The process of adding water to a boiler is referred to as "feeding." This involves supplying the boiler with water to replace water that has been lost due to steam generation or other operational processes. Proper feeding is essential for maintaining the correct water level in the boiler, which is crucial for safe and efficient operation.

Maintaining the appropriate water level helps prevent scenarios like overheating or damage due to insufficient water, as well as ensuring that the boiler can generate steam as needed for its intended purpose. This process is typically managed through a feedwater system that may include pumps, valves, and controls to ensure that water is added safely and effectively.

Other options such as draining pertain to the removal of water, while blowdown refers to the process of removing a portion of the water and sediment to maintain water quality and concentration in the boiler. Heating, on the other hand, describes the process of increasing the temperature rather than managing water levels.
