Are you saying that nothing but air comes out of a hot water faucet or that you don't have any hot water at all? Why was the tank drained and refilled in the first place? Did you have hot water before the tan was drained?
Please explain with more details. Cheers, Tom

Make sure you open incoming cold water to the heater...
