摘要： A direct-contact type hot water heater includes a perforated plate having a slope allowing water to flow down from its top apex toward its lower surroundings along both or all sides of the slope in the form of a water film. The perforated plate is provided with a number of apertures capable of forming the water film by surface tension. An endothermic material is arranged in a state where it does not project from the lower surface of the perforated plate.
