Houston. Attic. There's probably not much energy being used to keep that water warm during the day for a good part of the year
. I wonder what the energy difference is using the free daytime heat to warm a tank of water vs. having to heat each drop of somewhat cooler house water?
Still may make sense, but I'd think the payback would be slower there...
