Claims

[Claims for Utility Model Registration] Fin tube heat exchanger 6 heated by burner 2
The reservoir tank 7 and one passage of the water heat exchanger 8 are connected in parallel through the circuit switching device 9 in the middle of the water circuit 23 that is circulated by the circulation pump 10, and the circulating water flow is further connected to the water circuit 23. Connect the detection switches 11 in series,
- Water supply pipe 1 with oyster water flow detection switch 13 connected in series
2 is connected between the reservoir tank 7 and the circulation pump 10, a hot water supply pipe 24 is connected to the upper part of the reservoir tank 7, and a heating pipe 15, which is the other passage of the water heat exchanger 8, is connected to the upper part of the reservoir tank 7. A heating pump 17 and an expansion tank 18 are connected to form a heating circuit 15, and a circulating hot water temperature sensing element 20a is connected to the reservoir tank 7, water, and water heat exchanger 8, respectively. Hot water is supplied via the controller 21 based on a heating switch signal that drives the heating pump 17 installed in the control box 22, signals from the circulating hot water temperature detection elements 20a and 20b, and a signal from the main water flow detection switch 13. A hot water heater characterized in that it has a combustion control valve 4 whose capacity is automatically switched in multiple stages so that the temperature of hot water sometimes remains constant.
