Types of Chimneys
When it comes to installing a chimney for a gas boiler, there are two main types to consider: coaxial chimneys and traditional chimneys. Both have their own set of advantages and disadvantages, so it’s important to understand the differences between the two before making a decision.
Coaxial Chimneys
Coaxial chimneys, also known as balanced flue systems, are becoming increasingly popular for gas boilers. These chimneys are designed to extract air from the outside and expel the combustion gases through a single concentric pipe. The inner pipe carries the flue gases out of the building, while the outer pipe brings in fresh air for combustion. This design minimizes the risk of backdrafting and ensures efficient combustion of the gas.
One of the main benefits of coaxial chimneys is their space-saving design. Because they only require a single pipe for intake and exhaust, they take up less space compared to traditional chimneys. Additionally, coaxial chimneys are sealed systems, which means they are less susceptible to leaks and drafts.
Traditional Chimneys
Traditional chimneys, on the other hand, are the more classic option for gas boilers. These chimneys consist of a single pipe that carries the flue gases out of the building. Unlike coaxial chimneys, traditional chimneys rely on the natural buoyancy of hot air to draw the combustion gases out of the building.
While traditional chimneys have been used for decades, they do have some drawbacks. One of the main concerns with traditional chimneys is backdrafting, which can occur if there is insufficient draft or if there are obstructions in the chimney. This can lead to the build-up of carbon monoxide and other harmful gases in the home.
Which Is Right for You?
Choosing between a coaxial chimney and a traditional chimney ultimately depends on your specific needs and circumstances. If you prioritize space-saving design, efficiency, and safety, a coaxial chimney may be the best option for you.
