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-based 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. There are no 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 designed not to become so hot that it causes burns upon contact.
