Pretty easy install, no need to open up the box to connect electrical. You’ll need a 60 amp electrical disconnect box (ten dollars), 1 line of 6/2 wire (2 dollars a foot), a 60 amp double pole breaker ( just above ten dollars), 3 cable clamp connectors (well below 10), Teflon tape for PRV (2), and a pressure relief valve (PRV) (11 to 20) and the fittings to put in the PRV (varies but probably around 25), some cable staples to hang the wire, and some #8 screws to mount the tank and disconnect box.
Inlet/outlet is 1/2 and big box stores around me usually only carry 3/4 PRV. I used a corregated steel pipe connection to the inlet/outlet instead of the supplied compression fitting. The inlet connection kept giving me a small leak, so i had to use some blue blocker + teflon tape to shut it up.
no larger than a phone book , unlimited hot water , cheaper electric bill than standard water heater ,( it only uses electric when hot water is used ).One bathroom, one dishwasher, one washer, one person- hot water all day everyday all the time.
