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

Mr. Leung 09/09/2025

買之前問咗BBE CS好多安裝問題,都好有耐性答。換咗呢部機,最大感受係個恆溫,以前舊機成日搶火,水溫忽冷忽熱,小朋友沖涼好牙煙。而家set好溫度就唔會變,±1℃真係好準,安心好多。

Marcus T. 29/11/2025

Very impressed with the specs. The Japanese CPU ensures precise temperature control, and the DC inverter fan is a huge plus for high-rise buildings like mine. Solid build and performance.

Ms. Fong 28/08/2025

The constant temperature is great, no more sudden cold shocks. But the fan is a little noisy during operation, louder than my previous model. Overall it's okay for the price.

Je******g 17/11/2025

有兒童鎖功能真係好好!唔怕啲細路手多多亂咁㩒校到水溫太熱。沖涼時恆溫又夠準,屋企有小朋友嘅話呢個safety feature好重要。✨

Ah**i 27/09/2025

喺BBE買完直接約埋安裝,師傅好準時,手勢好快,價錢都公道。部機用落暫時滿意,恆溫快,希望真係好似佢講咁慳到gas錢。

S. L. Chan 30/08/2025

送貨等咗幾日。部機恆溫做得好好,水力都夠。唯一係點火下下都幾大聲,嚇一嚇,習慣咗就冇嘢。整體滿意。😊

Ah****g 06/11/2025

見佢有1級能源標籤同ECO mode先買,雖然機價唔算平,希望長遠慳返啲煤氣費啦。出熱水都快同穩定嘅。

Be****o 08/11/2025

Bought this for my rental property. Rasonic is a reliable brand and the 3-year warranty is a key factor. Good value for money.

K. Y. Mak 05/01/2026

Fits perfectly in our small bathroom. The slim 150mm design is a huge plus for saving space. Delivery from BBE was fast too.

Alex P. 09/01/2026

The digital display is clear and user-friendly. Setting the temperature is straightforward. Good UI design.

W. K. Chiu 21/01/2026

The auto shut-off feature after 60 minutes gives me peace of mind. Feels much safer than my old model.

Mrs. Ng 05/11/2025

師傅裝好一開即用,水溫好穩定,幫BB沖涼方便好多,唔洗再溝冷熱水。👍

Ch*****k 17/12/2025

Sleek design and the cloud white colour is perfect for my bathroom. Works great.

Ev***m 04/11/2025

比舊機靜好多,點火冇乜聲,出熱水都好快。換得好值。😊
