Chimney and Fireplace Anatomy and Definitions

Listed below are chimney and fireplace terms and definitions as well as a diagram of a traditional masonry fireplace and chimney.



Anatomy of a Chimney
Chimney Crown – Your chimney crown protects your chimney from water damage entering through small cracks. Without a proper chimney crown- or if you have a cracked one, rain water seeps into the bricks and mortar of your chimney structure. Even minute amounts of water can result in brick flaking, mortar deterioration, and unsightly salt deposits on your chimney. Eventually, the bricks and mortar break up enough that the chimney is no longer structurally sound. 
Flue – A flue is simply a passage for conveying exhaust gases from an appliance to the outdoors. A flue may be a duct, pipe, vent, or chimney. An unlined chimney is technically a flue, even though an unlined chimney is a fire hazard.
Flue Lining – For a safe flue, a lining must be used to ensure minimal accumulation of flammable debris. This lining should be stainless steel or speci…

Choosing the best wood for your fireplace or wood insert

If you burn wood to heat your home you undoubtedly have an interest in choosing woods that are clean-burning and productive in terms of heat produced. You will get the best results and generate more heat per wood volume when burning the highest density (heaviest) wood you can find.
Dense firewood will produce the highest recoverable British Thermal Units (BTUs), but all wood must be "seasoned" for optimum heat production.The seasoning process is simply a matter of allowing the wood to dry in order to lower the moisture content. Dry wood burns more efficiently, with fewer hydrocarbons going up the chimney. It's estimated that even a mildly wet log loses fully 5% of its available energy vs. burning a dry log. When burning a wet log, a considerable amount of energy is spent driving off the water, which reduces efficiency.
The Best Woods to Burn by Species There are several variable properties in different wood species that affect the chances for sustainable, cleaner heat. T…
