Abstract
A hot water feeder in which a solar heat collector is used. The feeder has a first heat exchanger for heating a heat medium by solar heat, a second heat exchanger for heating water in a hot-water tank by the heated heat medium, and a heat exchange volume determination unit. The heat exchange volume determination unit calculates the flow rate of the heat medium circulating between the first and second heat exchangers on the basis of the detected temperature of the heat medium fed to the first heat exchanger and the rotational speed of a heat medium circulation pump, and calculates the heat exchange volume on basis of the flow rate and the temperature difference between the detected temperatures.
