A:AnswerHZ is energy efficient compared to BM. overall BM capacity is 25 cubic feet whereas HZ is 24.5 cubic feet. Supposedly HZ has slightly larger freezer. In any event I had to replace my BM after 7.5 years recently with the HZ which was supposed to have same box size but I still had to trim my top cabinet by another 1/16 to 1/8th inch
