The chimney is the engine that drives
the heating system around your house. The more fuel you add to the fire, the
more power the chimney will be able to deliver, and the more draft will be
produced. Draft is a good thing, keeping the smoke from entering the room.
You’ll also need to insulate your chimney to keep the exhaust hot and expel
much of the smoke outside.
Chimneys
work with both stoves and fireplaces. Any heat in your chimney will cause a
draft, which will in turn pull in more combustion air and allow the fire to
burn hotter. This can help you save on energy costs by supplying more natural
heat to your home.
Many
fireplaces and stoves operate on a natural draft. This means that no fans are
necessary to flow the chimney exhaust fans upwards.
However, for a chimney to function as it is intended, it will need to
receive at least one fifth of the total energy produced from heat. If you don’t have a natural draft, the
chimney fan is the only other solution to prevent your chimney from starving of
heat and allow it to function as it should.
