(under the class definition) Devices consisting of bodies which are so constituted or constructed as to be capable of absorbing quantities of heat energy large relative to their mass or volume and being adapted for use as either a source or reservoir of heat energy. These bodies are frequently the heat sources in so-called "Fireless Cookers" and body warmers.

39, for gas stoves combined with "Fireless Cookers".
87+, 92 and 512, for gas or liquid burning heating stoves or fireplaces having elements against which the flames impinge.
204, and 263, for heating devices including means undergoing a chemical change, other than combustion, to give off heat.
207, for block type body warmers.
246, for dishes having heat accumulators, either liquid or solid. 273.5, for fireless cookers.
375, for heat accumulator bodies incorporated in a liquid heater.
