Rasonic RWH-N10TF(T)-B 10L Instantaneous TG Gas Water Heater (Top-flue) (Black Matte) Review

Mr. Wong 15/04/2025

舊嗰部熱水爐成日一時凍一時熱,終於頂唔順換咗佢。呢部樂信恆溫真係冇得頂,水溫好穩定,小朋友沖涼都安心好多。BBE安排師傅上嚟裝都好快手,整體滿意。

Pe********g 08/11/2024

It works as advertised, the temperature is stable. However, the ignition sound is a bit louder than I expected. Not a deal-breaker, but something to be aware of. For the price, it's a decent unit.

Mrs. Chan 05/02/2025

屋企人多,之前成日爭廁所。換咗呢部之後,就算廚房用緊熱水,我沖涼都唔會搶水,水溫依然好穩定,出水夠快夠力,解決咗大問題。

K. Y. Lee 10/03/2025

BBE CS 好幫得手,問咗好多installation問題都好有耐性。部機個恆溫function真係冇得彈,沖涼終於唔會忽冷忽熱。個design好slim,好滿意。😊

Mrs. Wong 11/02/2025

The heater itself is fine, temperature is stable. But the control panel buttons are a bit small and not very intuitive to use. Delivery scheduling could also be more flexible.

Mr. Leung 08/03/2025

問過CS先買,確認頂出式啱用。換咗之後水溫真係好恆定,話用日本CPU控制真係有啲料到。屋企有老有嫩,用得安心好多。

Ah**t 19/04/2025

以前用開儲水式,冬天沖涼要就住就住。換咗呢部即熱式真係爽好多!✨ 而且比想像中慳煤氣,個智慧節能 design 唔錯。

Ch*****m 22/01/2025

The smokey black colour is so chic! It matches my new bathroom design perfectly. Super slim body, doesn't take up much space at all. Delivery was next-day too.

Eric 19/12/2024

The ±1℃ temperature control is impressive. 10L/min flow rate is more than enough for my small apartment. Good performance for this price point.

Be****w 28/05/2025

10L出水量好夠力,沖涼好爽!就算屋企人喺廚房開水喉,水溫都唔會點變,呢點要讚!👍

Sa*****m 22/11/2024

The smokey black finish gives my bathroom a very modern aesthetic. Super happy with this purchase.

T. C. Ho 05/10/2024

Bought this for my rental unit. My tenant said it works perfectly. A reliable and safe choice.

Al***u 30/12/2024

Works as expected. The hot water is consistent and the pressure is good. Great value.

Mr. Lee 15/01/2025

送貨快,安裝快。即開即熱,水溫穩定,慳返好多時間。

Ah****g 29/05/2025

恆溫好得,夠熱,冇投訴。送貨快。👍
