I understand that you are having a problem with your hot-water tank not producing any amount of hot-water. I would suggest that you turn off the cold water supply to your hot water tank and drain the tank and see how much water comes out of it.
Flush the tank:
1. Turn off the cold water supply
2. Hook a water hose to the boiler valve (spicket on the bottom of the tank) and turn on the valve
3. Turn on the cold water inlet line and let it run for about 15 minutes or until you get good pressure coming out.
Check the Elements:
1. Turn off the power to the hot-water tank
2. Remove the service panels
3. Remove one wire from the element and use a multi-meter to check continuity
4. If no continuity replace one or both elements
If you do all of this and still have a problem repost to this thread and we will check your thermostats to make sure they are working properly.
At fifteen years of age it would be less cost over time and labor to replace the whole tank. How efficient is your old one and being it runs hot all the time you could have a tank that will not last very long anyway. Mine sprung a leak at 18 years and made a big mess.
If it's gas the control usually is at the bottom of the tank where the gas line comes in.
If it's electric there should be a little trap door either at the top or bottom and the heat control is behind that door. The door is usually held in place with a screw There is a little dial with numbers you can turn up or down. There are electrical wires that you should not touch as well.

If you have some hot water from dual-element water heater, then that tells us: Water heater is 240Volt. Upper element is working. If upper element is not working, then heater has NO hot water. Reset button is not tripped. Electricity and breaker to water heater are delivering 240Volts to heater.
