This series of posts will help familiarize you with your chimney, starting at the most visible part, the firebox, up to your roof and even the parts below you may not have noticed before. We will help you understand the lingo, and explain each part of the chimney so that you can make informed decisions in the event that you need an estimate or repair.
A chimney is a structure that provides ventilation for hot flue gases or smoke from a boiler, stove, furnace or fireplace to the outside atmosphere. Chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into the combustion in what is known as the stack, or chimney, effect.
While the chimney may appear like a simple device, there are many parts to a modern chimney, as you can see in the diagram on the left.
A chimney’s sole purpose is to provide a way to safely heat the inside of your home without letting the gasses and smoke from the fire escape into your home.
Because your chimney plays such an important role in the safety of your home heating, we recommend familiarizing yourself with it and having an annual chimney inspection and cleaning done.
