How to make the hot water last longer?

My house is not too too old, but not new. When I move it, i was nine, the owner son just graduate from university. The owner build the house. So that’s about how old is the house.
Everytime I take a shower, it’s like a race, I have to do it as fast as possible before the hot water runs out. A handy man had come over, and he said and switch the temperature of the hot water hotter (he did it at the hot water production machine located at the laundry room), that’s all he can do. But switching the hot water temperature hotter doesn’t help make hot water last longer.
I thought it was just me taking shower too long, but I ask my friend, and she said she took very long and hot water still did not run out.

How to make hot water don’t run out so quickly? Especially in winter, it runs out more quickly.
It’s our house, we brought it, when I was 9, now i am about 30 ><!

I lost my job, changing water tank doesn’t seems possible.
well, I think the heat, water system, etc is technology of the 70s.
You are all welcome to view my other questions (about home and other topics), I’ll be glad to get more help. Thank you in advance ^^!

I assume you have an electric water heater.

If so I suspect one of the elements is burned out or one of the thermostats is bad. Electric water heaters have two thermostats and two heating elements. If one of the elements burns out or one of the thermostats quits working you don’t get enough hot water.

But first connect a hose to the outlet at the bottom of the tank and run water out of it for 10 minutes. See if clearing the sediment helps. Sometimes sediment keeps the bottom element from working right. If it doesn’t help then it is either a thermostat or heating element in which case you should call a service man and have it repaired.

  1. You should look at your hot water heater capacity. it could only be a 20 gallon whereas most people have a 50 to 100 gallon hot water heater.

  2. After some years waters become filled with various minerals instead of water. If you have a 30 gallon unit, and 20 gallons is sediment then you won’t have much hot water. The easiest thing to do is to replace it. If the home is rental then the owner should cover that expense. The easies way to make this happen is to install it yourself and take the heater off the rent.

  3. Sounds as if your hot water heater (electric) is too small for your house. You might need a bigger one.

  7. Get a water heater with a larger capacity. Or, one of the heating elements may need to be replaced: some electric water heaters have more than heating element. Of course you didn’t state whether it was electric or gas.

  8. Take cold showers and think of warm things.

  9. Can you wrap fiberglass insulation around the tank? It should help a bit.
