For another 80 bucks you can get 10 more gallons..
Since we are a low demand family, I'm voting for the 40 gal.. Comments?

Dang, this thing weights over 100 pounds! My back is already killing me..


Edit:
I noticed this unit has two 4500 watt elements (at 240vac), I wonder if you put these two elements in series,
4500/240=18.75 amps. 240/18.75=12.8 ohms x2=25.6 ohms. 240/25.6 =9.375A x 240=2.25 KW... (or 1.124 KW at 120vac)..?.

Using those elements at 1.124 kw puts 3835 BTUh into the tank..
Not much, but that's not bad, considering the A7 sends around 6500ish BTUh to the tank during normal operation.

I'm thinking that burning 1KW might be useful to keep the tank luke warm,
during those extra cold January days when the A7 is dropping the basement to 40F !!
This elements have 2 thermostats. They never work together. Check manual. I installed electric HWT with the same 2 elements 4.5 KW each. Here is how they wired :
