A hot water boiler is a machine that is used to heat water used in a hydronic heating system. Hot water boilers can be used in hydronic heating systems in residential or commercial buildings.
Hot water boilers are essential for hydronic heating systems. These heating systems consist of a hot water boiler, a water pump and baseboards. After the hot water boiler heats the water, the water is then circulated through pipes in the baseboards of each room in the house or commercial building. The heat from the water transfers to the rooms and heats the entire residential or commercial building.
