Abstract: The act of heating water within a contained vessel that is common to most buildings, whether residential or commercial or located in recreational vehicles, mobile homes, aircraft, ships or marine pleasure craft, causes calcium carbonate to precipitate out and settle to the bottom of a heating or fluid containing vessel. The use of ultrasonic transmission within the vessel will agitate the water held within, preventing the normally stagnant hot water from producing calcium carbonate. Other benefits are the cleaning properties of ultrasonic transmission. Thus the internal parts of hot water heaters will enjoy a longer life. This benefit of agitation will also be found when applied to vessels that contain fluids that share similar problems as hot water heaters.
