Xiaomi has launched Mijia Smart Bathroom Heater 2, a new integrated ceiling-mounted bathroom appliance that combines heating, ventilation, lighting, drying, and smart controls in one unit. The product has an original price of 1,149 yuan, while its current pre-sale price is 949.45 yuan.
The new bathroom heater is designed for users looking for more automated temperature and air management. One of its key upgrades is a built-in 24GHz dual millimeter-wave radar system, which can detect people and trigger functions such as automatic lighting and ventilation.
Compact Ceiling-Mounted Design
The Mijia Smart Bathroom Heater 2 uses an embedded design for integrated ceiling installation. Its front panel measures 600 × 300mm, while the main body is 598 × 324 × 105mm.

The unit weighs approximately 6.9kg. It operates at 220V with a rated frequency of 50Hz and has a maximum rated power of 3,100W.
The design integrates several smart bathroom appliances functions into a single ceiling unit, helping reduce the need for separate heating, lighting, and ventilation equipment.
Dual-Motor Ventilation System
For ventilation, Xiaomi uses a dual-fan, single-air-duct design combined with two DC variable-frequency motors.
The system provides an airflow rate of up to 300m³/h and supports a 90-second rapid ventilation mode. This allows the bathroom air to be refreshed quickly after a shower or when additional ventilation is needed.
The heater also includes a built-in VOC sensor. Instead of relying entirely on manual controls, the system can monitor indoor air conditions and automatically activate ventilation when necessary.
3,000W Graphene PTC Heating
Heating is handled by a graphene PTC heating element with a rated heating power of 3,000W.
According to Xiaomi’s stated specifications, the system can raise the temperature to 15°C in about one minute under its specified test conditions.
The Mijia Smart Bathroom Heater 2 also uses an advanced temperature and humidity sensing algorithm. Combined with the variable-frequency DC motors, the system can dynamically adjust heating operation according to the bathroom environment.

This approach is intended to provide more responsive temperature control instead of simply running the heater at a fixed output.
24GHz Millimeter-Wave Radar for Automatic Detection
The most distinctive feature of the new bathroom heater is its built-in 24GHz dual millimeter-wave radar.
The radar can detect the presence of people in the bathroom and enable functions such as human-presence lighting and automatic ventilation. This allows certain functions to operate without requiring the user to reach for a remote control or open an app.
The addition of radar also makes the heater better suited to automated smart-home scenarios, particularly when users want lighting and ventilation to respond automatically to their presence.
1,600-Lumen Smart LED Lighting
The lighting system uses a 1,600-lumen LED soft light with a high Ra95 color rendering index.
The light has a color temperature of 5,700K and supports continuously adjustable brightness, allowing users to fine-tune the illumination according to their preferences.
Beyond standard lighting, the bathroom heater supports several additional modes, including natural wind, anti-fogging, and drying. The natural-wind function can be useful during warmer weather when heating is unnecessary but air circulation is still desired.

Multiple Smart Control Options
The Mijia Smart Bathroom Heater 2 supports several control methods.
Users can operate the unit through its built-in digital display panel, the included Bluetooth wireless remote, the Mi Home app, or XiaoAI voice commands.
Once connected to Xiaomi’s smart-home ecosystem, the heater can also support remote operation and smart scene automation. Users can remotely switch the device on or off, set a target temperature, and connect it with other compatible smart-home products.
This gives the bathroom heater a more flexible control system than a conventional wall-mounted or ceiling-mounted heater.
Safety Features
Because the appliance combines high-power heating with electrical components in a bathroom environment, Xiaomi has included multiple protection mechanisms.
The Mijia Smart Bathroom Heater 2 features overheat protection and PTC self-limiting temperature control. These systems are designed to help keep the heating element within a safer operating range.
Xiaomi Mijia Smart Bathroom Heater 2 Price
Mijia Smart Bathroom Heater 2 has an original price of 1,149 yuan, while its pre-sale price is 949.45 yuan in China.
With a 3,000W graphene PTC heater, 300m³/h ventilation, 24GHz millimeter-wave radar, VOC-based air monitoring, 1,600-lumen lighting, smart drying and anti-fogging modes, and Mi Home connectivity, Xiaomi is positioning the product as a multifunctional smart bathroom appliance rather than a traditional standalone heater.

For users already invested in the Xiaomi smart-home ecosystem, its combination of automatic sensing, intelligent ventilation, heating, lighting, and remote control could make it a practical upgrade for a connected bathroom.
