What is the consequence of a heavily scaled bank affecting its internal surfaces?

The consequence of a heavily scaled bank affecting its internal surfaces primarily relates to the flow of water and how it interacts with the equipment's systems. When internal surfaces become heavily scaled, the buildup interferes with the normal operation of the unit. Specifically, the scale can restrict the flow of water, leading to an abnormal increase in water levels within the unit. This overfilling occurs because the scale covers essential areas designed for water circulation, which makes it difficult for the unit to achieve proper drainage and can cause the water level to rise above normal operational standards. As a result, the overall efficiency of the appliance is compromised.

Ultimately, when a steam unit is compromised in this way, the risk of operational failure increases, which can lead to safety hazards and damage to the equipment itself. This highlights the importance of regular maintenance and descaling to ensure optimal functioning and to prevent such issues from arising.
