If you’re installing new or replacing existing ductwork, you may have questions about the best type of kitchen ductwork. While there are many brands available for installation, there are two main types of pipes that serve different purposes for your installation, single-wall kitchen pipes and double-wall kitchen pipes. Single wall pipes can be installed as long as they are 18 inches from the wall, ceiling, or floor.
If the distance from the fuel is less than 18″, double wall piping must be installed. Double wall piping also requires a minimum clearance of 6″. If your clearance is less, you must make adjustments to allow for the proper wood stove installation.
Once you have determined the clearance, you can choose the brand of stove pipe you wish to install. For more information, check out our article How to Choose a Brand of Stove Pipe. Keep in mind that if you have a clearance of 18″ or more, you can opt to install a single or double wall pipe. If you have a clearance of less than 18″, you should install a double wall pipe.
You can choose between a single or double wall pipe if you have a clearance of 18″ or more. Use our comparison chart below to help you determine which type of pipe is best for your installation.
Double Wall Stovepipe
The advantage of a double wall pipe is that it will last longer, and the draft will improve. In mobile homes, it is always recommended to use a double wall pipe. You should use a double wall pipe with a clearance of 18″ or less because it is air insulated. The outside of a double wall pipe does not radiate heat as a single wall pipe does.
The air insulation also allows your wood stove to perform in better experience. The efficiency of your stove is improved because the chimney temperature is higher and more constant with a double-wall pipe than with a single-wall pipe. Although a double-wall pipe costs more than a single-wall pipe, you can save more if you factor in the increased efficiency of your furnace.
The disadvantage of a double wall pipe is that it is more expensive, but it is also of higher quality and lasts longer than a single wall pipe. With a 0.016-inch thick stainless steel inner wall and a 0.018-inch thick galvanized steel outer wall, the double wall pipe is of higher quality than the single wall pipe. The double-wall pipe also produces less creosote.
Creosote can be extremely dangerous and cause a chimney fire if not handled properly. To learn more about creosote prevention, read our article “What is creosote? The reason creosote formation is minimized with a double-wall chimney because the chimney heats up faster and stays hot longer.
Double wall pipes also offer fewer size options. Currently, we only offer 6, 7, and 8-inch diameter pipes. If your installation requires a 10-inch diameter, you’ll have to use a Durablack furnace pipe.
Single-Wall Stove Pipe
The main advantage of a single-wall fireplace is that it is less expensive than a double-wall fireplace. In addition, a single-wall fireplace effectively reflects heat into the room and can install a heat sink. The heat sink moves air out of the fireplace and can be installed 12 to 24 inches above the wood stove. A single-wall fireplace is an excellent choice if you want to extract maximum heat from your fireplace.
Single-wall chimneys are also available in a variety of sizes. You can install a single wall pipe in a 6, 7, 8, or 10 inch diameter chimney. This pipe is also recommended when the clearance to fuel is 18 inches or more. The single-wall chimney is by far the most common type used today.
Now that you know more about single and double-wall chimneys, you can decide on your installation. Choosing the option that makes the most sense and is safest for your home is important. If you still need to choose a wood stove and are going to make a new installation, we recommend you study all the fireplace and stovepipe options to determine which one best suits your needs. 6″ is the most common diameter we see for chimneys and stovepipes.
Suppose you have a wood stove with a different chimney diameter, such as 7″ or 8″, remember to factor in the cost of that pipe when deciding to purchase a wood stove. Likewise, a larger diameter or thicker chimney, such as a double wall chimney, is something to factor into your budget.
4 Tips for Selecting and Installing Your Wood Stove Pipe
1. Decide what kind of pipe you want to use: single-wall or insulated. Single-wall pipes should be installed at least 18 cm away from combustible surfaces, but they will radiate more heat into your home. Insulated pipes can be installed 2 cm away from combustible surfaces, but they will radiate less heat into your home. The single-wall pipe can be used up to the ceiling, but insulated pipe should be used through the ceiling, attic, and roof.
2. Wooden pipe can be installed horizontally through the wall or vertically through the ceiling. You should try to keep the pipe as straight as possible, so the vertical method is recommended.
3. You will need a ceiling bracket, flashing, rain collar, and cover. These parts can be bought separately or in a handy kit. You also need a baffle to prevent heat from reaching the insulation and beams of your attic.
4. To keep the smoke from the chimney coming out, ensure the pipe is at least 2 feet above the roof. Support straps can be purchased to secure a more than 5 feet high chimney.
