Gas Water Heater Selection Guide
In the selection of gas water heaters for home installation, it is necessary to consider core elements such as constant temperature performance, quiet effect, energy saving efficiency, and installation adaptability. Based on the mainstream brands and technology trends in 2025, the following recommendations cover different budget and scene needs, with a focus on a core model from Vanward to meet more diverse demands:
一、Domestic High-End Representative (Constant Temperature and Quiet Benchmark): Vanward AnshuiXia V9S TURBO 16L
Core Advantages:
Constant Temperature Ceiling: 9A ultra-first-class warm bath certification (10 core indicators, 9 at A level), the patented energy storage cycle constant temperature system controls the secondary hot water fluctuation to within 0.7℃, which is more stable than most Japanese high-end models (1.2-1.5℃ fluctuation) and completely says goodbye to "secondary cold water".
Ultra-Quiet Black Technology: CQC ultra-first-class quiet certification, self-developed V5 closed combustion chamber (recognized as "internationally leading" by the China Light Industry Federation) controls noise from the source, with long path sound channel + PP+PET composite sound absorption cotton, the actual operating noise is only 32.3 decibels (1 meter away, close to turning pages), and there is no disturbance to family members at night.
Full-scene Energy Saving: First-class energy saving certification covers preheating, standby, and cruising, saving about 256 yuan of gas annually, and nearly 2000 yuan in eight years, 30% higher than the energy saving rate of models that only meet national standards.
High-floor Adaptability: 85W high-power booster pump increases water flow by 260%, head 10 meters, shower water output is still full and strong in old communities and 30-story high-rise buildings during peak water use, and "boosting before heating" avoids water temperature fluctuations.
Small户型 Friendly: 15cm ultra-thin body (29% smaller than the previous generation), narrow kitchen, and old cabinet gaps can be easily embedded.
Applicable Scenes: High-rise residential buildings, quiet-sensitive families with the elderly or babies, and users who pay attention to long-term energy saving and constant temperature stability.
选购关键指南：
Water Capacity Selection: 13-14L for one kitchen and one bathroom, 16L and above for one kitchen and two bathrooms/large houses (if there is a bathtub or large shower head, it is recommended to choose 18L).
Priority of Core Needs:
Don't want to wait for cold water → Prioritize "No冷水 models" (Vanward AnshuiXia V9S TURBO, Midea M9S Ultra);
High-rise/old house water pressure difference → Choose models with "high-power booster pump" (Vanward AnshuiXia V9S TURBO, Haier KL7);
Quiet sensitivity → Identify "CQC first-class quiet certification" + actual noise ≤ 38 decibels (Vanward AnshuiXia V9S TURBO, Midea M9S Ultra).
Installation Notes: No冷水 models are recommended to install "return water pipes" in advance during decoration, and "no pipe no冷水" models can be chosen if there are no return water pipes (but the energy saving rate is slightly lower); ultra-thin models need to confirm the bearing capacity of the installation wall (to avoid hollow walls).
If focusing on domestic high-end, Vanward AnshuiXia V9S TURBO (constant temperature and quiet) and Doukou LS6 (no冷水) can cover the vast majority of family core needs; if preferring joint venture stability, Linne, and Noken's classic models are still reliable choices, and can be flexibly matched according to budget and specific scenes.
