Anki Chimney is the simplest and most cost effective way of building a chimney. Made from Icelandic volcanic rock ANKI is a product that boasts exceptional insulation and longevity and one that is suitable for all fuel types. It can be used for open fires, stoves and boilers for new build or existing properties.

      • Minimum Heat Loss,  Maximum Efficiency
      • Improved Performance For Your Appliance
      • Ideal For Timber Framed & Thatched Properties
      • Better Chimney Draught
      • Less Soot & Tar Build-up
      • Chimney Fire Safe
      • For new build or to add a new chimney to an existing property we recommend Single Module or Block Liners
        For Chimney relining we recommend Round Liners.

      Pumice is a natural material extracted from the heart of the earth to be at the heart of the chimney flue.

      Anki Chimneys are made from volcanic pumice sourced from the Hekla Volcano in Iceland

      The pumice is taken in ships to Denmark where it is formed into chimney products that are capable of performing in the extreme conditions created by a chimney fire and the hardest frosts that we can experience.

      • Resistant to temperature change

      Pumice does not expand or contract with temperature change. This reduces the possibility of cracking and structural damage that can occur with other products.

      • High Insulation Properties

      Pumice is a natural insulator, able to maintain the temperature of flue gases when other products have allowed the temperature to fall below the dew point.
      The high insulation properties also mean that heat is not transmitted to the outside.

      • Lightweight

      Pumice is strong yet lightweight, allowing one person to lift and build the chimney units.

      Due to the nature of the pumice material, Anki chimneys have a life expectancy in excess of 60 years. They are also fully covered by a 15 year guarantee subject to normal usage.

      please note: all installations must be fitted by a qualified Hetas engineer or with building regulation approval.
