Detailed Description

The following description is made with reference to the accompanying drawings, in which a housing 1, a water tank 2, a metal electric heating tube 3-1, a thin film electric heating tube or an aluminum electric heating tube 3-2, a water pump 5, a water tank water inlet or heating return pipe (or port) 6, a heating hot water pipe 6-1, a domestic hot water outlet pipe (or port) 7, a tap water or cold water pipe 7-1, water 8, an expansion water tank 9, a plate heat exchanger 10, a water switch 10-1, a floor heating 11, a radiator 12, a domestic hot water point 12-1, a water flow sensor 13, a coil pipe 14, a pressure relief and water drain valve 15, an electric three-way valve 16, a water inlet conjoined plug-in type valve body 17, a water outlet conjoined,

FIG. 1 is a schematic view of a horizontal metal and thin film electric heating tube wall-mounted heating furnace, wherein a container with a small capacity and a water inlet is arranged on a water tank flange 19, an electric heating tube is arranged in the container, a coil pipe 14 is arranged outside the container, and a thin film electric heating tube or an aluminum electric heating tube is arranged in a water outlet pipeline for supplying domestic hot water; FIG. 2 is a structural diagram of a plate heat exchanger for domestic hot water, in actual use, both ends of the plate heat exchanger are provided with water inlet and outlet integrated plug-in valve bodies made of copper or plastic, so that pipelines are simplified and the structure is compact; the water sent into the water tank by the water pump stays for several minutes according to different capacities of the water tank, namely, the water is heated for several minutes and is reheated by the thin film electric heating tube or the aluminum electric heating tube, so that the sent water is dozens of degrees higher than that of a directly-heated structure without the water tank; the power usage can be reduced.
