Claims (1)

[Scope of utility model registration request] In a water heater that uses condensation heat from a refrigeration cycle,
A water heat exchanger for hot water supply in the refrigeration cycle and a water flow rate adjustment valve that automatically maintains the temperature of the water entering the upper opening of the heat storage tank at a substantially constant level are installed in the water channel connecting the upper and lower openings of the heat storage tank. A hot water supply system in which a plurality of temperature sensors that can be switched to each other are attached to the top of the outer wall of the tank, and a selected one of the sensors controls the start and stop of the refrigeration cycle.
