Both brands offer chimney pipe, chimney caps, stove pipe, and more to suit any installation need. DuraVent is an American company founded in 1948 and headquartered in Vacaville, CA. Their chimney systems are designed for use with gas, wood, or oil-burning appliances. DuraVent is known for their double-wall stainless steel pipes that provide an insulating air gap for efficiency and safety. DuraPlus chimney systems are manufactured by DuraVent's Canadian sister company, Security Chimneys International out of Montreal, Canada. DuraPlus is marketed as a more economical alternative to DuraVent with single-wall stainless steel construction. Also Read: Differences Between Selkirk And DuraVent Chimneys. Key Differences Between DuraVent And DuraPlus Chimney Systems Now let's look at how these two popular chimney brands compare across some key factors: Durability and Construction When it comes to sturdiness and longevity, DuraVent's double-wall design gives it the edge over DuraPlus's single-wall construction. The double-wall design sandwiches an insulating air layer between two stainless steel walls. This provides excellent protection against corrosion and reduces heat transfer for higher fuel efficiency. It also keeps the exterior chimney surface cooler for safety. DuraPlus uses a single layer of stainless steel which is still durable but more prone to exterior surface corrosion over time. The single wall also allows more heat transfer through the chimney. Both brands offer 25+ year warranties on their chimney systems so you can expect a long service life as long as the chimney is properly maintained. DuraVent's double-wall design likely means less maintenance and repairs down the road though. Durability and Construction Winner: DuraVent Ease of Installation Installing a chimney system correctly is critical for performance and safety. Both DuraVent and DuraPlus chimney parts assemble simply with twist-lock connections. DuraVent's double-wall piping is more rigid and self-supporting which makes partitions easier to stack. The connection points are also precision-machined for perfect alignment. DuraPlus single-wall parts are more lightweight and may require more brackets for support on taller chimney runs. The looser tolerances also allow more variance in joint alignment. When it comes to ease of installation, DuraVent once again has an advantage with their Sturdier pre-assembled chimney sections and precise fit designs. Ease of Installation Winner: DuraVent Design Flexibility Having flexible chimney options allows contractors and DIYers to tackle any installation scenario. Both brands offer adjustable length pipes and a variety of elbows for routing around obstacles. One area where DuraPlus pulls ahead is stove pipe options. DuraPlus offers both adjustable length stove pipes and snap-lock connections for easier installation and removal for cleaning. DuraVent's stove pipes have more limited size options and use screw-together connections. For chimney caps, DuraVent has a larger selection of decorative shrouds and styles to match your home's aesthetics and weather needs. DuraPlus has a smaller range of more basic chimney top options. Overall, both brands provide a diverse array of chimney components, but DuraPlus has an edge with more stove pipe flexibility while DuraVent leads in decorative chimney caps. Design Flexibility Winner: Tie Safety Safety should be your top priority when selecting any chimney product. DuraVent's double-wall design again provides added safety benefits over single-wall systems. The air gap insulation keeps the exterior surface cooler, preventing burns and reducing the risk of igniting nearby combustibles. It also minimizes creosote buildup by containing hot gases in the inner wall. Both manufacturers utilize stainless steel construction for excellent corrosion resistance and durability. DuraVent and DuraPlus also offer chimney liners, caps, and flashings made specifically for high-temperature appliances like wood stoves. Always make sure to have your chimney installed properly with required clearances. But DuraVent's superior insulating design reduces safety risks from excessive heat and creosote. Safety Winner: DuraVent Cost Comparison Since DuraVent systems utilize double-wall stainless steel pipes and precision-machined connections, they are the more expensive option when comparing directly with DuraPlus's single-wall components. However, the added material quality and performance you get with DuraVent can justify the cost over the system's lifetime. The enhanced safety and lower maintenance of DuraVent chimneys also helps offset the higher initial investment. If you're on a tighter budget though, DuraPlus provides a more affordable alternative without sacrificing quality construction. Just be prepared for somewhat lower efficiency and potentially quicker replacement compared to DuraVent. Here is a basic cost comparison if installing a basic 15-ft chimney system for a wood stove: DuraVent Chimney 15-ft kit - $600 DuraPlus Chimney 15-ft kit - $450 As you can see, DuraVent carries about a 25% premium over entry-level DuraPlus components. The cost difference may be less for larger custom chimney installations. Also Read: Comparison of DuraTech And DuraPlus Chimneys. Cost Winner: DuraPlus Appearance Beyond performance, you also want a chimney system that looks appropriate for your home's exterior. This is mainly determined by the chimney cap. DuraVent provides the most decorative cap options from contemporary metal styles to ornate copper shrouds. They offer a sleek modern look perfect for newer homes. DuraPlus has simpler cap designs including basic chimney pots. These tend to blend in better on traditional styled homes. Both brands provide chimney pipes in a brushed stainless finish that is neutral enough to match any home. DuraVent definitely leads in visual customization though. Appearance Winner: DuraVent Customer Support and Warranty DuraPlus Chimney Pipe A good chimney system should come with backing from the manufacturer long after installation. Both DuraVent and DuraPlus provide strong customer support resources and decent warranty coverage: DuraVent - Limited lifetime warranty on most products. Provide online FAQs and videos plus technical support line. DuraPlus - 25 year limited warranty on chimney parts. Have online documentation and email/phone technical support. While warranties are similar, DuraVent's customer support content including how-to videos sets them apart. Their wide availability and network of dealers also makes obtaining parts and service easier. Customer Support Winner: DuraVent DuraVent Or DuraPlus Chimneys: Which Is Best For You? Now that we've compared the key factors, which brand comes out on top? For superior safety, efficiency, durability, and looks - DuraVent is the best overall chimney system. The double-wall stainless steel construction provides excellent insulation and corrosion resistance. Precision-fit connections also allow for secure DIY or pro installation. However, if cost savings is your top priority - DuraPlus provides similar stainless steel quality and durability in a more affordable single-wall chimney system. Just be prepared to potentially have higher maintenance costs long-term. There are several additional factors to weigh based on your specific needs: Type of appliance (gas, wood, oil, pellet) you're venting Height/pitch of your roof Desired clearance from combustibles Aesthetic preferences Consult with your contractor on which chimney system best suits your installation requirements. And always make sure to follow local building codes and the manufacturer's instructions. Proper chimney setup is crucial for performance and safety, so don't cut corners. Investing in a quality system like DuraVent or DuraPlus will give you long-lasting, worry-free operation. Also Read: Comparison of DuraTech And DuraVent Chimneys.
