Modified small water heater HLT?

Looking for folks to shoot holes in this idea:
Take a 38-gal dual 4500w element water heater, such as:

Replace the elements with a pair of these:

Cranked up to 170-180, connect it to a 50-amp spa GFCI panel.

Seems like it would heat quickly, and provide really hot water for cleaning. What might I be missing?

well the tank in that Hot water tank is likely made of galvanized steel... people dont generally drink from a hot water tank and its actually recommended to not use hot water from it to cook because of the extra metals and debris that will accumulate in the bottom..(plus they do rust and corrode which is why they eventually leak) I know the description says something about being ceramic lined but you still get a large amount of silt and rust from the water supply unless you prefilter well... even then I'm not sure I would trust it after reading about all the bacteria that thrive in such tanks if the water temp never reaches a high enough temp to kill it...
Just my opinion but even a plastic cooler with an element in it would make better tasting beer than water stored in a galvanized tank.
