Also to know is, how can I make my hot water last longer?

Turn up the thermostat on the hot water heater. One of the easiest ways to make a hot shower last longer is by using less hot water while it's at a higher temperature. To do this, turn up the temperature on the thermostat that's attached to the hot water heater tank.

Also Know, how long should my hot water last? As a general rule, a tank style water heater will last, on average, 8 to 12 years. If your water heater is pushing the 10-year mark, there's a good chance it's time to replace the unit, and you may want to consider a tankless model.

Beside this, why does my hot water only last 5 minutes?

The most common reason for a dip tube going “bad” is because it's disintegrated away (or has started to). And when this happens, cold water no longer gets pushed down to the bottom. Instead, it mixes with the hot water at the top of the tank. Which means, your hot water supply quickly turns lukewarm/cold.

How long does it take for a 50 gallon water heater to run out of hot water?

So, a fully heated, 50-gallon tank will deliver roughly 33 gallons of hot water at any given time. The average shower uses 2 gallons of water per minute, so that same 50-gallon tank is good for a little less than 17 minutes of hot water.
