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

C. H. Lee 18/12/2024

The heater itself works fine, water temp is stable. But the buttons on the control panel are a bit small and feel cheap. The LED display could also be brighter. It's functional, but the user interface design could be improved.

Er****m 22/07/2025

The segmented flame tech is the main reason I bought this. It really prevents the water from getting too hot in summer, which was a problem with my old heater. Stable temperature output. A solid upgrade.

Mr. Wong 30/01/2025

BBE包埋基本安裝好方便。師傅好專業,因為個機背板設計得好,舊機啲窿位都啱用,唔使鑽過,好快搞掂。出水夠熱夠穩定,滿意。

K. Y. Tse 15/03/2025

BBE送貨同安裝都好快手。呢部機真係好薄,慳返好多位,個樣都好modern。最緊要係恆溫好準,沖涼唔會再忽冷忽熱,very good!😊
