The Hot Water Boiler works on the principle of heating water to a desired temperature for use in heating systems or industrial processes. Fuel such as gas, oil, or electricity is burned in the boiler’s furnace, generating heat. This heat is transferred to water circulating inside the boiler tubes or vessel. As the water absorbs heat, its temperature rises without converting into steam. The hot water is then circulated through pipes to radiators, heat exchangers, or other equipment. The boiler maintains controlled water temperature and pressure using thermostats and safety valves. Essentially, it converts fuel energy into thermal energy to provide a steady supply of hot water.
