We have no hot water throughout any hot water faucet.
The cold water is fine.
I can here the water heater on and warming water and if you open the valve on heater there is hot water. But, there is no water or preasure in faucets.

Have you done any pluming work in the house, and what do you mean by opening the valve on the heater? If you mean opening the water heater drain valve sure you would not get any hot water because the dip tube shoot cold water to the bottom of the tank,Thanks.
