Xiaomi has announced a new version of its Mijia Smart Gas Water Heater 2, bringing smarter features, faster heating, and a more compact build to households in China. The Constant Temperature Zero Cold Water 16L edition promises reliable, on-demand hot water with seamless smart home integration.
Mijia Smart Gas Water Heater 2 adds app control and automation

This upgraded Mijia Smart Gas Water Heater 2 offers several improvements over previous models. One of the headline features is zero cold water startup, allowing it to preheat at the press of a button or even automatically when triggered by water level. Through the Xiaomi Home app, users can control the heater remotely, set heating schedules, or link it to HyperOS Connect for full smart home automation.
For instance, the system could begin heating water the moment you unlock your smart door lock or turn on a connected light. It’s a small quality-of-life upgrade that adds genuine convenience.
Compact, efficient, and ready for tall buildings
Under the hood, Xiaomi has equipped the new heater with a dual-drive water servo that helps maintain a stable water temperature within ±0.5°C a detail that matters during showers or while filling a bath. The integrated TSI booster pump is designed to keep pressure steady, even in high-rise buildings.
Here’s a quick look at what the new model offers:
- Constant temperature ±0.5°C with dual-drive servo
- Zero cold water startup
- Remote app control + HyperOS Connect support
- Compatible with smart home triggers
- Quiet operation at 45 dBA (CQC Level 1 certified)
- Level 2 energy efficiency rating
- 15% smaller than previous Mijia models
- Dimensions: 530 × 360 × 180 mm

Launch details and smart home appeal
The new Mijia Smart Gas Water Heater 2 goes beyond basic water heating. It fits neatly into Xiaomi’s growing HyperOS ecosystem. The unit is smarter and faster than earlier models. It’s also quieter and more compact, making it a strong match for modern homes and small apartments.
For now, the heater is only available in China. Even so, its launch shows that Xiaomi plans to keep pushing its smart home strategy forward one hot shower at a time.
