RASONIC RWH-CT7 Black 24L Unvented Instant Storage (Hybrid) Water Heater (Black Tempered Glass) (Left Flue) Review

Mr. Kwok 15/09/2024

新屋裝修,師傅話呢部機身夠薄,啱晒我個細浴室。BBE送貨準時。開機試用,加熱真係快,液晶顯示溫度好清晰,屋企人連續沖涼都無問題。黑色玻璃面 design 好 modern!

Mrs. Yau 20/11/2023

BBE送貨好快手。買俾屋企老人家用,個液晶顯示夠大夠清楚,水溫幾多度一睇就知,操作夠簡單,佢哋都話好用。個恆溫好好,唔會忽冷忽熱,用得好放心。😊

Ch********n 28/12/2023

問過BBE CS啲尺寸問題先買,服務唔錯。速熱係快嘅,但24公升冬天一家四口用有啲勉強,最後一個要等一陣。不過見佢內膽保用十年,都係揀佢。

K. Y. Fong 11/06/2024

The IPX4 rating and 10-year warranty on the inner tank were key selling points. The unit performs as advertised, heating is efficient and the build quality feels solid. A reliable choice.

P. L. Mui 19/02/2024

Was choosing between this and another brand. Picked this for the slim design and better warranty terms. So far, so good. BBE delivery was on time.

Sarah L. 02/11/2024

Sleek design and the slim profile is a lifesaver for my tiny apartment. Heats up way faster than my old unit. Very happy with this purchase.

K. Y. Cheung 28/01/2024

Bought this for my rental unit. The 10-year warranty on the inner tank is a huge plus for peace of mind. Simple operation for tenants.

Eric 30/10/2024

換走舊式大牛龜,呢部機即刻慳返好多空間。沖涼終於唔使等半個鐘,個速熱技術真係有料到。😊

Mi***o 16/04/2024

部機真係好薄,裝完個浴室睇落大咗。加熱速度OK,夠我一個人沖涼用。整體vibe唔錯,幾滿意。👍

Be*****m 01/05/2024

The black glass panel looks very premium, but it's a fingerprint magnet. Have to wipe it often. Heats up fast though.

Pe********g 05/03/2024

Great water heater. Heats up quickly and the slim design is a huge plus. Delivery from BBE was next-day.

T. C. Ng 12/03/2024

Replaced my old gas heater. This is much safer and the temperature is way more stable. Good upgrade.

Mi*****g 08/08/2023

功能OK,但同價位有其他選擇。純粹貪佢個樣夠靚仔。

Ah**i 08/09/2023

CF話兩邊都有電線位,安裝好靈活,慳返唔少功夫。

Ah***g 20/01/2025

部機好薄身,慳返好多位!出熱水又快,正!👍
