Far-infrared rays, also contained in sunlight, spread throughout the room, heating it evenly, eliminating temperature differences like a hot face and cold feet. It's a light heating system that spreads the warmth of the sun throughout the room. ・Unlike fan heaters and air conditioners, it doesn't use motors, so it doesn't pollute the air, dry it out, or require ventilation or humidification. It also doesn't have any unpleasant odors. It doesn't stir up allergens like dust mites and dust, making it a friend to those with sensitive throats or skin. ・The heating panel has an overheating prevention function and is adjusted so that it doesn't become hot enough to cause burns upon contact. It also has a power cut-off device in case of tipping, so it's safe even if it falls over in an earthquake. It has a silent design that doesn't produce any annoying operating noise, so it's also recommended for bedrooms. ・Size: Width 51 x Depth 23.6 x Height 43 cm ・Weight: Approximately 7 kg ・Power consumption: (High) 800W (Low) 400W, 2-stage switching ・Recommended applicable tatami mats: 8 tatami mats (high insulation housing)
