Should the top and bottom water heater thermostats be set to the same temperature?
I did a quick google search and saw all kinds of differing opinions. for instance, this guy seems like he knows what he's doing:
and he said the top thermostat should be set to a higher temperature than the low one, but other places I've read said they should be at the same temperature.
my water heater's old, if that makes a difference. I didn't see a date, but the energy sticker had some reference to 1994. sorry I don't have more info; the thing's wedged back in a tight closet and hard to get to.
