Xiaomi has launched the Mijia Smart Gas Water Heater 2 Zero Cold Water 18L in China. It is available for reservation on JD and other major platforms at 2499 yuan ($353), with sales scheduled to start on December 15. The release follows the recent debut of the Mijia Smart Gas Water Heater 2 Constant Temperature Zero Cold Water 16L.
Xiaomi Smart Gas Water Heater 2 Specs
The heater features a compact design with dimensions of 575×365×184 mm. It comes with a full-glass front panel that fits into modern kitchen and bathroom spaces. It runs on natural gas (12T) and operates at a rated gas pressure of 2000 Pa. Xiaomi says this setup ensures stable combustion across various household conditions.
The system supports a rated heat load of 34.0 kW, which helps maintain strong hot water output even in winter or multi-point usage scenarios. It also supports a minimum heat load of 3.0 kW, allowing for finer temperature control during low-flow operations. The supported water pressure ranges from 0.02 MPa to 0.85 MPa, making it suitable for both low-rise and high-rise homes.
Xiaomi has equipped the heater with an 8100 rpm TSI booster pump. The company claims it improves water circulation speed and increases water output by up to 170%. It supports a 120-meter circulation loop and delivers a 15-meter lift, which allows rapid hot water delivery in large homes, including duplexes and villas. The system supports a hot-water production capacity of 18 kg per minute with a 25°C temperature rise.
The heater offers multiple power modes. It consumes 48W during normal shower use, 66W while running the pump, 80W in antifreeze mode, and up to 114W in boosted shower mode. It supports zero-cold-water functionality by preheating water in the pipes, reducing wastage before showers.
Connectivity features include Wi-Fi (IEEE 802.11 b/g/n, 2.4GHz) and support for Xiaomi’s HyperOS system. The Mijia app allows remote temperature control, scheduling, and smart automation. It also supports smart scenarios such as door-lock linked preheating and automatic coordination with other Xiaomi devices like bathroom heaters.
Xiaomi says the system uses an AI chip to monitor inlet temperatures in real time. The chip adjusts combustion output to maintain a consistent temperature with a claimed accuracy of ±0.5°C.
