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

Pe*******h 22/11/2025

The slim profile is perfect for my tiny bathroom. I also noticed my LPG gas bill seems a bit lower. The smart energy-saving feature appears to be working. Happy with it.

Mr. Leung 29/06/2025

買之前喺BBE問過CS確認係頂出式先敢買。裝完之後用落唔錯,即開即熱,水溫好穩定,好過我之前嗰部舊款好多。CP值算高。

Ja*****m 20/02/2026

Impressed with the constant temperature control. The ±1℃ fluctuation claim holds up. The Japanese CPU really makes a difference. Solid performance.

Gr******n 27/06/2025

BBE安排嘅安裝師傅好professional,裝得好靚仔。個display夠大,屋企老人家都識較溫度。個煙墨黑真係好有格調。✨

Em****g 29/11/2025

Research咗好耐,樂信呢個model個spec同個樣都好吸引。恆溫真係冇得彈,煙墨黑色好靚,同我個廁所vibe好夾。😊

Mr. Leung 25/10/2025

住村屋水壓成日唔穩,換咗呢部機之後恆溫做得好好,唔會再忽冷忽熱。信興代理加埋日本CPU,用得好放心。

Mrs. Wong 20/08/2025

恆溫功能真係好好用,幫小朋友沖涼唔再怕水溫一時凍一時熱。出水又快又穩定,慳返唔少時間。👍

C. K. Lai 27/09/2025

恆溫功能冇得頂,但個溫度調節掣有啲細,有時唔係咁好㩒。不過整體performance好好,所以都值4星。

Mi*****n 14/12/2025

The temperature is stable, which is good. But the water flow feels a bit weaker than my last heater. It's acceptable for the price.

Al****e 01/01/2026

The smoky black finish is very chic and the slim design fits my new bathroom perfectly. A huge upgrade.

T. C. Wong 18/12/2025

Sleek design, the black colour is very modern. Heats up instantly. Very satisfied with this purchase.

Ms. Kwan 17/08/2025

Bought this for my rental unit. A solid, reliable choice that won't give me headaches. Good value.

Er***a 23/07/2025

Works okay, but the ignition sound is surprisingly loud every time it starts. A bit annoying.

Ah**i 22/11/2025

出熱水真係快,水溫又夠穩定,好抵用。

K. M. Ho 13/07/2025

Works as expected. Fast heating and stable. Good buy.
