ounting a three-kilowatt heating rig directly overhead in a high-humidity room might give any prudent electrician pause. Xiaomi has opened pre-orders in China for the Mijia Smart Bathroom Heater 2, aiming to replace three separate, bulky fixtures—main lighting, forced exhaust ventilation, and an auxiliary space heater—with a single ceiling-mounted module.
The chassis houses a graphene heating element pushing up to 3,000 W at peak load, a 1,600-lumen LED panel, and dual inverter fans. The ventilation setup circulates up to 300 cubic meters of air per hour, with the manufacturer claiming it can fully dry out and refresh the room's atmosphere in just 90 seconds. To eliminate the need for fumbling with wall switches using wet hands, the unit integrates dual 24 GHz millimeter-wave presence radars alongside sensors for volatile organic compounds (VOCs), humidity, and temperature. The system automatically detects when someone enters, preheats the bathroom, and initiates a dehumidification cycle once the shower stops. Ecosystem integration covers the Mi Home app, a dedicated wireless wall switch, Xiaomi Smart Connect gateway linking, and Xiao Ai voice controls.
Pre-orders on Xiaomi Youpin and JD.com are listed at 1,117 yuan (around €143). For homeowners in modern builds undergoing renovation, this offers a streamlined defense against persistent dampness, grout mold, and precarious portable fan heaters. However, retrofitting the unit into older housing stock comes with a major caveat: hooking a 3 kW draw in a wet zone up to legacy aluminum wiring risks tripping circuit breakers or worse, making a dedicated high-capacity cable run from the breaker box mandatory.
