Frequently asked questions

  • What is the difference between a chimney and a flue?

    A flue is the channel, pipe, or tube through which gases and smoke travel from the fireplace to the outside. A chimney is, on the other hand, in its simplest definition, the housing that encases the flue.

    There’s a misconception that masonry chimneys are simply made of brick. This isn’t true. The uneven and porous surface of brick provides a space for combustion byproducts to accumulate. This is a major fire hazard. Therefore chimneys are lined with a flue, so the smoke passes over a smooth surface that helps prevent excessive accumulation of combustion byproducts and minimizes the chance of fire. Read our full article on chimneys and flues here.

  • What does open flue mean?

    An open flue typically consists of a pipe to carry combustion gases from the fireplace, whilst fresh air enters the fireplace via the casing. So for safe operation, additional air vents are required in the room where the appliance is installed to re-supply fresh air.

  • Does a chimney need a liner?

    If you are installing a chimney in a newly built property and you want to use it for an open fire, wood-burning stove, or gas fire, then the chimney does need to be lined to comply with document J of current building regulations. In an older property, your chimney doesn’t have to be lined to meet building regulations. An inspection by a chimney professional will tell you if you need to have it lined for safety purposes.

  • How does a chimney work?

    Chimneys operate on the principle that hot air rises above cold air. Hot exhaust gases and ash are lighter in weight than cold outdoor air. The flue directs exhaust from these lighter gases from a fireplace upward to vent outdoors into the atmosphere. Additional air vents are required in the room where the appliance is installed to re-supply fresh air.
