I have my hot water tank set to medium. I have not change the
setting, but it seams we are getting less and less hot water every day.
We are to the point where I don't have enough to fill my tub for a
hot bath. I think the tank is about 8 years old give or take a year.
Any idea?

When I had that problem, it turned out that a hot water line had ruptured
under the slab and the water heater finally couldn't keep up with the water
lost.
