This is a Nonomiya-made electric heater ro-dan (furnace platform). The dirt on the fan part will be hidden by the ro-buchi (furnace rim), but for some reason, there are stains like charcoal on the haigata cover (ash mold cover), even though it's an electric heater. It will be somewhat hidden when a ro-gama (furnace kettle) is placed on it, but I don't recommend it to those who are concerned. The electric heater's operation has been confirmed. Dimensions: 42cm square, 16.5cm high.
