    Why Are Good Chimney Pipe Liners So Important?

    51TQ-3leWLLThe exhaust from a fire, no matter what kind of fuel or type of wood you are burning, can be hazardous to your health. The most important reason why you’ll want the best chimney pipe inserts with your stove is so that these noxious fumes, smoke, and exhaust gases can leave your home in the safest manner possible. That means good stove piping should be able to cleanly seal on its own or be receptive to sealing tape.

    The structure of the flue pipe is also important. As your chosen fuel burns, it creates fly ash that floats within the exhaust itself rather than settling to the bottom of your stove or fireplace insert. As the exhaust is sent to the outside, any bends or crevices in your chimney pipe will begin to collect this ash and soot, eventually accumulating enough to block the output of exhaust. The better the design of the pipe, the better your long-term performance will be.

    The best stove pipe inserts should also be as easy to remove as they are to install. Unlike chimneys that can be easily swept, many homes require a routed pipe design that will need to be cleaned two or three times per year at minimum. Although up a straight chimney is easy enough to clean with specialized equipment, the interior bends are easier to clean if you can quickly access them by hand.

    What Are the Advantages of a Good Chimney Liner?

    The primary advantage of having good piping installed with your stove relates to your home’s energy efficiency. If the stove or fireplace insert that you are using to heat your home is the heart of the house, then the flue pipes are like the blood vessels. A solid, air-tight system will eventually transport heat and exhaust to where they need to go, giving you the money savings that you deserve from an off-the-grid heating system. If there are leaks in the system, then you won’t be heating your home as well.

    A good flue pipe insert can actually increase the length of the burn that you receive within the firebox as well. If you have too much air flowing through your stove, then you’ll end up burning your fire too hot and will go through your fuel too quickly. On the other hand, a low airwash will cause a fire to burn too low and the home won’t get enough heat.

    The best chimney inserts also are made with a double wall design. With an inner and an outer wall, there’s added space for additional insulation to be placed along the length of the chimney pipe and this will help to make your heating system more efficient. You’ll get an outer wall that is cool to the touch for the little fingers in your home without compromising the high temperatures that are needed for the best draft performance of your stove.

    How Do You Find the Best Chimney Liner Kits?

    The first part of the selection process here is to determine the right size of pipe for your stove and home’s structure. Sizes begin as small as 5 inches in diameter, but can be as wide as 24 inches. If your pipe is too large, you’ll impact performance just as negatively as a pipe that is too small. Whatever the requirements of your stove happen to be is generally the rule of thumb to use throughout your entire heating system.

    The best stove pipe inserts will also be insulated in some way or at least allow you to insulate them to increase the efficiency of your heating system. This is particularly important in any joints you may need to install in your venting system. These joints are where you’ll typically need to access your pipe inserts for cleaning and maintenance, so the better they are insulated and receptive to your access, the easier it will be to maintain the system.

    According to UL 103 testing guidelines, you’ll also need to have your piping be able to withstand temperatures of at least 1,400F for a minimum of one hour. Although many of today’s products do so, there are always a few rogue product listings that may not meet this requirement. Always double-check the answers portion of the Amazon listing to make sure your preferred pipe insert will be able to meet your home’s requirements.

    What Are The Best Chimney Liner Prices?

    There are two pricing considerations that you’ll need to consider when installing your chimney pipe. Not only will you need to install piping for your stove, but you’ll also need to make sure that your chimney has been properly insulated per local regulations. All total, the average price that most homeowners will pay for the average chimney upgrade is about $500 including flexible liners, insulation, and piping.

    For pellet stoves where flexible piping is required, the average price for a long enough section of stove pipe is about $100. Small elbow joints and other specific sections you may need start around $25 on websites like Amazon and may be as high as $100 or more.
