One can heat the water up to 84 degrees, and then a 6
degree drop down to 78 would be not a problem. Or 82
degrees and drop 6 degrees down to 76, still not a
problem. Even dropping down to 72 is not too bad.

What temperature drops have you observed and how fast ?

This was years ago, but, IIRC, the outside temperature was in the single
digits. The drop of temperature in the house went from the low 70s to
the low 50s or high 40s in the space of 45 minutes. My tank was either
100 gallons or 125 (I upgraded during that period). The temperature drop
was about 6 degrees, maybe more.
