Document Type and Number:
Japanese Patent JP2019045141
Kind Code:
A
Abstract:
To enable stable hot water supply at a set temperature in hot water supply control with a hot water storage tank and an auxiliary heat source.SOLUTION: A hot water supply system includes: a hot water storage tank (4) for storing hot water in a layered state; a first temperature control section (10-1) for controlling a hot water delivery temperature to a set temperature by using first mixing means for mixing supply water with hot water taken out from the hot water storage tank; auxiliary heating means (auxiliary heat source 14) for heating part or all of the hot water taken out from the hot water storage tank and caused to flow in through the first temperature control section; a second temperature control section (10-2) having second mixing means for mixing the hot water heated by the auxiliary heating means with the hot water caused to flow in through the first temperature control section; a first temperature sensor for detecting a temperature of the hot water on the upper layer side of the hot water storage tank; and a control section (8) for selecting either one of the first temperature control section or the second temperature control section on the basis of a detection temperature obtained by the first temperature sensor to cause the selected temperature control section to prepare operation and stopping water supply or mixing of the hot water in the other temperature control section.SELECTED DRAWING: Figure 1
