A commercial boiler is a type of heating system used in larger non-residential structures, such as hospitals, schools, and workplaces.  Usually, a pressured system is used to heat water by burning fuel (such as gas or oil) or electricity, creating steam or hot water for heating and distributing hot water throughout the structure. In order to provide heating and hot water when needed, these boilers are frequently connected with intricate pipe systems and are typically bigger and more potent than domestic boilers. These provide benefits such effective heat transmission, lower fuel usage, and the capacity to supply thermal energy, steam, or hot water for a range of uses.

Government policies and regulations that encourage the installation of new boilers or upgrades of existing ones, the availability and affordability of fuels, the rapidly increasing urbanization and industrialization, the growing demand for space heating, the need for energy-efficient heating solutions, and growing environmental awareness are all driving the adoption of modern, high-efficiency boilers with lower emissions. Condensing boilers and high-efficiency boilers are two examples of new technologies that are driving market diversification and making these solutions more appealing. The expansion of the industrial sector, which depends on boilers for a number of processes, also raises demand for these systems overall.
