NOTE: this mainly is a review, not a DIY install guide although it does contain some installation recommendations. Got this Etank 8.0 off Amazon for around 200.00 delivered. Use it when my power is out so my generator doesn’t have to try to heat my 50 gallon house hot water tank which draws 5,500 watts. This tank is rated at 15 AMPS, 1,400 watts. Note that my estimates of providing a full three minute very warm shower was using our very large (6 inch) shower head. I’m sure if someone used a water-saver head it would last much longer. Couldn’t find answers for a lot of questions I had online so I posted this - hope it helps some of you getting ready to go off grid.
