I have an oil burning hot water heater with a capacity of 30 gallons. My problem is that I can't take two showers in a row without running out of hat water. I replaced the shower head to a 2.5 gallon/minute head but that didn't help. I also tried turning the water temp on the aquastat to high. The water starts out plenty hot enough but just won't last. Could the water pressure entering the water heater be causing this problem? I don't know what else to try.

Thanks,
Tillio
