Stainless Steel vs. Aluminum Chimney Liners


A flue or chimney liner is an important component of the modern chimney. Recent tests showed that unlined chimneys allowed heat to move through the chimney so fast that internal woodwork in many homes caught on fire in a matter of hours. Because of these and other tests, liners are now considered an important part of keeping your chimney and home safe, as well as keeping your heating appliances working efficiently.

Purpose Of Chimney Liner

A chimney liner serves several purposes. Firstly, it protects the structure of the chimney from overheating, which protects the masonry and the woodwork surrounding your home. Liners also protect the masonry of your chimney from by-products of burning wood. Gases expelled from burning fires can tear apart the mortar and mortar joints in your chimney and this erosion can cause hazards such as carbon monoxide leaks. Lastly, chimney liners make chimneys work more efficiently. When the flue and liner are sized correctly for your specific chimney it can allow the perfect amount of airflow in your chimney. The result is an efficient wood stove that burns hot enough to heat your home and prevent build-up of by-product.

Stainless Steel Versus Aluminum Liners

Metal liners are growing in popularity in modern chimney installations, and it is important to understand your options before you invest in a specific material. Aluminum liners are durable, but can only be used in gas-burning appliances with lower flue temperatures. The reason for this is because aluminum cannot withstand as high of a heating temperature and if you want your chimney to be protected from heat and combustion you want to go with a material that can take the heat. Stainless steel liners are one of the most recommended on the market because they can withstand an immense amount of heat. Stainless steel can be used in all types of appliances and is typically recommended for wood-burning stoves and fireplaces.

Keep in mind, stainless steel chimney liners are more expensive than aluminum and other materials. However, if you want to invest in a chimney product that will protect your home from combustion and keep your chimney working efficiently, consider investing in the highest quality. A larger investment in the beginning can often cost you less in repairs and damages down the road.

In all cases, it is important to consult with a professional chimney and fireplace company that can visit your home, assess your appliances and recommend a product that is right for you. Many do-it-yourself companies will explain how to install a liner, but if you want your heating appliance products to be installed correctly for optimum performance and safety, consult with a professional company and let them install your liner.
