I have seen many presentations on these. My take away is if it is inside the heated envelope of the home, you are paying 1) to heat the house and 2) to heat the water. Meaning, you are using a very inefficient means.
If the WH is OUTSIDE the envelope, then it should be reviewed and analyzed. And, probably makes sense.
I could be wrong, but sucking heat out of your home (that you already pay for) seems dumb.
