Your chimney serves a very important purpose in your home. It directs the smoke from the fire up and out of your home and into the night air. This is important because there are chemicals in that smoke that could cause negative effects to your health and the health of your loved ones. A chimney is designed to do that job very well, and it’s pretty indestructible as well. But just like everything else, time and weather elements
can cause your chimney to break down and that could mean real trouble. Precipitation can have an especially negative effect, both through an erosive effect and through the freeze-thaw cycle. The cold New Hampshire winters cause the precipitation that has settled in the pores of the brick and mortar to freeze, and when water freezes it expands. This makes the pores even bigger, and that can cause the structure of your chimney to become unstable. 
Chimney Liners
Even though your chimney is quite durable, it can use some help to protect it from the corrosive effects of smoke and precipitation. This help comes in the form of a chimney liner. A chimney liner also called a flue liner, is usually made of ceramic, steel, or clay tile and it lines the interior of the chimney. It serves three main purposes.
First of all, it’s obvious that your fire will create some pretty high heat. Without a chimney liner, the heat of that fire would be allowed to get back into your home, and that could create a dangerous situation in which the walls, ceiling, or woodwork around the fireplace could start on fire.
Another thing that a chimney liner does is to keep the chemicals that could damage the mortar away. When you burn a wood fire in your fireplace, the smoke that is released has many chemicals in it. Those chemicals are strong enough to cause major corrosion in the structure of your chimney and can cause instability in the makeup of the chimney.
A chimney liner can also help decrease your energy bills. Studies have shown that a properly sized chimney liner will generate the correct amount of draft, which will help your fire to burn more efficiently. This also means that less heat is allowed to escape through an oversized chimney liner.
