What must a hot water supply boiler be completely filled with?

• A. Water
• B. Steam
• C. Air
• D. Gas

Answer: (A)

A hot water supply boiler must be completely filled with water to operate correctly and safely. The primary function of this type of boiler is to heat water, which is then distributed for use in various applications, such as heating systems or domestic hot water supply. Filling the boiler with water ensures that the heating elements are properly submerged, allowing for efficient heat transfer and preventing issues like overheating or damage to the boiler components. When a hot water boiler is filled with water, it can maintain the necessary pressure and temperature to produce hot water effectively. The presence of water also helps to prevent the formation of steam bubbles that could result in a potentially hazardous condition, such as water hammer or a loss of pressure. Therefore, it is critical for the proper functioning of the hot water supply boiler that it is filled entirely with water.
