[0031] An explosion-proof door 10 is provided on the upper part of the furnace of the hydrogen combustion reactor 7, and a water-cooled wall heat exchange device 8 is provided on the upper surface inside the hydrogen combustion reactor 7. One end of the water-cooled wall heat exchange device 8 is connected to the return pipe of the floor heating coil system 21, and the other end is connected to the water inlet pipe of the water storage tank 12.

[0032] The four ports of the four-way valve 16 are respectively connected to the cold water inlet pipe 19, the water storage tank 12, the water supply tank 17, and the floor heating coil system 21; the water storage tank 12 is provided with two water outlets, one connected to the floor heating coil system 21, and the other connected to the residential hot water pipe 13.

[0033] The four-way valve 16 is used to connect the water outlet on the water storage tank for installing the filter 14, the cold water inlet pipe 19, the water supply pipe 17 of the water replenishment tank, and the floor heating coil water supply pipe equipped with a temperature control valve 20.

[0034] A fan 3 is provided on the mixed gas storage tank 4, a concentration sensor 5 is provided on the mixed gas pipeline 6 at one side close to the mixed gas storage tank 4, and a filtering device is provided on the residential hot water pipe 13.

[0035] The floor heating coil is laid in a spiral shape, the return pipe is directly connected to the heat exchange equipment in the combustion reactor 7, an insulation layer is provided outside the water storage tank 12, and a protective layer is provided outside the insulation layer. The connecting pipe between the combustion reactor 7 and the water supply tank 17 has a slope, and one end of the combustion reactor 7 is higher than the water supply tank 17.

[0036] The following is a specific implementation example: hydrogen and oxygen are mixed in a certain ratio and burned in a hydrogen combustion reactor 7. A fan 3 is installed at the back of the mixed gas storage box 4, a hydrogen ventilation pipe 1 and an oxygen ventilation pipe 2 are installed on the left side, and a mixed gas pipeline 6 is installed on the right side. The mixed gas pipeline 6 has a built-in concentration sensor 5. The disturbance of the fan 3 can make the hydrogen and oxygen fully mixed, and the concentration sensor 5 can ensure that the concentration of hydrogen is within the safe explosion-proof range.

[0037] The bottom of the hydrogen combustion reactor 7 is a burner 9, and an explosion-proof door 10 is provided on the upper part of the furnace. The upper surface of the hydrogen combustion reactor 7 is a water-cooled wall heat exchange device 8. One end of the water-cooled wall heat exchange device 8 is connected to the return water pipe of the floor heating coil system 21, and the other end is connected to the water inlet pipe of the water storage tank 12. The water storage tank 12 is provided with an insulation layer outside, and a protective layer is provided outside the insulation layer. The water storage tank 12 is provided with two water outlets, one for the floor heating system (see Figure 1 The other can be connected to a water purifier (see Figure 1 The residential hot water pipe 13 connected in the middle is used for a residential hot water system. In the specific implementation process, both water outlets have filters (one is a filter 14, and the filter of the other connected residential hot water pipe 13 is not shown).
