Beschreibung
Zusammenfassung:	The invention relates to a cold-water-free gas water heater comprising a main machine. The main machine is provided with a water inflow connector, a combustion heat exchange module, a water dischargeconnector and a heat exchange pipe. The heat exchange pipe comprises a water inflow connection section, a heat exchange connection section and a water discharge connection section which sequentially communicate. The water inflow connection section is connected with the head end of the water inflow connector. The heat exchange connection section is coiled on the combustion heat exchange module. Thewater discharge connection section is connected with the head end of the water discharge connector. The water inflow connection section is a continuously sinuous coiler. A hot water storage cavity isformed in the coiler. The volume of the hot water storage cavity is larger than one third of the volume of the heat exchange connection section. By the adoption of the cold-water-free gas water heater, after short halt and res
