There are so many different parts of the fireplace system. You know about the damper system and the firebox, the chimney cap and the mantel. But a section of your chimney that doesn’t always get noticed is the chimney liner. If you haven’t had your chimney liner inspected in a while, you may want to have your technician take a look at the liner to determine what kind you have and whether it needs to be replaced.
What Materials Can Line Your Chimney
The first thing you’ll want to know is what your chimney is lined with. Many older chimneys were lined with clay or ceramic tile, or weren’t lined at all. This is a problem. There are three main reasons that a chimney is lined:
- The liner protects your house and anything combustible near the fireplace from heat transfer
- It protects the interior of your chimney from the acidic byproducts of combustion
- The chimney liner makes the flue the proper size to ensure efficient running of your fireplace
If your chimney is unlined, these protective measures aren’t being met, and your fireplace won’t be running as safely and efficiently as it could be. There are several different types of liners that you can choose to make your chimney safe and efficient.
Types of Liners
But what about clay liners? Why would these not be as good as stainless steel lining? Well, there are several good reasons. Clay liners are less expensive than stainless steel, and perform quite well in an open fireplace system, but there are definite disadvantages as well. Clay tiles don’t absorb and distribute heat during rapid temperature risings that you get while burning a fire. Because of this, the flue tiles can split and crack, and that’s a situation where your chimney could be exposed to dangerous heat that can break down your mortar and cause structural damage.
Another type of chimney liner is a cast-in-place liner, in which a cement-like product is put inside the chimney to form a seamless liner. This is good because it can help an older chimney gain some strength. The problem with this is that installation is tough and costly.
Stainless Steel Liners
When it comes to chimney liners, the best bet is stainless steel. It will work for all types of heating appliances, is very safe in containing the byproducts of a wood fire, and is also very durable. It is also an easy material for your chimney professionals to inspect and clean. If you are going to use stainless steel to line your chimney, however, it needs to be insulated. The best bet for installing and insulating a stainless steel liner is to hire highly qualified chimney professionals.
