Just thought all you fellow DIY'ers may find this information interesting.
Reasons why a chimney needs a stainless steel liner:
1. Prevents overheating of the chimney and lengthens its lifespan
A chimney that does not have a liner installed is constantly exposed to the gases, heat and smoke from the fire. Over time, these components erode the structure of the chimney. A degenerated chimney could result in gas leaks, higher chances of fire and energy losses.
2. Reduces chance of fire
A chimney liner provides a strong lining inside the chimney that forms a barrier between the fire and the chimney and its surrounding elements. Woodwork and other structures in your home can easily catch fire if they are overheated.
3. Improves energy efficiency
A chimney liner promotes better energy efficiency because it helps the fire to burn brighter while minimizing loss of heat. It helps in maintaining an optimal air flow within the chimney. The need for adding fuel is reduced, and as a result, you can save significant amounts of energy.
4. Makes fireplace maintenance easier
Chimney liners are much easier to clean and maintain as compared to the brick and mortar of a chimney without a liner. As a result, the chimney is more efficient and clean.
5. Available in flexible or rigid material
Metal chimney liners made of stainless steel. They are impervious to problems such as cracks and heat damage, which may be seen in clay and concrete chimney liners.
6. Prevents toxic gases indoors
A fireplace can produce deadly gases such as carbon monoxide as a result of incomplete combustion. It is very important that you ensure that all such toxic gases are safely routed out of your home. In the absence of a chimney liner, these gases have a high chance of leaking back indoors and causing severe health problems in the inhabitants of the household. Severe carbon monoxide poisoning can be fatal. A chimney liner provides a safe outlet for the combustion gases that are produced as a result of the fire and efficiently exhausts these gases out of your home.
7. Reduces soot and creosote buildup
A chimney liner effectively reduces the buildup of soot and creosote within the chimney. These substances are highly flammable and difficult to clean. Chimney liners thereby further enhance safety and simplify chimney maintenance.
