ABSTRACT:
A water heater which comprises a phase change material having a thermal energy capacity of at least about 25 cal/g and having a freezing/melting temperature from about 15.degree. C. to about 100.degree. C.; a source of water, a heating element for heating the water; a heat exchange unit which contains phase change material; and a plurality of heat exchange tubes positioned in the heat exchange unit with the phase change material located between and around the heat exchange tubes which are in heat transfer relation to the phase change material and in fluid connection with the source of water so that the water heated by the heating element flows through the tubes, heats the phase change material and thereafter the heat stored in the phase change material can be transferred to water flowing therethrough.
