Why do we run out of hot water so quickly?

Home » Why do we run out of hot water so quickly?

Imagine you are in the middle of a shower and suddenly you are standing underneath a stream of cold water. Worse yet, your hair is full of shampoo! What is causing your sudden less than relaxing shower? Why do you keep running out of hot water?

Sediment Buildup

Water that runs into houses contain minerals and sediment:

  • Calcium
  • Magnesium
  • Manganese
  • Molybdenum
  • Copper
  • Iron
  • Zinc

All of these minerals, whether good or bad, dissolve and settle at the bottom of your water heater tank. A water heater that has not been flushed for years will have a significant buildup which decreases the capacity of the tank to hold hot water. Warning signs that there is too much buildup might be:

  • Sediment coming out with your hot water
  • Knocking, popping or cracking sounds coming from the water heater
  • Hissing or leaking from the water heater valve

Bad Lower Heating Element

Electric water heaters have two heating elements, one at the bottom and one at the top. The one at the bottom heats the water that comes in, which naturally rises, while the one at the top keeps the temperature consistent. When the lower heating element is damaged you will notice a considerable drop in the amount of hot water before it runs out.

Broken Dip Tube

Cold water enters the unit from the top and travels to the bottom of the tank via the dip tube. If the dip tube breaks, the cold water will stay at the top and mix with the water that has already been heated and is sitting at the top.

Thermostat

Most water heaters have a thermostat. It is possible that it just need to be reset.
