Rasonic RWH-N10RF(T)-W 10L Instantaneous TG Gas Water Heater (Back-flue) (Cloudy White) Review

Gl******o 19/12/2025

The slim design is perfect for our small bathroom. Fits the minimalist vibe we were going for. The constant temperature control is a huge upgrade from our old place. BBE delivery was on time. Very satisfied with this purchase. 👍

Mr. Kwok 22/10/2025

舊嗰部成日忽冷忽熱,終於換咗。呢部樂信恆溫真係做得好好,出水溫度好穩定,小朋友沖涼唔會再乍乍跳。BBE安排師傅上嚟裝都好快手,成個體驗唔錯。

T. F. Leung 16/11/2025

Technically very sound. The 21 kW maximum heat load provides almost instant hot water. I tested the temperature stability and the ±1℃ claim holds up. A solid piece of engineering for the price.

Sa***p 08/02/2026

The installer arranged by BBE was very professional. He was on time, worked cleanly, and explained all the safety features which gives me peace of mind. The unit itself is fantastic.

Al****p 06/11/2025

Impressed with the specs and it delivers. The temperature is incredibly stable thanks to the Japanese CPU. No more sudden cold shocks. The slim profile is a major plus. Great buy.

Mr. Lam 24/11/2025

揀呢部主要係貪佢有3年保養同埋一級能源標籤,感覺上襟用啲同慳煤氣費。試過廚房同浴室一齊開熱水都夠力,水溫冇點跌,算係咁。

Mrs. Fung 09/12/2025

仔仔買俾我,操作好簡單,一較就係嗰個溫度,唔使驚燙親。出熱水好快,冬天沖涼舒服好多。最緊要有熄火安全裝置,用得好放心。

S. L. Ma 09/07/2025

部機本身OK,恆溫大致準確。不過約師傅安裝有少少混亂,搞咗幾日。同埋點火下下都幾大聲,嚇親屋企隻貓。整體嚟講不過不失啦。

Mr. Kwok 31/12/2025

用咗一個月,特登睇返煤氣單,真係有平到少少。一級能源標籤果然唔係流嘅。恆溫功能就唔多講,同之前啲review一樣,好穩定。

Da********g 25/06/2025

最大嘅改善係廚房開熱水洗碗,老婆喺廁所沖涼都唔會再搶水,水溫完全冇變過!解決咗我哋屋企一大難題!😂 送貨都好準時。

Ms. Wu 22/08/2025

部機係唔錯,恆溫好準。但係夏天想用暖水沖涼時,發覺最低都要35度,有時覺得熱咗少少。如果可以再低幾度就perfect。

Ca*y 22/12/2025

Simple, sleek and works perfectly. The instant hot water is a lifesaver on cold mornings. ✨

Ca******e 29/12/2025

部機白色好靚,又夠薄身,完全唔阻埞。恆溫功能一流!✨

Ah****g 18/09/2025

CP值好高,恆溫準,夠熱。送貨快。無投訴。

Ah**t 18/10/2025

Works as advertised. Hot water is stable and consistent.
