So I measured the temp. differences of the water heater again and I got pretty much the same results. The temperature of the tank definitely heated up, however, I never actually heard the tank getting up and running to heat the new water, but then again I never have and we still have hot water all the time, so it must be heating, just quietly. It's a gas heater.
The tank temp. heated up about 5* from 70 to 75*, but I can't tell if that is attributed to heat loss or the outside environment heating up. Any ideas? Is it worth putting the blanket on or will a 5* change not show any real ROI?
