About Twin Wall Flue Pipe
Wood burning stoves have become very popular in recent times, valued by homeowners as an efficient, often cost effective, and certainly renewable heat source. Modern stoves are particularly good at burning wood, especially compressed pulp pellets and artificial logs, in such a way as to meet official environmental standards for clean air.
The trouble many people encounter when looking to install a wood burning stove in their homes is the lack of an existing chimney to safely transfer the gases produced by combustion into the atmosphere. However, this is no longer necessary as there plenty of other, more efficient options.
A twin wall flue pipe, also known as double wall (DW) or high temperature (HT), is a metal tube constructed of two layers of stainless steel, insulated in between to keep gases hot and rising. This avoids the build up of cooling gases within the pipe, which can cause them to back up into your stove and your home. It is for this reason that many homeowners are choosing to retrofit existing chimneys with insulation in the same way.
Installing a twin wall flue pipe has the added benefit of allowing a wood burning stove to be placed virtually anywhere, providing it is adjacent to an outside wall or rooftop and away from combustible materials including household insulation.
Twin wall flues are easy to fit, as the pieces clip together, however these pieces cannot be cut down to size and still function safely, so it is vital to plan carefully. It is also necessary to know and understand building regulations, and to consult the appropriate authorities before fitting.
