What is the primary function of a boiler?

The primary function of a boiler is to supply hot water or steam for heating purposes. Boilers operate by heating water, transforming it into steam, or heating the water directly to provide warmth to an environment, such as a residential or commercial space. This process is essential for various heating systems, including radiators, underfloor heating, and hot water systems.

The heating generated by the boiler is critical for comfort in buildings, especially in colder climates where efficient heating is necessary. By producing hot water or steam, a boiler facilitates effective heat distribution throughout a space, enabling effective climate control and comfort.

In contrast, storing gas, ventilating air, or cooling refrigerants are functions associated with different types of mechanical systems, rather than a boiler's primary purpose in heating applications.
