What exactly is the gap between a single and double-walled stove pipes? Does the difference, if any, really matter? Well to begin, let’s first explain what a stove pipe is. Basically, inside the simplest terms, stove pipe is an elongated cylindrical tube connected from the stove and useful to release its end products out in to the air. Though it’s no way only an ornamental piece.

Choosing the right stove pipe is important because this device is continually encountered with extreme heat, in fact it is only crucial that you select the one that will withstand this harshest of conditions. Otherwise, it is disaster just waiting to take place.

Just before a stove pipe, it is very important know your own personal purpose. There are several factors to consider such as the specific stove you might be currently using, your requirement for a stove pipe, the wall and ceiling clearance and lastly, the financial aspect.

Types of Stove Pipes:

Wood stove pipes can be found in two types. They’re either venting or vent free, each operating differently through the other. You have to pick which of such two suits your need. Also, most wood stove pipes are made with a 22 or 24 gauge steel. They are either single or double wall construction.

A single wall stove pipe is lighter and generates heat faster. Because of its power to become very hot, it requires at the very least 18 inches of clearance. Involving the two, this is actually the lowest priced.

Moreover, on the downside, single wall construction wood stove pipe has to be replaced from time to time.  It has to be completely changed every 3 to 5 years to make certain its safety and efficiency. While you may be able to lower your expenses by buying one that is cheap, over time, by the need to change a single wall stove pipe every now and then, you might be actually spending more.

Moreover, be suspicious of the varieties of pipe as some didn’t pass code which will be very risky.

Alternatively, a double wall construction wood stove pipe was designed to endure two extremes. Its inner wall is made from stainless steel and black steel for its outer wall.

Further, compared to its single wall construction counterpart, a double wall wood stove pipe is way better insulated. For that reason, it may require as little as six inches of wall clearance and eight inches of ceiling clearance, thus making it ideal in tight and cramp spaces. Its main draw however is the fact that it can be used for long term use, able to last many years.

One problem is that it’s heavier helping to make its installation more challenging. Understandably, because of its durability and clearance, it is greater compared to the single wall pipe. Although, because you will not have to change it every now and then, in the long run, its real price is actually lower than those of an individual pipe.

    *Note: If you have a terra cotta clay chimney
    flue lining, be sure to measure the true length and width of the
    inside of your chimney flue space.

    *If there is a terra cotta clay flue liner, does it protrude out of
    the top of the chimney at least 2 inches? If there are at least 2
    inches and the terra cotta clay is in good condition, you will use
    our stainless steel, terra cotta top plate that has a 1 1⁄2inch edge
    that goes all the way around (like a shoebox lid).

    *If your terra cotta clay flue is in bad shape at the top, you may
    need to just take a hammer and tap all around that terra cotta,
    taking it away to make the surface flat at the top of your chimney.
    In that case, you will simply use the flat top plate that comes with
    our liner kit.



    *Note: If you have a terra cotta clay chimney
    flue lining, be sure to measure the true length and width of the
    inside of your chimney flue space.

    *If it is on the back of the stove, is it parallel with the back of the stove or is it at an angle, like 45 degrees?

    *If it is at an angle you will use an insert stove adaptor (an insert liner kit) rather than a two-part tee with cleanout cap.


    Usually pellet stoves have an exhaust hole id of 3 inches. However, if you are going up more than 15 feet to the top of your chimney you need to use a pipe and/or flex liner that is 4 inches diameter.





    If you are only venting a hot water heater then the exhaust hole diameter is probably 3 inch diameter. If it is 3 inch diameter and you are going up more than 15 feet to the top of your chimney, you must use a 4 inch diameter flexible liner or ridged pipe for proper draft. We also suggest to go ahead and use a 4 inch diameter flexible liner or ridged pipe even if the total length is 15 feet or less.


    Not the depth or any other dimension inside your fireplace.

    Most gas log fireplaces require an 8 inch liner kit or rigid kit. But do not assume that is the case for the gas log fireplace kit you are installing. Obey the requirements for that specific unit that are in your installation/instruction manual.
