The upper ends of the heating hot water tank body 7 and the domestic hot water tank body 8 are also provided with a transmission mechanism 23 for simultaneously driving the heating hot water tank body 7 and the domestic hot water tank body 8 to mix the internal hot water evenly. The heating hot water tank body 7 is located on the right side of the domestic hot water tank body 8; The impurity removal mechanism 24 includes a driving component 241, a medicine adding component 242 and a medicine adding component 243. The medicine adding component 242 is connected to the medicine adding component 243. The medicine adding component 242 and the medicine adding component 243 are each provided with two groups and are respectively located on the heating hot water tank body 7 and the domestic hot water tank body 8; The driving assembly 241 is installed on the domestic hot water tank body 8 and is connected to both sets of medicine adding assemblies 242 .

[0026] The manufacturing method of the heating coil 11 is as follows: a metal foil is spread flat on a processing platform, a heating wire is then laid on the surface of the metal foil, and an aluminum foil tape is then adhered to the surface of the metal foil to cover the heating wire to obtain the heating coil 11; The heating wire is a mature technology available on the market. The heating wire is a graphene heating wire purchased from Suzhou Yuanran. It can be the 6th generation nano-carbon wire, the 7th generation polymer nano-mud heating wire or the 8th generation acid and alkali resistant polymer nano-energy heating wire.

[0027] The heating hot water tank body 7 and the domestic hot water tank body 8 are both provided with a liquid level meter and a temperature sensor. The liquid level meter is used to measure the liquid level information in the heating hot water tank body 7 and the domestic hot water tank body 8, and the temperature sensor is used to measure the temperature information in the heating hot water tank body 7 and the domestic hot water tank body 8.

[0028] When the present invention is working, firstly, cold water enters the water heater 5 through the water inlet pipe 14, and enters the heating hot water tank body 7 after being heated by the water heater 5. After the transmission mechanism 23 makes the water inside the heating hot water tank body 7 evenly mixed, the temperature sensor inside the heating hot water tank body 7 detects the heating water temperature, and the temperature sensor inside the heating hot water tank body 7 transmits the temperature signal to the controller 4. The controller 4 controls the water heater 5 to increase or decrease the power to meet the temperature requirement of the water inside the heating hot water tank body 7, and starts the heating hot water pump 12, and the hot water enters each user through the heating hot water outlet pipe 17; After the user's heating water is used, it enters the hot water replenishment pipe 18 through the return pipe of each user, and then enters the domestic hot water tank body 8 through the hot water replenishment pipe 18. After the transmission mechanism 23 makes the water inside the heating hot water tank body 7 evenly mixed, the temperature sensor in the domestic hot water tank body 8 detects the water temperature in the domestic hot water tank body 8. The temperature sensor in the domestic hot water tank body 8 transmits the temperature signal to the controller 4. If the temperature sensor in the domestic hot water tank body 8 measures a temperature lower than the set temperature, the controller 4 controls the second solenoid valve 13 to open, and the domestic hot water tank body 8 replenishes the water through the hot water replenishment pipe 18. The domestic hot water is heated by heating hot water. If the temperature measured by the temperature sensor in the domestic hot water tank body 8 is higher than the set temperature, the controller 4 controls the first solenoid valve 2 to open, and the domestic hot water tank body 8 replenishes the cold water of the water inlet pipe 14 through the cold water replenishing pipe 22 to cool the domestic hot water. When the temperature is adjusted to the set range, the first solenoid valve 2 and the second solenoid valve 13 are both closed, and the domestic hot water pump 10 is started. The domestic hot water enters each user through the domestic hot water outlet pipe 19. If the domestic hot water consumption is small, the excess domestic hot water returns to the domestic hot water tank body 8 through the domestic hot water return pipe 20; In the process that domestic hot water is pumped out through the domestic hot water pump 10 and then enters the user through the domestic hot water outlet pipe 19, heat will be lost and the water temperature will drop. In order to prevent the temperature of the domestic hot water from dropping, a heating coil 11 will be installed on the domestic hot water outlet pipe 19 between the domestic hot water pump 10 and the user to keep the domestic hot water warm.

[0029] When the liquid level gauges in the heating hot water tank body 7 and the domestic hot water tank body 8 show that the liquid levels are simultaneously too high, the liquid level gauges transmit the liquid level signal to the controller 4, and the controller 4 controls the water inlet solenoid valve 1 to close until the liquid level drops to a specified range; if the pressure of the heating hot water tank body 7 is higher than the upper pressure limit of the first safety valve 6, the first safety valve 6 opens to discharge the pressure in the heating hot water tank body 7 through the first safety drain pipe 15 to the water inlet pipe 14, thereby protecting the heating hot water tank body 7 from overpressure; the function of the second safety valve 9 is the same as that of the first safety valve 6.

[0030] After the heating hot water tank body 7 and the domestic hot water tank body 8 have been used for a long time, the driving component 241 drives the adding component 242 and the adding component 243 to add medicine into the heating hot water tank body 7 and the domestic hot water tank body 8 to dissolve the scale in the heating hot water tank body 7 and the domestic hot water tank body 8.

[0031] The present invention uses the return water used for heating as domestic hot water, fully utilizes the heat in the return water, and achieves the purpose of energy saving; when detecting the internal temperature of the heating hot water tank body 7 and the domestic hot water tank body 8, the present invention first mixes the hot water in the heating hot water tank body 7 and the domestic hot water tank body 8 evenly to prevent the occurrence of uneven heat and inaccurate temperature detection; After the heating hot water tank outer shell 71 and the domestic hot water tank outer shell 81 have been used for a long time, scale will appear therein, which will affect the service life of the heating hot water tank outer shell 71 and the domestic hot water tank outer shell 81; therefore, the present invention will regularly drive the drug adding component 242 and the drug adding component 243 to clean the interior of the heating hot water tank outer shell 71 and the domestic hot water tank outer shell 81 through the driving component 241.
