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

Ms. Kwok 18/01/2026

The fast-heating feature is a real game-changer. My old water heater took forever. Now I can get a hot shower in minutes. The 24L capacity is just right for my family of three.

Mr. Cheung 24/07/2025

The LCD display is very useful for seeing the exact water temperature. The black glass looks sleek, but it's a bit of a fingerprint magnet. Still, a very good product overall.
