ABSTRACT:
A hot well, especially for food, and a method of heating the well in which an electric heating element is supported beneath the bottom of the well while a heat sink in the form of a U-shaped member formed of a highly heat conductive metal, such as aluminum, is fitted over the well from below. The U-shaped member has a bottom part beneath the heating element and side parts which are parallel to and in intimate heat exchange relation with the sides of the well. Energization of the heating element directly heats the bottom of the well, principally by radiation directly from the heater and by radiation reflected from the bottom part of the U-shaped member. The bottom part of the U-shaped member also absorbs heat from the heating element and, by conduction upwardly along the side parts of the U-shaped member, heat is also supplied to the sides of the well.
