Why Do I Keep Running Out of Hot Water from My water heater? Proven Fixes
There is nothing more irritating than entering the shower and feeling how hot water turns cold in an instant. If you keep having problems with lack of hot water from your water heater, it means something goes wrong. In some cases, it could be a simple problem, but there are also situations when it requires professional intervention.
Fortunately, most hot water problems can be solved. You can learn about their causes and then solve the problem on your own.
The most frequent reasons why your water heater doesn't work properly
1. Sediment Build-Up
One of the main factors why people have problems with hot water is sediment build-up. The reason is that there is always something in your water and it settles in the bottom of your tank.
As a consequence, the water heater works much harder in order to provide the required temperature of water. And in the end, the layer of sediment works like a thermal insulator. So, much less heat goes to the water.
Symptoms of Sediment Buildup
- Shorter lasting time for the hot water supply.
- Popping sounds coming from the tank.
- Increased power bills.
- Increased heating time.
Remedies
Draining the tank once or twice yearly will help get rid of any sediment present. Nonetheless, professional cleaning will be a safer choice in case of thick sedimentation.
2. Defective Heating Element
In case of electric water heaters, it may be due to defective heating elements. Electric water heaters usually contain two heating elements, and if one of them fails, the heater won’t heat sufficient hot water.
Consequently, you’ll notice your showers go cold very quickly.
Symptoms
- Lukewarm water.
- Fast depletion of hot water.
- Long heating times.
A qualified plumber will conduct tests on the heating elements and replace the damaged one where necessary. Luckily, the repairs are quite easy to carry out.
3. Thermostat Issues
The thermostat regulates the temperature of your water heater. If the setting is low or if it stops functioning well, the water may never reach the right temperature.
Sometimes the thermostat will only need adjusting, but if the thermostat stops functioning well, then it may need replacing.
Look Out for These Signs
If your thermostat is not working properly, you may notice these signs:
- First, the water temperature keeps changing.
- Also, the water does not get hot enough.
- In addition, you suddenly run out of hot water.
Therefore, it is a good idea to keep your water heater thermostat set to 120°F. This temperature provides enough hot water for everyday use while also helping reduce the risk of burns.
4. Inappropriate Tank Size
Sometimes there is nothing wrong with your water heater; instead, you just might have a too-small tank for your family.
For instance, when many family members are taking showers at once, and the dishwasher and washing machine are also in use, the tank could drain before having time to refill.
A Larger Tank Is Needed In Case:
- You have expanded your family.
- You got an additional bathroom.
- Many devices operate simultaneously using hot water.
- Hot water tends to run out in the morning.
For many homes, increasing the size of the tank or choosing a tankless water heater would be a better long-term choice.
DIY vs Professional Maintenance
A few maintenance activities can be done by the homeowner, but most issues include electric components, gas components, or high pressure in the plumbing system. Thus, repair work must be done carefully.
DIY Tasks
- Set the temperature properly.
- Search for any apparent leaks.
- Clean the tank when advised by the manufacturer.
- Inspect the surroundings of the appliance.
Contact a Professional If:
- If your water heater is leaking, call a plumber as soon as possible.
- Also, if you hear loud banging or popping noises, your water heater may need professional attention.
- In addition, a faulty heating element should be replaced by an experienced technician.
- Likewise, if the pilot light will not stay lit, it is best to have it inspected.
- Finally, if you keep running out of hot water, a professional can find and fix the underlying problem.
The water heater is more than 10 years old.

The most common causes include sediment buildup, faulty heating elements, thermostat issues, or a water heater that is too small for your household.
