Abstract: A heat exchanger comprising a coil assembly mounted in a broiler used in restaurants for example where the temperature of the broiler is about 500.degree. F., such coil assembly being connected to an intermediate holding tank into which cold water is fed from a public water supply through a downwardly extending pipe in the intermediate holding tank having its discharge opening near the bottom of the tank. An outlet port is located slightly above the level of the discharge opening of the downwardly extending pipe, and a conduit is connected between the outlet port of the holding tank and the coil assembly mounted in the broiler, with a pump connected in this conduit to pump cold water from the bottom portion of the intermediate holding tank to the coil assembly mounted in the broiler. A return conduit leads from the coil assembly back to an inlet port of the intermediate holding tank located in the upper part of such tank whereby water which has been heated to about 100.degree. F. from about 40.degree. F.
