Flue types

Your choice of fire will be dictated by the type of chimney or flue in your home. If you are not sure then take a look at your roof and cross-reference it with the simple guide below. Don’t worry if you don’t have a fixed flue, there are many gas fires that are available as a Powerflue or balanced flue model and a fantastic range of electric fires.

• 

  Brick Chimney

  A conventional brick chimney is recognisable by a chimney stack with a terracotta pot or gas terminal.

• 

  Balanced Flue

  Balanced Flue fires vent directly outside through a horizontal co-axial pipe (one pipe within a larger pipe). The outer pipe draws air in from the outside and the inner pipe expels combustion gases.

• 

  Pre-Fabricated Flue

  This is an interlocking metal flue tube system, identifiable by a metal flue and terminal on the roof and a metal flue box behind the fire.

• 

  Pre-Cast Flue

  Built from concrete or clay blocks, pre-cast flues provide a rectangular section flue. They can be identified by a ridge vent or metal flue tube and terminal on the roof.

• 

  Powerflue

  Powerflue fires expel the combustion gases directly outside the building through the use of an electronically driven fan unit mounted on the external wall. A sophisticated microprocessor monitors performance and automatically shuts off the fire in the unlikely event of a failure.

• 

  No Chimney or Flue

  If you do not have a chimney/flue and do not want to install a balanced flue or Powerflue product then an electric fire may be the best option for you.
