Rasonic RWH-N12RF(T)-W 12L Instantaneous TG Gas Water Heater (Back-flue) (Cloudy White) Review

Mrs. Wong 13/12/2025

屋企個舊嘅成日忽冷忽熱,幫小朋友沖涼好麻煩。換咗呢部樂信恆溫真係好好多,水溫好穩定,唔再怕燙親佢哋。BBE安排師傅安裝都好快手,讚。👍

Al*******g 06/09/2025

Very happy with this purchase. The misty white design is clean and minimal, perfect for our new flat. The constant temperature control is a huge upgrade. Delivery from BBE was next-day too.

K. T. Mak 16/12/2025

The ±1℃ temperature accuracy is legit, thanks to the Japan-made CPU. The smart segmented flame control is also a great feature for efficiency. A solid piece of engineering for the price.

Mr. Lee 01/11/2025

年紀大,最緊要安全。見到有60分鐘自動熄機功能就即刻買。出水夠熱又穩定,用得好放心。網站落單好方便,送貨準時。

Ci****o 21/11/2025

The anti-wind feature actually works. My old heater kept shutting off on windy days. This one is much more reliable.

Er****m 10/08/2025

It works fine, but the "misty white" is more like a light grey/off-white. Also a bit bulkier than I imagined.

Mi*****n 25/08/2025

Does the job perfectly. Stable hot water. 😊

Ah**i 17/02/2026

夠熱,水力OK,無投訴。

Em******g 04/01/2026
