Product Description Product Features: 2-in-1 Cooler and Heater: Integrates cooling and heating functions, it not only lowers room temperature in the hot summer but also provides a warm and comfortable environment in the cold winter. Wall-mounted Design: Easy to install and space-saving, this heater is ideal for heating poorly ventilated rooms (such as sunrooms, doorways, and hallways). Also suitable for desktop use. Energy Saving: When the room temperature reaches your set target temperature, the heater will automatically switch to constant temperature mode.
