Pay close attention to the install quality of that heater, and be damn sure that Lowe's pulled a permit for it. Lowe's has a history of taking shortcuts with their installations. Whirlpool has some SERIOUS quality control issues with their external components, and most of their parts are proprietary to their brand. My company replaces them constantly for this reason. Just friendly advice.
They got a permit and the county came out and inspected it.
