专利汇可以提供Instantaneous water heater utilizing solar heat专利检索,专利查询,专利分析的服务。并且PURPOSE:To enable to be automatically ignited and burnt even when a three- way valve is changed-over to a storage water heater side by a method wherein a pump and a flow switch are provided in a hot water pipe line, which connects a storage water heater utilizing solar heat with an instantaneous water heater, and said water pipe line is connected through said three-way valve with a water supply pipe line. CONSTITUTION:The flow switch 4 and the pump 5 are provided in the hot water pipe line 3 of the storage water heater utilizing solar heat 2. The water supply line 13 is connected through the three-way valve 6 to the hot water pipe line 3 and also connected through a diaphragm 7 and a flow switch 9 to the heat exchanger 11 of the instantaneous water heater. The numeral 12 expresses a hot water outlet and the numeral 10 expresses a burner. The flow switch 4 is activated by flowing the water therethrough to put the pump 5 in operation and the flow switch 9 is activated by flowing the water therethrough to put an automatic ignition device in operation. The burner is ignited by flowing either the hot water or the supply water by changing-over the three-way valve 6.,下面是Instantaneous water heater utilizing solar heat专利的具体信息内容。
