The method of claim 10 in which the top surface of the spray plate is one of (a) convex, tapered downwardly at an increasing taper as the distance from a central location increases, (b) segmented with elongate segments separated by relatively shorter segments that are joined to and between the elongate segments, and (c) formed with upwardly facing grooves that terminate at different radial distances from a central core. 12. The method of claim 10 in which the entire distribution plate is made entirely of hydrophobic, nonmetalic, solid material to reduce the transfer of heat from the hot water to the spray plate relative to metal and to reduce mineral encrustation. 13.
