AS water heaters age, they corrode and also incur mineral deposits and sediment at the bottom of the tank. This sediment is what causes the popping noises when the heater turns on. It is mini explosions inside the tank. Having yearly maintenance on the water heaters helps to prolong your heaters from having this issue by flushing out the sediment buildup and replacing the sacrificial anode rods when needed.
The water heater is most likely popping because of lime or seditment buildup in the tank. Depending on the age of the water heater, it may still have some service life yet, but flushing of the water heater may be required. I'm currently going through this myself and a quick internet search of "water heater flush" gave a lot of insight. Hope this helps.

However, some home advice experts recommend a second water heater. By adding an upstairs water heater, home owners decrease water and power usuage. They don't use as much water because it is warm on the spot.

It depends on if it's a gas water heater or electric. I don't think electric makes any noise, but a gas water heater, you'll the gas ignite, and hear the rushing gas from the burner.

The factory installs a restrictor in the heater hose fitting. It's made to slow the water flow up so you don't here the noise your hearing. It has rusted away.
