新屋裝修揀咗呢款,3000W真係熱得好快,唔使等好耐。最正係中央式可以駁埋廚房出水位,冬天洗碗都有熱水。BBE嘅CS答問題好專業,幫我confirm咗尺寸先落單,非常user-friendly!

The water heater performs well with stable temperature. However, the Grade 3 energy label means it consumes more power than expected. BBE delivery was very punctual and packaging was perfect, but electricity bill might go up.

Bought this to replace our old leaking heater. The 10-year warranty on the stainless steel inner tank gives us great peace of mind. Excellent safety features. Thanks BBE for the seamless ordering and fast delivery!

呢排天氣凍,好彩換咗呢部熱水爐。智能恆溫做得好好,沖沖下涼唔會突然變凍水,25L兩個人用啱啱好。BBE送貨同裝機一氣呵成,包裝好乾淨安全,體驗超棒!😊

The heater is fine but the installation queue from BBE was way too long. Took almost 5 days to get it installed, which was quite inconvenient. Heating power is decent though.
