A double wall stove pipe is meant for clearances of less than the 18 inches required for a single wall stove pipe. Like the single wall stove pipe, you would never run it directly through a combustible wall.
What kind of pipe do you use for a wood stove?
Single-Wall Stove Pipe The main benefit of single-wall pipe is that it is less costly than double-wall pipe. Single-Wall pipe effectively radiates heat back into your room and you can also install a heat reclaimer. A heat reclaimer forces air out from the chimney and can be installed 12"-24" above your wood stove.
Is it safe to use single wall stove pipe?
You need to look carefully at the wood stove manufacturer's requirements, but most wood stoves need a large draft to operate correctly and loss of heat through a single wall pipe causes too much loss of draft as well as creosote problems eventually leading to a chimney fire, if you can manage to keep your stove lit.
Do you have to use triple-wall stove pipe?
Triple-Wall Stove Pipe Installation According to building codes, there must be a 2-inch clearance around your double- or triple-wall chimney pipe. In mobile homes, you must use a triple-wall chimney pipe.
What is the purpose of double wall stove pipe?

What type of stove pipe do I need?
According to CBMQ.com, it should be at least 24-gauge sheet metal or thicker -- the lower the gauge, the thicker the metal. Typical code requires that single-wall stove pipe maintain at least an 18-inch clearance from any combustible material.
How far can you run stove pipe horizontal?
The horizontal section of the uninsulated stove pipe should not be more than three-quarters as long as that section of the flue above the point at which the pipe and the flue connect.
At what temp does creosote ignite?
Creosote can ignite at temperatures as low as 451 degrees F (for context, a fire in your fireplace can burn in excess of 450 degrees F), and even just an 1/8” buildup of creosote is considered enough to cause a chimney fire.
What happens if a wood stove gets too hot?
What Happens If A Wood Stove Gets Too Hot? A wood burning stove that is too hot can cause metal components to become permanently damaged through warping, weakening or cracking.
How hot is too hot for a wood stove?

At least 2 ft (0.6 m) higher than any portion of a building within a horizontal distance of 10 ft (3 m)”
Can you use a single wall stove pipe outside?
No, you cannot use single wall stove pipe outside. It’ll lose its integrity over time, and will not keep the gases hot enough to prevent the toxic creosote buildup. Without the insulating layer, it will cause cold hearth syndrome, and force the smoke back into your home. You need a Class-A chimney to vent outside.
How much clearance do you need for a single wall pipe?
It's more than just a question of "touching", and single-walled pipe may have clearance requirements of 18 inches. Double-walled pipes are less, maybe 6 or 8 inches.

Can you use single wall pipe in a chimney?
Having said that, single-walled pipe is probably not a good choice for the outside chimney. The concern is not so much heat causing the house to catch on fire (because you must maintain the aforementioned clearances), but that cold outside air will cause the exhaust gasses to cool, which will make it hard for the stove to vent properly. You want the hot exhaust gases to pass up through the chimney quickly, but if they are cooled once they exit the building you can get the colder gases trying to sink back into the stove. Poor draft leads to smokey, hard-to-start fires, creosote buildup, and possibly flue gases backing up into the room. Just did some quick research and it turns out that both single- and double-walled stovepipe are only permitted indoors. When you transition to the outside through an insulated thimble you must use "Class A Chimney", which is an insulated product.
What type of pipe is used for stoves?
Single-wall is definitely the most common type of stove pipe used in installations today. Now that you know more about single-wall and double-wall, you can make the decision for your installation. It is important to choose the one that makes the most sense and is going to be the safest option for your home.
Why use double wall pipe in mobile home?
The reason why you must use double-wall pipe for a clearance of 18" or under is because it is air insulated. The outside of the double-wall pipe does not radiate heat like single-wall does. The air insulation also allows your wood stove to perform better.
Why is creosote minimized in double wall pipe?
The reason why creosote is minimized when using double-wall pipe is because the flue heats up faster and it stays hotter for a longer period of time. Double-wall pipe also does not have as many options in size, currently we offer only 6", 7" and 8" diameters for this type of pipe.
Why is air insulation important for wood stoves?
The air insulation also allows your wood stove to perform better. Performance of your stove increases because the flue will have a higher and consistent temperature with double-wall verses single-wall. While double-wall costs more than single-wall, you could actually be saving more over-all when considering the increased performance of your stove.
Is single wall pipe better than double wall?
The main benefit of single-wall pipe is that it is less costly than double-wall pipe. Single-Wall pipe effectively radiates heat back into your room and you can also install a heat reclaimer. A heat reclaimer forces air out from the chimney and can be installed 12"-24" above your wood stove.

