This type of stove was very common in the 1930s through the early 1950s when people were replacing total wood or coal cookstoves with gas or electric ranges. These stoves would fit in the same footprint as a wood/coal cookstove and would still use coal/wood for space and water heating in the winter months (with some limited cooking on top also possible) but the gas/electric side would be the primary cooking stove for the warmer months of the year so that there was no need to light a coal/wood fire in July in order to cook or bake.
