Fosse Fires Ltd is your chimney installation company in Cheltenham, Gloucestershire. Using fires and powerful modern appliances requires a quality chimney to gain the best results. An unlined or old chimney can be inefficient and sometimes dangerous. Traditionally chimneys are completely constructed on site with separate components supplied by different manufacturers. This process is labour intensive and makes it difficult to ensure consistent insulation. This is the unique property that separates pumice from all other chimney materials. The insulating properties of Pumice allow the flue gases in the chimney to quickly reach their optimum temperature enabling the heating appliance to reach its optimum performance shortly after lighting. It also keeps the chimney warmer longer as the heat output of the appliance decreases once again aiding performance and reducing the likelihood of condensation and soot build-up. This offers the user simple and precise fire regulation for lighting,
