Bath temperature is 42 DEG C.User's operation controller 9 before having a bath, controller 9 start water circulating pump 2, and water circulating pump 2 starts running, cold
Water enters heat exchanger 1, after being heated into 42 DEG C of water, by temperature sensor II3, flows to user's water by hot water line 4
Device 6.Due to the influence of original cold water in heat dissipation of pipeline and pipeline, 42 DEG C of hot water is in that the trend gradually to decay flows to user
With water installations 6.When reaching user's water installations 6, water temperature is about between 40-42 DEG C, and water circulating pump 2 should stop transporting at this time
Row terminates warm operation.But since user with water installations 6 does not have hygrosensor, water heater can not know that user is filled with water
Set 6 water temperature.Therefore, water circulating pump 2 continues to run until that the hot water of this temperature is flow at temperature sensor I8, at this time
Water temperature has been decayed to lower than 40 DEG C or so.Water circulating pump is out of service, and warm operation terminates.
From the point of view of this work-based logic, hot water needs to flow to from water heater to be returned with after water spot, needing to continue flow forward
To after water heater, water heater just stops working.Entirely warm operation latter half is all useless, wastes the combustion gas energy of half
Source, preheating time have also been mostly used one times.
