TGC STW12HD(WH) 12L/min Ultra-thin Instant Gas Water Heater Review

P. L. Cheung 05/01/2026

The segmented flame technology is a game changer for Hong Kong summers. Water isn't scalding hot anymore even when it's 30 degrees outside. Very satisfied with the 17-level temp adjustment.

Ga***o 22/01/2026

Decent water heater. The 12L flow is enough for a standard shower. However, the buttons feel a bit plasticky compared to higher-end models. Does the job for the price.

Mrs. Wong 08/02/2026

換咗呢部之後沖涼舒服好多,個恆溫功能做得好好,唔會忽冷忽熱。The technician was professional during installation. 推薦!✨

以前部機夏天水溫太熱,呢部有分段火排真係好好多,35度啱啱好。Packaging was secure and sales were very helpful. 😊

Good product but the CS response was a bit slow. Installation was free as promised though.
