Double Wall Interior Stove Pipe

Experience the pinnacle of stovepipe design with DVL's double-wall, air-insulated structure. This innovative design dramatically reduces combustible clearances from 18 inches to a mere 6 inches - the industry's closest wall clearance. By maintaining high flue gas temperatures, DVL ensures a robust and consistent draft, enhancing stove performance.

The stainless steel inner wall ensures rapid heat-up, prolonged heat retention, and significantly reduces creosote formation, aligning its lifespan with that of the chimney. Our adjustable lengths eliminate the need for cutting or crimping, simplifying installation.

Q. What is a double wall stove pipe?

A. A double wall stove pipe is a type of chimney pipe used to vent wood stoves, fireplaces, or other solid fuel burning appliances. It consists of two layers of metal pipe with insulation in between to keep the outside of the pipe cooler.

Q. What are the benefits of using a double wall stove pipe?

A. The benefits of using a double wall stove pipe include improved safety, increased efficiency, and reduced clearance requirements. The insulated pipe reduces the risk of chimney fires by keeping the outside of the pipe cooler. It also improves the efficiency of the stove by keeping the exhaust gases hotter, which helps to create a stronger draft. Finally, double wall stove pipes typically have reduced clearance requirements, which means they can be installed closer to combustible materials than single wall pipes.

Q. Is double wall stove pipe safe?

A. Yes, double wall stove pipe is designed to be safe and durable when installed and used properly. However, it is important to follow the manufacturer's instructions and to have the chimney inspected and cleaned regularly to ensure proper ventilation and to prevent creosote buildup.

Q. Can double wall stove pipe be used with any type of stove?

A. Double wall stove pipe can be used with most types of stoves that burn solid fuel, including wood stoves, pellet stoves, and gas stoves. However, it is important to follow the manufacturer's instructions and to choose the appropriate type of pipe for the specific stove or appliance being used.

Q. How often does double wall stove pipe need to be cleaned?

A. Double wall stove pipe should be cleaned regularly to prevent creosote buildup and to ensure proper ventilation. The frequency of cleaning will depend on the type of fuel being burned, the amount of use, and other factors. It is recommended to have the chimney inspected and cleaned at least once a year by a qualified professional.

Q. What is the difference between double wall stove pipe and single wall stove pipe?

A. The main difference between Duravent double wall stove pipe and single wall stove pipe is that double wall pipe has two layers of metal with insulation between them, while single wall pipe has only one layer of metal. Double wall pipe is more efficient and safer because it prevents heat loss and keeps the outer wall cooler, reducing the risk of chimney fires.

Q. Can double wall stove pipe be used for outdoor applications?

A. Double wall stove pipe is designed for indoor use only and should not be used for outdoor applications. If an outdoor application is needed, a different type of chimney system specifically designed for outdoor use should be used.

Q. Can double wall stove pipe be painted?

A. Yes, double wall stove pipe can be painted with high-temperature paint. However, it is important to use paint specifically designed for use on stove pipe and to follow the manufacturer's instructions carefully.

Q. What is the lifespan of double wall stove pipe?

A. The lifespan of double wall stove pipe depends on the specific installation and use, as well as the quality of the materials used. Consult with a qualified professional to determine the appropriate lifespan for your installation.

Q. How do I clean double wall stove pipe?

A. Double wall stove pipe should be cleaned regularly to remove any buildup of creosote and other debris. A qualified professional can perform a thorough cleaning, or the homeowner can use a chimney brush to clean the inside of the pipe.
