[ background art ]
When a consumer purchases a household gas instantaneous water heater, the consumer usually only pays attention to the rising number and the function of rated hot water production capacity, but neglects the minimum hot water production capacity. Therefore, when a common constant-temperature water heater is used in summer, the water temperature cannot be reduced when the water flow is not large due to low water supply pressure, small angle valve channel and the like, and the complaint of overhigh water temperature follows. The gas water heater with the preheating circulation function has a considerable section of hot water remained in the pipe after being preheated, and the water temperature exceeds the required temperature. The complaints of water scalding and sudden high and low water temperature also result from the complaints.
The minimum water production capacity corresponds to the minimum heat load, which are in positive phase. Limited by the influence of correlated factors such as tempering, wind pressure resistance, flameout, condensed water and the like, in order to meet the requirements of safe and reliable national standards, the household gas instantaneous water heater inevitably has a certain minimum heat load value. In a particular consumer environment where the flow of water through the water heater is constant, the minimum heat load determines the magnitude of the hot water temperature rise.
