generally easier to install and offer more flexibility in where they can be installed. Electric stoves are popular and efficient options that require no venting.
- Unlisted Vent: Unlisted stoves are models that the manufacturer has not tested. As such, closely following your stove's installation instructions is crucial to ensure proper operation. They require greater clearances from combustibles than other vent systems and are far less common.
