If you were able to bleed the water heater and got water out of the "pop off"" valve, you obviously have water going in the tank. If you no water coming out, symptom, no water coming out out of the hot taps, you probably have a bad outlet valve, or turned the wrong way. That would be the valve at the top of the tank.
What to check: Turn the top valve the other way and test for water.
If no water, turn the bypass valve and test for water. I say do this to to check the integrity of the rest of the plumbing. Would be unlikely, but you could have a blockage in the line, after it leaves the water heater, before it goes to any of the taps.
Good luck, and let us know.
