You said you let it run for an hour, can you hear it?
There is a bypass valve, that will NOT let any hot water through, in other words when you open your hot water facet, it will be cold..
If you water heater is actually heating the water, then it would be a bypass valve, usually located on the back side of the water heater, access is usually through a cabinet or drawer, mine I have to take the drawer out from under the stove, and the valve is right there.
I believe from what you are saying that the water heater is on.
While your in there checking the bypass valve, reach down and try to feel the water heater, it should be warm.
