Rasonic RWH-N10RF(L)-B 10L Instantaneous LPG Gas Water Heater (Back-flue) (Black Matte) Review

Em*****o 27/08/2025

Had a few questions about installation in my old building. The BBE customer service on WhatsApp was very patient and professional, confirming all the specs for me. The heater itself works perfectly. A very reassuring purchase experience.

Mr. Ho 06/11/2025

The temperature is stable and the design is nice. My only complaint is the digital display for the temperature is a bit small and not very bright. Hard to see without my glasses on. Otherwise, it's a decent machine for the price.

Je***a 25/12/2025

We renovated our bathroom with a dark, minimalist theme and this heater was the perfect find. The smoky black colour and slim profile look so high-end and sleek. It totally elevates the space. Function-wise, it's flawless.

Pe*****m 31/12/2025

BBE送貨安裝一條龍服務好方便。新屋入伙買俾屋企人用,個恆溫真係冇得頂,小朋友沖涼唔會再咋咋跳話水喉忽冷忽熱。10L出水量夠我地一家四口用,好滿意。

Ja******m 23/09/2025

Bought this purely for the design. The smoky black finish and slim 145mm depth are perfect for my minimalist bathroom. It performs as expected, but the aesthetic is the real winner here.

Mr. Wong 03/01/2026

換咗呢部機一個月,恆溫真係好好多。最驚喜係見到張煤氣單,數字真係細咗。佢個智慧節能mode應該真係work。BBE送貨都好準時,整體滿意。

T. S. Mak 09/12/2025

Installation was rescheduled, a bit inconvenient. The heater works fine, temp is stable. Not sure about the "smart energy-saving" part, seems like just a standard heater. It's okay.

Mrs. Pang 22/12/2025

終於唔使再扭左扭右調校水溫!以前舊嗰部成日驚整親。呢部一開就係要嘅溫度,冬天沖涼舒服好多!個仔幫我上BBE訂,好方便。😊👍

Ah**i 06/07/2025

住唐樓水壓比較細,擔心唔夠力推。好彩BBE有寫明最低水壓要求。師傅裝完試過完全冇問題,出水好穩定,終於唔使再就住就住沖涼。

Al****e 03/01/2026

幫屋企人換,BBE安排嘅師傅好pro,裝得好快手。最緊要係有熄火安全裝置同過熱保護,老人家用都安心好多。恆溫亦都好準,唔錯。

Mrs. Wong 28/10/2025

打上CS問過背出式安裝問題先買,解答得好清楚。部機比舊式嗰啲好好多,開住廚房水喉都唔會搶水,水溫仲係好定!幾好。😊

Er*****n 17/12/2025

Very impressed with the temperature stability. The Japanese CPU isn't just a gimmick; it holds the temp rock-steady even with pressure changes. A solid piece of tech.

K. F. Leung 13/07/2025

約咗師傅上嚟裝,好準時,手勢純熟又快手,裝完仲幫手清走晒啲垃圾,順便教埋點用。服務一流,部機出熱水夠快夠定。

Ke****a 02/07/2025

研究咗好耐,見佢用日本CPU,恆溫控制喺±1℃。用落果然冇失望,水溫好stable。以呢個價錢有咁嘅performance,CP值超高。✨

W. K. Chiu 05/07/2025

The checkout process on BBE was smooth. This heater is perfect for my morning rush. Truly instant hot water, no more waiting around. A great upgrade.
