A method of managing a liquid solvent inventory in a condensing solvent gravity drainage extraction chamber includes growing the extraction chamber by injecting a solvent vapour under conditions which cause at least a portion of the solvent vapour to condense on a hydrocarbon extraction interface at a condensation temperature, then accumulating within the extraction chamber condensed liquid solvent which is draining through the chamber under the influence of gravity, which liquid solvent includes a hydrocarbon rich fluid production layer which is proximal to said extraction interface, and then heating a portion of the extraction chamber from a location near, in and/or above the injector to create a heated zone having a temperature above the condensation temperature without heating the hydrocarbon rich production layer to permit the hydrocarbon rich production layer to continue to drain to a production well.
