A water heater includes an exhaust hood, a heat exchange module, a main heat valve and a control valve extending downwardly in turn between a case and a plate. Inlet and outlet heads are installed on the two sides at the end of the hot water pipes respectively. Holes are punched on the case and the plate correspondingly to connect intake heads with water supply pipes going through the plate. The outlet head goes through the case and the pin connects with one water-intake hose directly. The control valve has one gas valve, one control switch and one water plate. The gas inlet of gas valve is connected with a gas can. Two pipes are installed on the water plate, which are pin connected with the intake head of the heat exchange module. With low flow capacity, the temperature of hot water output can be adjusted for direct use by a human body without mixing cold water.

1. A water heater comprising:a case comprised of one front case and one back plate and fittings inside an interior thereof;a exhaust hood installed inside the case and near the coping with one vent on the top;a heat exchange module and a main heat valve installed under the exhaust hood, said heat exchange module having an inlet head and outlet head installed on two sides at an end of hot water pipes respectively; wherein holes are punched on the case and the plate correspondingly to connect intake head with water supply pipes going through the plate; wherein the outlet head goes through the case and a pin connects one water-intake hose directly said water pipes having considerable flexibility; and wherein the ignition module is installed on one side of main heat valve;a control valve installed under the main heat valve, said control valve being comprised of one gas valve, one control switch and one water plate; wherein a gas inlet of said gas valve is connected to a gas can; wherein pipes are installed on the water plate, which are pin connected with the input terminal and output terminal of the heat exchange module, said two pipes having considerable flexibility;wherein low flow capacity the temperature of hot water output adjusts for direct use by a human body without mixing cold water.2. The water heater defined in claim 1, wherein said inlet head and outlet head of the water heater can be installed in any suitable place on the side of the water heater.3. The water heater defined in claim 1, wherein said intake head in the heat exchange module is constructed on the basis of Venturi meter theory, such that a pressure drop of flowing water between the outlet head and the input and output terminals controls the gas valve and the ignition module of main heat valve; wherein, when the water pressure is low, inner flow is adjusted to increase pressure drop of the input and output terminals.4. The water heater defined in claim 1, wherein said suspension components are located on one side of the water heater, so as to suspend the water heater in a proper place.5. The water heater defined in claim 1, wherein said gas inlet of the gas valve and gas are further comprised of a connector at a connecting point.6. The water heater defined in claim 1, wherein said gas inlet of the gas valve can be firstly installed with a rotational pipe, and then pin connected with the connector and gas can, so as to connect the gas can with the water heater in any suitable place on the side of the water heater.
