Does a taller chimney draft better?

Obviously in a chimney fire, the wood is the fuel and a match is the flame so the air providing the oxygen comes in the form of the draft. The reason that a taller chimney creates a better draft is really rather simple as the higher up in the atmosphere the chimney reaches, the greater the differential pressure.

Does rain come down the chimney?

Should unused chimneys be capped?

A: Unused flues should be capped at the top, to minimise rainwater ingress. But it is important to maintain a flow of air through a redundant flue to prevent dampness problems in the chimney stack itself, the chimney breast where it passes through the loft space, and in the rooms below.

How can Backdraft be prevented?

Which wood produces the most creosote?

In general, hardwoods like oak, ash, and beech are more difficult to ignite, but they last a long time. Softwoods like fir, pine and cedar make more smoke, and therefore more creosote. That said, these evergreens contain fragrant resins and oils that easily ignite and are perfect for kindling.