Is single wall stove pipe safe?
No, a single wall stove pipe is not safe comparing to a double wall stove pipe or chimney pipe for a chimney installation . As it is a one-layered simple black painted pipe without any internal air-cooling system, it fails to keep the high temperatures inside the pipe. That causes damage to the nearly attached materials.
Is double wall stove pipe better for fire?
A double wall stove pipe is more durable to high temperatures. It has an internal air-cooling structure. So while blowing off the air through the pipe it cools off the outside of the pipe. On the contrary, a single wall stove pipe becomes too hot and maintains the temperature throughout the pipe. Yet whether it is a single wall or double wall stove pipe, the main reason for a chimney to catch fire is the lack of clearance and stored creosote. If the creosote on the chimney wall becomes ⅛” to ¼” and has air blowing at 451 degrees Fahrenheit or hotter, it has the possibility to catch fire.
Can I run a wood stove pipe through a wall?
You can run a double or triple wall stove pipe through a wall if necessary. But stove pipes are designed to be used in an interior property.

Why do stoves have double wall pipes?
Yes, they cost a bit more but they will last a lot longer than their counterparts. Double wall stove pipes also have better insulation, which helps to keep the flue gasses warmer.
When to use Class A insulated pipes?
These insulated pipes are used when there is no masonry chimney available or a closer clearance to any combustibles is needed.
How does an EPA stove work?
With an EPA stove, the heat that comes off the pipe isn't a substantial amount. Unless the stove is wide open, there's not much heat coming off of it, there is enough to cool the flue though. When I clean a flue that has double wall, it's much cleaner, often very little build up. If it's not needed for clearance reasons, I wouldn't bother with it due to the expense. If you go with single wall, get the 22ga factory crimped pipe, it will last many,many years.
What is the purpose of an outer wall?
The purpose of the outer wall is simply a heat shield, whether you need to keep heat in to keep the flue warm, or to reduce clearances to combustibles.
Is double wall insulation longer than single wall insulation?
Double wall lasts no longer than single wall. The purpose of the outer wall is simply a heat shield, whether you need to keep heat in to keep the flue warm, or to reduce clearances to combustibles. But once the flue burns or rots through, it's done.
Can a cat stove run with a cooler flue?
I think cat stoves run with a cooler flue correct, the question would be how much are you going to gain by only 4.5 feet of DW pipe, not much I bet, short runs of single wall pipe have little effect on the cooling of the flue.
Is a single wall hotter than a double wall?

Is a double wall longer than a single wall?
Double wall lasts no longer than single wall.
Is EPA stove hot?
I would say it depends on the stove. On a good EPA stove your flue temps aren't going to be very hot and it's heat that you probably want being used for creating draft.
Why do you need double walled pipes?
You have to use double walled pipe when going through walls and floors and what not because the double wall and the space between the pipes cools enough that it can come in contact with wall materials. Single walled pipe would get hot enough to ignite the surrounding materials.
What is a connector pipe?
The pipe on the interior of the house is called a connector. It can be double or single wall pipe. The advantages of using double-wall are closer clearances to combustibles, better drafting, and reduced creosote accumulation. As soon as the flue exits the room, be it wall or ceiling, there must be a thimble or ceiling support box that transitions from the connector pipe to either class A, high temperature pipe or a masonry chimney. The class A pipe can be double or triple wall. What is important is that it meet UL 103HT 2100°F standards. For a lot more information on this question visit www.hearth.com.
Can a fireplace use single walled pipe?
Also, a lot of fireplace type units use a 2 walled pipe that brings in air for combustion through the outside pipe and exhausts hot air through the inside pipe, but that wouldn't be used in conjunction with single walled pipe.
