ABSTRACT:
A heater for the rapid heating of water includes a main body having plural vertical upwardly opening chambers, combined with a molded cover plate that can be removably installed over the upper part of the main body. A plurality of combination heating and chamber partition assemblies extend downwardly from the bottom surface of the installed cover plate and one each of the assemblies resides in a main body chamber, each assembly including a generally flat and vertically elongated partition member and a pair of heating coils mounted to each partition member, one each coil on opposite sides of the partition member, and each partition member cooperates with a chamber to form a first channel for conducting water downwardly and a second channel for conducting water upwardly. There is a water inlet to a first of the chambers and an outlet from a last of the chambers, and the lower edges of the partition members are spaced from the chamber bottoms to form flow paths between first and second channels, and the tops of the chambers are spaced from the bottom of the cover plate to provide flow paths between a channel of one chamber and a channel of an adjacent chamber.
