Single Wall Stove Pipe Vs Double Wall Stove Pipe

When venting smoke from a wood-burning stove, two types of pipes are used: single wall and double wall. Each has distinct construction requirements and offers distinct advantages.

Single wall pipe is made from a single layer of cold-rolled steel with smoother welded seams and easy installation. It effectively radiates heat and warms rooms quickly.


Single wall stove pipe is an excellent option for homeowners with smaller houses who want to save money on installation costs. You can get this type of pipe in various sizes and with various connections for connecting it to your chimney. Plus, its crimped end helps keep creosote out of both the pipe and stove itself.

Double wall stove pipe is a more expensive option, but it provides superior insulation and resistance to creosote buildup. Not only does this help prevent fires, but it also keeps your flue gases warm to reduce condensation.

Double wall stove pipes consist of an outer layer made from black steel material and an inner wall composed of stainless steel. These pieces of metal can be welded or rolled together for a seamless, insulated pipe.

Double wall stove pipe installation is simpler than single wall due to the smaller clearance required from combustibles compared to 18″. Instead of needing 18″, only 6 inches must be cleared from walls and ceilings for double wall installation.

This makes it the ideal solution for people who need to maximize their space. Furthermore, those living in small homes or apartments and looking to stretch their budget should consider this type of arrangement as well.

Another advantage of double wall stove pipe is that it’s compatible with almost any type of stove, including EPA-certified pellet and corn stoves. However, if you’re uncertain which stove type to purchase, consult a professional for safety assurance.

Single wall pipe is a cost-effective option for those on a tight budget, though it may be difficult to find one compatible with your stove model. You may need to invest in an adapter in order to use it with your stove.

Single wall stove pipes offer several advantages over double wall alternatives, the primary being cost effectiveness. Installation is effortless and it quickly distributes heat from your wood stove so rooms are warmed more quickly. Unfortunately, over time they may deteriorate and need replacement – however this type of pipe is easy enough for most DIYers to handle!


Single wall stove pipe is a popular option for those wishing to vent their wood-burning or pellet stoves. It is lighter and simpler to install than double wall pipe, however it does not provide the same insulation.

However, single wall pipes do radiate heat well and heat rooms quickly. Some come with telescopic versions so you can adjust the height to one that works best for you and your home.

Single wall pipes also offer the benefit of cost efficiency, being cheaper than double wall stove pipes. This makes them a popular option for those on a budget and those who have limited workspace to work with.

In addition to its cost effectiveness, single wall pipe is less likely to degrade over time than double wall pipes – an advantage for homeowners planning on staying in their homes for an extended period.

There are exceptions to this rule, however. Always consult your local building code before installing any pipes in your home.

It is essential to install single wall pipes in areas with a minimum clearance of 18 inches from walls or ceilings for safety purposes. They should not run directly through any combustible walls or chimney chase as this could pose a fire hazard.

When using a single wall pipe for cooking, make sure it’s properly insulated to prevent fires from occurring. The most suitable material for this purpose would be stainless steel or copper.

Insulated stove pipe may even feature a fume-free finish, so you won’t have to worry about the smell of smoke in your home when using the stove. This makes installation and maintaining your appliance much simpler since there’s no risk of burning yourself or someone else down the chimney with it.

Furthermore, the ideal insulated single wall pipe should be welded for extra security and health benefits when using wood or pellet stoves with small flue collars. Welded connections help guarantee a tight fit and ensure safety during operation of your stove, especially when dealing with potentially hazardous fuels like coal.


Selecting the type of stove pipe for your wood-burning fireplace or stove is an integral part of safety and installation. There are two primary varieties: single wall and double wall. Each has its own advantages, drawbacks, and requirements for installation – so take time to understand these distinctions so you can decide which option is best suited to your home and heating requirements.

Single wall stove pipe is constructed from a single layer of cold rolled stainless steel with an almost invisible seam. It’s easy to install and ideal for use in chimney thimbles or ceiling transition boxes.

However, single wall stove pipe radiates a great deal of heat, so it should only be used in areas with at least 18 inches clearance from walls or ceiling for maximum fire protection. Furthermore, ensure the pipe has a fume-free finish to reduce smoke inhalation during combustion.

Double wall stove pipe is a safer option than single wall because it is insulated from the outside, protecting it from overheating and burning when in use. Furthermore, this reduces creosote buildup and moisture buildup inside of chimney flues.

It is essential to note that double and triple wall insulated pipe must meet UL standards. Essentially, this means they can safely operate at an internal temperature of 1,000deg Fahrenheit or higher, as well as withstand temperatures of 1,700deg for a limited time period.

Another advantage of double wall pipe is that it requires less clearance from combustible walls and ceilings – usually 6 inches or less.

Though this might seem like a minor detail, it can make a big difference when it comes to the safety of your system. Make sure that your home has an effective security system that won’t put anyone at risk in your home.

Single wall pipes are more cost-effective than their double wall counterparts, but they lack the same safety benefits and can corrode rapidly if left uncovered. Furthermore, due to the material and construction, a single wall pipe may be more vulnerable to corrosion and damage over time due to exposure.


Selecting the type of stove pipe for your wood-burning stove is one of the most critical decisions you will make. Not only does it ensure safety and performance in your chimney system, but it can also have an impact on how attractively your home looks.

Stove pipes come in two main varieties, single wall and double wall. Both serve different purposes and are tailored for specific uses, yet both can be installed safely and efficiently.

Single wall stove pipes are perfect for installations requiring clearance of at least 18 inches from combustible ceilings or walls. They come in various sizes, such as 6″, 7″, 8″ and 10.

Another advantage of single wall pipe is its increased heat output. This can be beneficial when creating more warmth in your house or using a heat reclaimer to extract as much warmth from your stove as possible.

Single wall stove pipe is more cost-effective than double wall, making it a great option for homeowners on a budget.

If you are not confident installing stove pipe yourself, hiring a professional may be your best bet. These experts can guarantee a secure installation and ensure your new system complies with local building codes.

Additionally, they can suggest the ideal brands of stove pipe and chimney systems to meet your requirements. Doing so not only saves you money in the long run but also guarantees your system performs optimally.

Double wall stove pipe is more durable and versatile than single wall pipe, allowing it to be used for extended periods. Furthermore, this insulation keeps flue gases warm while preventing creosote buildup in your chimney system.

Double wall pipe can be more costly than single wall pipe, so you should carefully weigh your options against your budget. This decision is especially pertinent if you plan to use a stove with high fuel load and need to install it in an awkward space or have an extensive chimney height.
