What can cause a water heater to suddenly start running out of hot water more quickly?


I seem to be asking you all sorts of questions! My water heater is old (of course) and has suddenly started over-heating the water? The water comes out extremely hot at first and then about 10 minutes into a shower, or dishes, the hot water runs out. This is unusual, it usually lasted about 30-45 minutes before running out. I'm assuming it's probably something with the thermostat, but thought I'd ask the expert! (Yes I know it's dusty).

    Another problem may be the bottom thermostat malfunctioning. This means only the top element is getting power. A multimeter will tell you if either element or thermostat is at fault if you know someone who can read one for you.

    It could be hard water as well. We have a well and no water softener! Thank you, I will check this first.
