Coal heat is a heating device that is difficult to replace in remote areas with long-term low temperatures. However, the heat burned in conventional coal stoves is lost in large quantities and is difficult to utilize, resulting in heat energy loss. Summary of the invention

[0021] 1. Add coal blocks to the bracket inside the coal stove and ignite the coal blocks. The heat released by the burning coal inside the coal stove to the outside is absorbed by the heat-conducting copper plate. After the heat-conducting copper plate absorbs the heat, it conducts heat through the heat dissipation fins A and the heat-conducting protrusions, so that the heat absorbed by the heat-conducting copper plate is transferred to the inside of the water tank by the heat dissipation fins A and the heat-conducting protrusions, so that the tap water inside the water tank is heated. Then the hot water inside the water tank is injected into the inside of the geothermal water pipe through the water pipe.

It is heated again by the heat dissipation fins A inside the water tank, thereby realizing hot water circulation, heating the indoor floor, and using the excess heat energy for heating, greatly improving the efficiency of coal-heated heating, and reducing the loss of coal-heated heat energy;

[0022] 2. When the temperature of the heat-conducting copper plate rises, it is transferred to the copper bar, and then to the connecting piece through the copper bar. When the temperature of the connecting piece rises, it transfers the heat to the heat-conducting pipe. The other end of the heat-conducting pipe passes through the bifurcated pipe and is embedded in the geothermal water pipe, making the hot water temperature inside the geothermal water pipe higher, avoiding the temperature drop when the hot water flows into the geothermal water pipe, and achieving the secondary auxiliary heating effect.
