You are right.
But everyone would have different adjustments to make.
If your house is kept at 72 and you keep your tank at 72.. it probably rarely runs.. but if your house is 68 and your tank is 80....
I figured it was easier for everyone to make their own adjustments using the number of hours per day.
I would guess, though, that most heaters run around 30-50 percent of the time.
And chillers.. I would have no idea.
But it makes for a nice rough estimate.
Now I just have to multiply by 5 tanks~
