Why Does My Hot Water Run Out So Fast?
Expecting a relaxing, warm shower only to have the water turn cold right when you’re midway through is frustrating. Finding yourself regularly running into this problem and asking yourself, “Why does my hot water run out so fast?” Several factors could result in your hot water not lasting long, from minor, DIY-able issues to larger problems requiring a licensed and insured plumber.
Common Reasons Your Hot Water Runs Out Quickly
- Sediment buildup in the tank: Over time, minerals in the water collect at the bottom of your water heater, reducing its capacity and making it seem like the water heater runs out of hot water fast.
- Faulty heating elements or thermostat: If these components malfunction, the water heater can’t heat water effectively, meaning your water heater runs out of hot water quickly.
- Small tank size: If your household uses a lot of hot water at once, your tank may simply be too small to meet demand.
- Broken dip tube: A dip tube directs cold water to the bottom of the tank to be heated. If it’s broken, incoming cold water mixes with hot water, cooling it down too quickly.
Solutions to Improve Hot Water Supply
What you can try:
- Flush your water heater annually to remove sediment buildup.
- Lower your hot water usage temporarily, such as staggering showers or washing clothes in cold water.
- Adjust the thermostat to ensure the water is heated to an optimal temperature (typically 120–140°F).
What will require a plumber:
- Have a plumber inspect and replace faulty heating elements, thermostats, or a broken dip tube.
- Upgrade to a larger tank or install a tankless water heater for on-demand hot water.
- Schedule regular maintenance to prevent future issues that make your hot water run out fast.
