住村屋最怕電力唔夠負荷。呢部3.5kW啱啱好,BBE送貨又快。加熱速度比舊式快好多,沖涼終於唔洗就住就住。個Infinity Technic真係得,熱水好穩定。

The 10-year warranty on the inner tank was the deciding factor for me. I contacted CS before purchase and they were very clear about the terms. It gives me peace of mind about its durability.

The heater works fine, but it makes a noticeable humming noise when heating up. Not loud enough to be a deal-breaker, but a bit annoying 😕. Delivery was quick though.

屋企有小朋友,個溫度可以自己校由35度起跳真係好好,唔怕佢哋手多多整到太熱。沖涼都安心好多 😊。

Bought this for a rental unit. The safety features and durable Incoloy heating part are key. A solid, reliable choice.
