This is a type of gas water heater
Question: Fellow blogger, Funny About Money, asked, does a gas water heater ever need to be drained?
Answer: Yes, it is always good to drain a gas water heater once every few years, just so sediment doesn’t build up in the tank.Tanks are made of steel and along with water, sediment corrodes steel.
If you have an electric water heater, then those need to be drained every year, otherwise the heating element literally dissolves.
How do you drain a gas water heater? First, shut the breaker off to the water heater and shut the house gas supply off. You then drain it by opening the valve at the bottom of the unit or releasing the safety valve on the upper side of the unit.
