Water quality is crucial in boiler operation primarily because poor water quality can lead to scaling and corrosion within the system. When the water used in a boiler contains impurities and chemicals, such as minerals and dissolved gases, these substances can precipitate out and form mineral deposits on the heat transfer surfaces, known as scaling. This buildup restricts heat transfer efficiency, leading to higher fuel consumption and increased operating costs.

Additionally, the presence of dissolved oxygen and carbon dioxide in the water can contribute to corrosion, which damages the boiler's metal components over time, potentially leading to leaks and failures. Maintaining proper water quality through regular testing and treatment helps to mitigate these risks, ensuring the boiler operates efficiently and extends its lifespan.

The other options do not address the primary technical aspects related to boiler operation and maintenance. For instance, focusing solely on the exterior cleanliness or aesthetic aspects of the water ignores the critical internal conditions that affect performance and safety. Similarly, while increasing pressure is a factor in boiler operation, it is not directly linked to water quality but rather to the design and operational parameters of the boiler.
