M:-- Gas fired water heaters can accumulate large amounts of precipitated mineral debris at the bottom of the tank. This gravellike material acts like an isulating blanket between the water and the tank bottom. This accumulated mineral debris interferes with the passage of the heat energy from the main burner into the water. As this debris becomes deeper, steam is generated on the tank bottom and as the steam bubble emerges into the cooler water above the layer of debris, it collapses (implodes) back into water with a loud pop or bang. Some heaters really can get "Rockin and Rollin" at times and sounds like something alive and dangerous is living inside the heater. A lot of loud crunching noises punctuated with some mini-explosions can get on your nerves after awhile. There is little to fear about a sudden failure or flooding connected with this noise problem.
You could try cleaning the junk out of the bottom of the heater to reduce the noise to a manageable level, or replace the heater. A reduction in the fireing rate by a qualified Gas Technician will also help in the solution of this problem.....Happy New Year...Bud..
