The invention relates to a geothermal-based central heating method using a thermal-increasing heat supply machine unit, belonging to the field of heat supply engineering. The method adopts the soil source or water source thermal-increasing heat supply machine unit to replace a heat exchanger used in the conventional central heating method, uses high temperature hot water supplied by a primary heat supply network as the driving heat source of the thermal-increasing heat supply machine unit, extracts heat from low grade heat source such as thin layer soil or water source, and supplies heat to the user by heating a secondary heat supply network by using the driving heat source and the low grade heat source. The heating method mainly comprises a centralized heat source (which is generally a cogeneration unit, fire coal, a gas heating boiler or the like), the primary heat supply network, the thermal-increasing heat supply machine unit, the secondary heat supply network, an underground embedded pipe, a water source taking well, a recharge well, a heat dissipation end arranged at the side of the user, and accessories connected with the heat dissipation end. Compared with the conventionalcentral heating method, the method expands the forms of the heat sources of a central heating system, thus improving the heating capability of the system and reducing the heating cost.

The invention relates to the technical field of gas water heating stoves, and in particular relates to a heat-storage type gas water heating stove for central heating. The gas water heating stove comprises a closed type heat exchange chamber, a closed type air intake chamber, an overheat protection switch, a temperature controller probe head, a water storage tank, a heat exchanger, a burner, a blower, a water pump, an electromagnetic valve, a water flow sensor, a constant temperature water mixing valve and a connecting pipeline. The gas water heating stove has the technical characteristics and construction of heat absorption in a major cycle, and afterheat absorption in an auxiliary cycle; and the operation and stop of a complete machine is controlled according to signals of the temperature controller probe head and the water flow sensor, so as to keep constant water temperature, secondary constant temperature of the water mixing valve and the reasonable connection of the pipelines to ensure equal pressure of cold water and hot water. By using the gas water heating stove disclosed by the invention, thermal efficiency of the product can be remarkably improved, and equal pressure of cold water and hot water can be ensured; and the gas water heating stove has the advantages of rapid heating speed and large water yield, and is not easily affected by environmental climate when in use. The gas water heating stove can be widely used in places which need hot water supply and heating, such as hotels, guesthouses, bath centers, etc.
