Heating the hot water to supply heat to the heating device meets people's comfort.

[0036] When the solution in the hot water tank is fully heated, the water pump starts to drive the hot water in the hot water tank into the second water inlet chamber 26 through the water inlet pipe 28. After the hot water in the second water inlet chamber 26 is full, the hot water is respectively driven into the first water inlet chamber 21 in the three heating components 15; after the hot water in the first water inlet chamber 21 is full, the hot water is driven into the first core 18 through the first connecting pipe 41.
