Abstract: An electromagnetic heating element for a water heater comprises a cold water inlet (1) and a hot water outlet (2), and further comprises a housing (3) made from an insulation material, a primary heating tube (4), a secondary heating tube (5), and an electromagnetic power coil (6) wound on an outer side of the housing (3). The primary heating tube (4) and the secondary heating tube (5) are respectively provided inside the housing (3). The primary heating tube (4) has a coil structure. An upper end of the primary heating tube (4) communicates with the cold water inlet (1). The secondary heating tube (5) is inserted through the middle portion of the primary heating tube (4). A lower end of the secondary heating tube (5) communicates with the hot water outlet (2). Water enters the electromagnetic heating element from the cold water inlet (1), absorbs heat from an inner wall of the primary heating tube (4), and then enters to the bottom of the housing (3), such that a water level gradually rises. During rising of the water level, the water contacts an outer wall of the primary heating tube (4) and an outer wall of the secondary heating tube (5), and absorbs heat emitted from the heating tubes. When the water level is higher than a top opening section of the secondary heating tube (5), the water flows into a hole of the secondary heating tube (5) under the action of water pressure, and carries away heat emitted from an inner wall of the secondary heating tube (5). The water fully contacts the inner walls and the outer walls of the primary heating tube (4) and the secondary heating tube (5), such that the heat from the heating tubes is completely transferred to the water, thereby improving an energy conversion rate.
