What is the primary function of a boiler in heating systems?

The primary function of a boiler in heating systems is to generate and circulate steam or water. Boilers are integral components in hydronic heating systems where they heat water, which then travels through pipes to radiators or floor systems that distribute heat to various spaces in a building. In some cases, boilers can also produce steam, which is used in similar distribution methods but is primarily applied in applications that require high heat output or pressure.

This process involves heating the water to a specific temperature, thereby raising its energy level, and then using pumps or gravity to circulate this heated water or steam throughout the building, ensuring that the desired indoor temperature is maintained. The effective functioning of a boiler is essential for achieving consistent and efficient space heating.
