A heat storage cabinet for use in solar heating systems and the like. The cabinet is comprised of a pair of open ended shells adapted to be buckled together with shelf like containers of phase change materials to form a tortuous passage for hot air to heat the phase change heat storage material. Intermediate modules may be used between the end cabinets to increase the heat storage capacity. The cabinets may be made of fiber glass with ledges to resiliently receive the phase change shelves for ready installation. Through appropriate top and bottom openings in the cabinet duct work is provided for connection to the building to be heated, hot water tank or the like. The novel construction of the phase change shelves comprises a flat shallow box like construction with internal fins for efficient heat transfer which facilitates installation in the end cabinets and intermediate modules whereby the shelves can be butted up against one another at the connection seams of the cabinet components in the erection of the cabinet in proper registry to form the tortuous passage within the cabinet.
