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

Be******g 10/04/2025

Impressed with the ±1℃ temperature stability from the Japanese CPU. No fluctuations at all, even when someone else uses water. A solid piece of engineering for the price. The specs on BBE's site were very detailed.

Al***o 28/11/2024

The smoky black finish is super stylish and matches our new bathroom's modern vibe. It's very slim, so it doesn't stick out much. Performance is great, heats up instantly. Delivery was on time as scheduled.

Mrs. Wong 15/01/2025

BBE安排師傅安裝好快手,服務唔錯。恆溫功能真係一流,幫小朋友沖涼唔怕再一時凍一時熱,溫度校喺40度就真係40度,好準確,用得好安心。

林伯 20/05/2025

打電話問過BBE啲操作問題,職員解釋得好清楚。部機黑色幾靚仔,操作好簡單,一個掣校溫度就得。點火快又靜,用得好放心。

Mr. Li 19/12/2024

Replaced an old unit in my rental flat. This Rasonic model is reliable and safe. Good value.

Water flow feels a bit weaker than my old model. Not sure if it's the unit or my plumbing.
