Rasonic RWH-N12RF(T)-B 12L Instantaneous TG Gas Water Heater (Back-flue) (Black Matte) Review

K. Y. Lam 15/01/2025

Excellent product. The ECO mode is a great feature for saving on the gas bill. The constant temperature control is very precise. Most importantly, the safety features give me peace of mind for my family. Delivery from BBE was prompt.

Mr. Wong 21/11/2024

啱啱裝修完,揀咗好耐熱水爐,最後揀呢部。個煙墨黑色真係好靚,同我個新廁所個vibe好夾。師傅上嚟裝都好快手。出水夠恆溫,唔會再好似舊時嗰部咁一時凍一時熱。滿意!

Be******n 28/05/2025

The smart constant temperature system is impressive, it holds the temp within ±1°C as advertised. The segmented flame control is a nice touch for efficiency. Delivery was next-day. Good tech in a solid package.

Ke*******g 15/10/2024

Impressed by the specs. The Japanese CPU and smart flame segmentation aren't just marketing terms, the response time for temperature change is instant. A solid piece of engineering.

Mr. Ho 20/01/2025

屋企有小朋友,最怕水溫唔穩定會淥親。呢部恆溫真係做得好好,set好溫度就唔會變。個60分鐘自動熄機功能都好安全,唔怕唔記得熄。

P. M. Kwok 05/12/2024

The water heater itself is great, very stable temperature. But scheduling the installation with the agent was a bit slow. Took almost a week. Product is 5-star, service is 3-star.

Th**s 19/04/2025

買俾屋企兩老用。最緊要係安全同恆溫,呢部完全做到。老人家唔怕會燙親。BBE個sales都好有耐性解答我問題。有3年保養都安心啲。

Ah****g 11/03/2025

住高層成日好大風,舊嗰部成日驚死火。呢部話可以抗八級風,即刻安心晒。師傅裝嗰陣都好pro,解釋得好清楚個恆溫點用。

T. C. Wong 30/10/2024

The water heater works well, no issues with the product itself. However, scheduling the installation took a few calls which was a bit of a hassle.

Mi****e 02/03/2025

Very happy with this purchase. The water temperature is stable and heats up fast. Perfect for a quick shower after a long day at work.

Ke********g 11/02/2025

住高層成日好大風,之前個爐成日驚。換咗呢部話可以抗8級強風,用落真係安心好多!👍

T. C. Wong 18/05/2025

Sleek design and very quiet operation. Heats up fast and keeps the temperature steady. No complaints.

Ah**n 08/12/2024

舊嗰部壞咗急住換,呢部CP值好高。出水夠快夠熱,操作簡單,冇投訴。

Mi****e 02/04/2025

部機運作好靜,一級能源標籤希望慳到煤氣費。暫時用落滿意。

Je*******m 28/11/2024

Love the matte black finish! Super chic and modern. Works great too. 👍
