A method of combining electric heating with a wood-heated masonry furnace is provided. The masonry furnace has an outer jacket (1) and at least one fire chest (5, 6) arranged therewithin for burning the wood. Cheek conduits (8) between the outer surface of the fire chest and the inner surface of the outer jacket, are provided. The conduits are connected to the fire chest (5, 6) at one end and to a flue (9) at the opposite end. At least one electric resistor element (13) is installed inside the furnace. In order that electrical heating could be easily combined with any existing masonry furnace, holes (14) are drilled in the fire cover (10) of the furnace and the at least one resistor element (13) is arranged to hang from the fire cover (10) in the air space (8, 16) inside the furnace.
