Thin House, Japan

Another type of kerosene heater functions similar to a radiator, and consists of two parts. Kerosene fuel is stored in a tank and burned outside the home, and the flame is used to heat a fluid which is circulated into the second unit inside the house. In this unit, fans blow across the tubes carrying the heated fluid, and the room is warmed as a result. This type of heater is popular since it reduces the fumes significantly, and also virtually eliminates the chance of a small child or pet accidentally injuring themselves.
Electric heat is typically delivered through units mounted on the walls, such as above the doors to the deck or balcony, rather than through baseboards. These heaters often do double duty as air-conditioners. Thermostatic control and timers are available in most lines. The manufacturers of electric and electronic appliances produce these heaters.
In northern Japan, yukadanbō (床暖房) (literally, floor heater) is a type of radiating heater beneath the floor in some rooms of newer houses, where heated fluids are circulated to provide warmth. The cost is expensive, so sometimes this type of heater is only installed in small rooms like the "clothes changing room". Electric carpets have become popular in recent years.
Finally, a traditional type of heater known as a kotatsu is also still widely used today. The kotatsu can come in multiple forms, but the more common is as an electric heating element attached to the underside of a low table: the table is typically surrounded by a light duvet-like cloth to keep the heat in. This type of table is common in the washitsu.
