DEFINITION

Classification: 392/339

With heat storage means:

(under subclass 200) Subject matter under Class 219, ... wherein the heating device includes a heat accumulating medium insulated against heat loss for storing heat to be dissipated at a later time by a process of heat transfer.

(1) Note. See search notes for other heat exchange means and heat absorber without storage of heat to be dissipated at a later time.
