SIMPA STW11RM 12L/min Temperature-modulated Gas Water Heater Review

Mr. Wong 12/12/2025

屋企有老有嫩,最緊要係安全。呢部機恆溫做得好好,唔會再好似舊時咁忽冷忽熱,小朋友沖涼都放心好多。BBE師傅上門安裝都好專業 👍。

Mi****e 24/10/2025

The slim design is perfect for my small kitchen. The digital display looks modern and is very user-friendly. BBE delivery was super fast too.

K. Y. Lam 25/02/2026

恆溫功能確實穩定,但係機動排氣個風扇開機時有啲聲,雖然唔係好大但可以再靜啲。整體嚟講不過不失。

Ja*******g 05/08/2025

A solid water heater. The constant temperature control is a game-changer. No more sudden cold shocks during showers. Highly recommended.

Ah****g 11/09/2025

舊嗰部壞咗急住換,見呢部CP值幾高就試下。恆溫功能好實用,呢個價錢有咁嘅performance算係咁。😊

Mrs. Cheung 17/12/2025

Very good value for money. Has all the essential safety features and the water temperature is very stable.
