I just installed a new electric hot water heater and everything seemed to be running smoothly... the tank filled up fine and was heating the water, until I went to have a quick shower the next day and there was no hot water pressure. The cold pressure is perfect, just no hot. This is not just in the shower this is through out the entire house. Any idea's or suggestions would be fantastic!

Thanks in advance!

Something is plugged up. You might have to disassemble the pipes and find the problem. Something is somewhere it does not belong.
