Generally the year of manufacture for Rheem is 3rd and 4th digit of serial number. 06 is 2006, 92 is 1992 etc.
Older gas water heaters are better than new ones, and easier to keep repaired and maintained.

Regardless of age, the key factor is whether tank is rusted, or rusting.
Open drain valve and check if water is rusted.

Thermostat may be heating element hotter than normal causing a change in temperature causing the noise. You could try adjusting temp down a little on thermostat. It sounds like it's getting the water very hot and thermostat may not be working correctly.

Unfortunately, no... According to the Rheem website, the Rheem Fury model 22V50F1 has an energy factor of 0.58:

In order to qualify for the credit, the energy factor must be 0.82 or greater...
