Flues & Accessories

A boiler flue is a duct or pipe that carries exhaust gases away from a heating system, such as a boiler. The primary purpose of a boiler flue is to safely vent combustion products produced during the heating process, including carbon monoxide, outside of the building. Boiler flues are typically made of metal, such as stainless steel or aluminum. The material used depends on factors like the type of boiler, the fuel being burned, and local building codes. Boiler flues are usually installed vertically to allow for proper upward ventilation of gases. However, horizontal installations are also possible depending on the design of the heating system and the building's structure. In some modern heating systems, especially those with condensing boilers, the flue may be designed to handle condensation. These boilers extract additional heat from water vapor in the flue gases, improving overall efficiency. It's important to note that specific details about boiler flues can vary based on the type of boiler, local building codes, and regional regulations. If you are considering installing or modifying a boiler flue, it's advisable to consult with a qualified heating professional to ensure compliance with safety standards and regulations.
