Another object is to provide in such a percolator a plurality of flat heating sections which can be easily cleaned and replaced or repaired if necessary. Another object is to provide an improved percolator design which is shaped to distribute heat in a predetermined manner :and which is shaped so as to create a natural flow of the liquid being heated within the percolator. Another object is to provide a percolator of a design in which there is little likelihood of trapping condensate therein.
