Nice unit, works well so far.
Nicely made unit. Clean lines, nice display, lightweight, easy to mount. You'll need a terminal box to wire it up since it comes with it's own pigtail cable (they don't want you to open up the case since it will void it's warranty, apparently; multi breaker units might be different), so I bought an inexpensive 60 amp A/C unit type cut-off switch box with a pull out switch. Just mount it near the heater on the wall and run your 6 gauge wire to it from your breaker panel.
I just wish they had included adapters so that you can plumb it to 3/4" piping, so you'll have to buy your own if you wish to connect it to your existing 3/4" pipe. I had trouble using pipe dope (maybe it was too old or the wrong kind?), so I switched to Teflon tape (5 layers) on each fitting and that did the trick.
Love the easy to turn dial, press to turn on/off feature and easy to read digital display which comes on when hot water is called for.
Now, we'll see how long it lasts before some type of failure...
