I am getting a challenger cabinet setup and trying to decide between getting a power burner or just keeping my free standing burner I have now. The free standing I have now is 100k BTU while most of the built in top out around 70k btus. I want to fry on it a couple times a quarter, probably two crawfish boils a year (80 qt pot) and several smaller boils through the year. The power burners all run about $1200 plus. I am having a hard time justifying the expense and losing the BTUs. Do the power burners burn more efficiently than the academy free standing units? Anything else to consider other than aesthetics?
