How is steam used to heat buildings?

In steam heating systems, a boiler furnace heats water by means of a gas or oil-fired burner and turns it into steam. The steam travels through pipes to radiators or convectors, which give off heat and warm the room. As the steam cools, it condenses back into water, and returns to the boiler to be heated again.Click to see full answer. Furthermore, how is steam used to cool buildings?Large buildings use machines called chillers to provide the cooling effect. A chiller removes heat from a liquid (typically water). This chilled water is then used to cool and dehumidify the air. Steam heat can be used to boil off the water in order to start the cycle again.Additionally, how are buildings heated? The heat is distributed throughout the building, typically by forced-air through ductwork, by water circulating through pipes, or by steam fed through pipes. A furnace burns fuel oil, which heats air in a heat exchanger, and blower fans circulate the warmed air through a network of ducts to the rooms in the building. Similarly, is steam heating efficient? Steam Radiators Steam heating is one of the oldest heating technologies, but the process of boiling and condensing water is inherently less efficient than more modern systems, plus it typically suffers from significant lag times between the boiler turning on and the heat arriving in the radiators.Why is steam used for heating?Steam also does not change state while it is used as a heating medium, and it gives up heat energy to the secondary medium. During the process, its temperature drops, but the fluid condensate remains at the same temperature. Steam gives up more energy per unit mass than water.
