The heating speed is impressive, it really takes about 3 minutes as advertised. However, the 23L capacity is just enough for a quick shower if you don't turn the water to max. Overall satisfied with the purchase.

部機得 188mm 真係超薄，裝喺浴缸位都唔覺掗拃。開機 3 分鐘就有熱水，唔使好似以前咁等十幾分鐘，CP值真係好高！BBE 送貨師傅好準時，值得推薦！✨

之前嗰部要等成 15 分鐘，呢部 3 mins 就有熱水。CS salesperson was very patient explaining the system. Packaging was very secure. 👍

German West is a reliable brand. The 3-tank system heats up much faster than my old one, saving me a lot of time. Professional installation too.
