My water has been checked for iron and it was normal and the hot water outlet pipe looks fine as I installed both lines at the same time when I put in the heater.

Electrolisis. You may need to install a sacrificial zinc annode.

Some of the answers are getting close, yet everyone is beating around the bush.
Ok, lets all say it together now people....... Dielectric Union!
Everyone always asks, why is all this complicated plumbing necessary?
Well your situation is the living proof why it is necessary.
If you recall from high school chemistry, two dissimilar (different) metals, when placed in an acidic solution, will create a battery. And one metal will usually erode away as the chemical reaction progresses. The other metal may have a buildup of new material, which may be a chemical combination of the eroded metal and the acid. Since virtually all domestic water is slightly acidic or slightly basic, this electro-galvanic action can occur in any metal plumbing system.
When copper and steel pipes are connected together directly, the "battery" has a path for electrical current to flow. (This current is tiny, and the voltage is not a safety hazard.)
If the current cannot flow, because there is no electrical connection (interrupted by the plastic insulators) then the "battery" never discharges. In theory there will always be a small voltage between the different metals. The metals do not erode.

In your question you do not say wheather it is electric or not.if it is it is possible that one of the elements is damaged and the electric current is flowing through the water to a ground at some point. when this occours it will often take metal ions with it. usualy the anode rod will donate these Ions and pro0tect plumbing and tank from deterioration. the location of the hole was the easiest spot for the electrolysis to take place. be sure the electrical ground on the water heater is properly fastned and check your elements.
if it is a gas water heater check to see that the ground for the circut box attatches at one location only and that someone didn't try to save money by useing diferent spots on the plumbing as a ground.
if you used "black" iron pipe to do plumbing you have discovered why for water galvanized pipe should be used.

It really depends on the style and age of your water heater for the most part it will not over heat. The water in the tank will reach the temperature you have it set to and stop heating at the point. It will only turn back on as the water lowers in tempter. The only thing is since you do not have water going into the tank once the water in it is used up you will be out of hot water, until you turn it back on of course. Depending on the heater it may take a while to fill back up and reach desired temperature once you to open the valve again.

the reason i would suspect this is a mineral deposit in the line is restricting the flow of water INTO the waterheater. this being the case you'll find abit of deposit in the heater itself (instead of the outpipe) it settled at the bottom. the slower the water the quicker it rusts. in general steel rusts though most people use copper anymore because of this (it will still pinhole over time but alot longer) hope that helps.

Electrolisys.
ed has it 1/2 right.. the 2 metals are acting against each other... should have been the galv. hot/cold stubs(blue/pink plastic insides) or brass connections from the tank to the house lines. everything else might make it the life of the tank or not. the brass WILL last

Electrolisys.
Make sure you ground both sides of the replacement piping. It is the code anyway.
Use copper next time.

It's suppose to be iron water pipe and, it's most likely from corrosion from calcification.
