Gas Fire Flue Types
Your property could have a flue box and a liner, a brick chimney and inglenook or maybe just a flat wall and no chimney at all. With all of these instances there are various options to install a gas fire. The main consideration when choosing a heating solution for your home is to decide if you will use an existing chimney or install a flue system. Using the existing chimney will give you the cheapest installation costs overall and will mean you spend most of your budget on the actual gas fire or fireplace. For each type of chimney or flue system there is a specific type of gas fire which can be installed. Whilst the pictures and information below may be of help to you, the only reliable way of establishing what chimney or flue type you have is to ask a gas safe engineer to visit and perform a survey. This should be done in all cases to check the compatibility of your chimney or flue with the type of gas fire you intend to purchase.
