What maintenance issue can arise with high-efficiency boiler fans?

High-efficiency boiler fans are designed to operate under specific conditions to maximize their efficiency and performance. One common maintenance issue that can arise with these fans is the accumulation of debris. Over time, dust, dirt, and other materials can build up on the fan blades and within the fan housing. This accumulation can impede airflow, reduce the efficiency of the boiler, and lead to increased operational costs.

Additionally, if debris builds up significantly, it can cause the fan to work harder than necessary, which may lead to overheating or eventual motor failure. Proper maintenance, including regular cleaning of the fans and surrounding areas, is essential to prevent such issues. This preventive care ensures that the fans can operate effectively and maintain the desired efficiency of the heating system.
