The invention relates to a vehicle-mounted water heating heater. The vehicle-mounted water heating heater comprises a water tank, first PTC heating bodies, a second PTC heating body, a packaging silica gel layer and a top cover plate; the two first PTC heating bodies are arranged in parallel at intervals; the second PTC heating body is arranged in parallel between the first PTC heating bodies; the head end of the second PTC heating body faces the opposite direction of the head ends of the first PTC heating bodies; an integrated body formed by the two first PTC heating bodies and the second PTC heating body is arranged in the water tank and is connected with the water tank; the packaging silica gel layer is arranged above the three parts; the outer circumferential surface of the packaging silica gel layer is clamped with the inner circumferential surface of the water tank; and the top cover plate covers the top of the water tank. The invention further provides an assembling method of the vehicle-mounted water heating heater. The vehicle-mounted water heating heater is good in insulation effect, convenient to install, high in heating power and high in maintainability. The heating efficiency of the product is improved through the optimal design that the PTC heating bodies are in direct contact with fluid for heat exchange.
