All the stoves in the 7600 series may be enhanced with a top module. The top module may be purchased alone just to obtain a tall stove. A heat storage system with 2 stones (40 kg) may be installed in the top module. A regulation device controls the heat distribution so that either all heat goes to the room or it goes to both the room and the stones.
If the stove is installed with the flue pipe to the rear, an optional 12 kg of heat-accumulating stone may be added to bring the total of heat-storing stones in the top of the stove to 52 kg.
Heat Storage effect:

The heat-accumulating stones are concealed in the top of the stove, shown here in a Morsø 7690.
