Rasonic RWH-N12TF(L)-B 12L Instantaneous LPG Gas Water Heater (Top-flue) (Black Matte) Review

Mr. Wong 17/06/2025

BBE安排師傅好快手,服務唔錯。屋企有小朋友,最緊要水溫夠穩定,呢部機個恆溫真係掂,沖涼唔會再乍凍乍熱,12公升出水量夠一家人用。個ECO mode希望真係慳到煤氣費。👍

Al******g 12/10/2025

The smart temperature control is the best feature. The water stays at exactly the set temperature, even when the kitchen tap is on. The DC fan is also very powerful, no worries during strong winds. A solid upgrade.

Ke*****u 06/01/2026

The temperature stability is excellent, the ±1℃ claim seems accurate. My only minor gripe is the control panel display could be brighter and more intuitive. Overall, a great piece of engineering.

新屋裝修,BBE師傅好準時,安裝好專業。特登揀呢部係因為日本CPU同雙重電磁閥,感覺安全啲。個煙墨黑design同我個廁所vibe好夾,滿意。

Mi*****n 20/11/2025

買俾媽咪用,最緊要安全。見到有60分鐘自動熄機同防漏煤氣功能就即刻買。佢話用落水溫好舒服,夠熱又唔會辣親,咁我就放心晒。😊

Mrs. Mak 09/07/2025

舊嗰部用咗十幾年,成日忽冷忽熱。換咗呢部恆溫真係舒服晒,冬天沖涼終於唔使再就住個水龍頭,開幾耐都係咁暖,值得。

P. Y. Ho 30/09/2025

The 60-minute auto shut-off function is a crucial safety feature. It provides great peace of mind, especially for families with elderly members.

C. P. Cheung 09/09/2025

部機身好纖薄,裝完慳返唔少位。煙墨黑色好特別,襯我個廁所style。網站落單好方便,送貨準時。

K. M. Lee 05/12/2025

Heater works fine and the temperature is stable. But the fan is a bit louder than I expected. It's acceptable, but noticeable.

T. C. Wong 22/07/2025

Grade 1 energy label and 3-year warranty are the main reasons I chose this. So far, it's been reliable. A good, solid choice.

Jessica T. 05/02/2026

Love the matte black design! It looks so much better than the old white one. Very sleek and modern. Delivery was fast too.

Be*****m 11/11/2025

Bought this for my rental property. The Grade 1 energy label and 3-year warranty are great selling points. Good CP value.

Sa********g 03/01/2026

部機size啱啱好,唔佔地方。一級能源標籤,希望長遠慳返唔少煤氣錢。CP值高!👍

Ch*****m 12/12/2025
