This is an comprehensive Informational video following me as I install a new electric water heater. There are some tips and information in this video that you may find helpful, Some people just might find it entertaining. I am not a plumber or an electrician, codes where I live are very relaxed, where you live you might need a permit to do this for all I know.
If you are installing your own electric water heater make sure you know what you are doing, especially when working with electricity. This is a fairly involved job, there is alot that can go wrong and turn a few hour job into a 10 hour job, especially on some installations.
