Gas river stove making a bubbling pandemonium? I have a gas wet heater that is to say 10 years...

I have a gas wet heater that is to say 10 years old and when the dampen is running there is a loud clatter that is similar to air bubbling contained by the middle of the tank. What are the possibilities cause this sound?
Answers:    Wow, moderately a variety of WRONG answers. Only one is correct, it's a build up of lime, calcium sediment within the bottom of the tank. Over the years, this stuff builds up surrounded by the bottom of the tank and when the gas burner hits the bottom of the reservoir and heats it up, it make the small pieces of lime actually explode similar to popcorn, only underwater. These explosions don't really hurt anything, but they can be annoying if you can hear them from the living nouns of your home. Also, if it builds up enough, it cuts down on the available river to be heated and can make a shower shorter than it should be. It may be time for a unknown heater. Unfortunately, there's no influential way to drain or verbs this stuff out of a gas unit, excluding buying a self clean model. They're more expensive initially, but they'll extend the adjectives life several years.
