Hi,
I have a problem with my hot water heater. It is a two year old fifty
gallon unit. When I am the first person to use water in the house and
I take a shower I will start to run out of water within about fifteen
minutes. If the next person to shower waits about an hour there is
enough hot water to shower for at least thirty minutes. There only
seems to be a problem for the first shower in the morning. I replaced
the thermostat and that didn't fix the problem. Any ideas?

Thanks,
Jim
