No Chimney No Problem? Steel chimney systems Pros and Cons

Firstly it is typically easier and much cheaper to install a wood burning stove into a pre existing chimney in most cases. However there are many scenarios where houses have either had there chimney removed or they have not been built with one. It is in these houses when Steel Factory made flue systems come into there own.

It must be considered that a steel chimney system has to play several important roles. These are structure, gas tightness, fire protection, looks, insulation, corrosion resistance and compliance with the building regulations. A typical brick chimney has all of the structure, looks and insulation and in most cases relining the flue will tick the remaining boxes. Making the use of an existing flue much easier and cheaper. In essence a steel chimney must be able to replicate in use a well insulated, lined brick chimney.
