Vertical indoor fan heaters feature a vertical tower design, typically 80-120 cm in height. They incorporate ceramic heating elements and a centrifugal fan system, with a wide-angle air guide grille on top. While possessing a modern aesthetic, they require approximately 0.3 square meters of floor space.
The forced convection system is the core technology of vertical indoor fan heaters. A PTC heater heats cold air to 50-65°C, which is then circulated by a turbine fan at a flow rate of 3-5 cubic meters per minute, achieving even temperature distribution throughout the room.
A vertical indoor fan heater can raise the room temperature by 5-8°C in a 20 square meter space within 15 minutes. However, continuous operation can cause a 10-15% drop in relative humidity; therefore, it is recommended to use it in conjunction with a humidifier. Its noise level is approximately 45-55 decibels, making it suitable for living rooms and other public areas.
