Common boiler fan faults and solutions

"The fan in a boiler is an essential component for maintaining safe and efficient operation of the boiler. If your boiler fan isn’t functioning properly your boiler might start making unusual noises or lock itself for safety reasons. In this article we’ll be exploring the most common faults with boiler fans and how they can be fixed, to give you a better understanding of how this issue can be resolved if it arises in your boiler.  

Firstly, what is a boiler fan and how does it work?

Boiler fans are designed to generate airflow and maintain the ideal pressure in the combustion chamber, providing an essential air supply for efficient fuel burning. It takes in fresh air and expels waste gases that are produced during the combustion process via the flue pipe, allowing for a clean and controlled burning to generate heat. The fan can have an electric motor or be powered by steam, but in any case, the fan delivers the required oxygen to mix with the fuel. As a result, complete combustion can occur whilst keeping harmful emissions minimised as much as possible. Additionally, the fan helps to remove flue gases, which stops them building up within the system and hindering performance or compromising safety." "
