Xiaomi’s smart home lineup continues to expand in China, this time with a new gas water heater that aims to deliver quieter operation, instant hot water, and tighter integration with HyperOS-connected homes. The company has now introduced a next-generation model built to be more compact and more precise than its predecessor — without sacrificing power.
Xiaomi has launched the Mijia Smart Gas Water Heater 2 Silent Zero Cold Water 16L Edition, a follow-up to the earlier Mijia Gas Water Heater S1. The new version focuses heavily on noise reduction and temperature stability.
As the name implies, Xiaomi is pitching silence as a key selling point. The heater uses nine-layer noise reduction technology and carries CHCT Level-1 Acoustic Quality Certification, which essentially means it has been tested to operate more quietly than typical gas-powered systems. Despite the emphasis on silence, Xiaomi says it has not compromised on performance: the heater promises instant hot water and maintains a steady temperature thanks to a dual-drive water servo system that keeps fluctuations within 0.3°C.
Users can choose from four heating modes — timed, water-controlled, manual, and connected — depending on their routine. The connected mode is where Xiaomi’s ecosystem advantage comes in. The heater supports HyperOS Connect, allowing it to communicate with other Xiaomi smart devices. For instance, homeowners could automate hot water to start flowing when a Xiaomi smart lock is unlocked or manage temperature settings directly through the Xiaomi Home app.
Another highlight is the heater’s size. With dimensions of 520 × 360 × 172 mm, Xiaomi claims the new model is 21% smaller than the previous generation, making it easier to install in tighter spaces or modern apartments where every centimeter counts.
Pricing and availability:
The Mijia Smart Gas Water Heater 2 Silent Zero Cold Water 16L Edition is currently available in China for CNY 2,299 (~$320).
