An overlapped thermal storage water can comprises a can body, an inlet pipe, an outlet pipe, a pump, a valve and a heater. The water can is characterized that the water can is divided into a plurality of insulation sections around a chamber of the water can by heat insulating layers; top and bottom of the insulating layers are connected with top and bottom of the chamber of the can; overflow return lines are arranged on top. A level regulator is arranged on sidewall of upper part of each layer; an electric heater is arranged below liquid level of central zone; a collector is arranged below liquid level of peripheric zone; bottom of each zone is connected to a blow-off pipe orifice at bottom of the water can; top of each zone is connected to a vent on top of the water can. An interlayer is provided on the thermal storage water can for thermal insulation; and interlayer circulation is achieved by adopting the utility model. The working routine of the utility model is as follows: firstly, heat production; secondly, use of exterior heat or residual heat; thirdly, accumulation of heat; fourthly, use of heat or production of heat; fifthly centralization of heat of layers; finally, duty cycle operation. The product is applicable for all of instant heating liquid circulation systems.
