Not getting enough Hot Water?

Is your bathtub not getting enough hot water for a luxurious soak? Do you run out of hot water during a routine shower? Running out of hot water is never any fun and can be caused by a few different issues. Read below to see what might be causing your hot water to run cold. You can also contact us 24/7/365 to speak with a water heater expert and let us help diagnose the problem. Water Heaters Only, Inc can help you determine if you need service for your water heater.  

Top Reasons for not enough hot water

  • On a gas water heater, the gas control valve (thermostat) could be broken.
  • The dip tube inside the water heater could be bad, causing a reduced flow of hot water through your pipes.
  • If you are new to the residence, the tank may be undersized for your needs. You may also have a tank that is smaller than at your previous home. 
  • If your water heater is 8+ years old or if you live in an area with hard water, your water heater could be full of sediment. This will reduce the amount of hot water a water heater can make.
  • You may have increased your water heater needs over time.
  • For an electric water heater, an electric element or thermostat could have burned out.


Firstly, as a water heater ages and nears the end of its useful life, it will produce less and less hot water. Most often this is caused by sediment building up inside the tank. Sediment build-up will decrease the amount of hot water your water heater can produce. As a result, the water heater can become noisy or make a loud rumbling sound. Sometimes you can flush sediment out of the water heater to fix the problem. Other times it cannot be flushed effectively and replacing the water heater may be the only solution. 

Malfunctioning Part

A malfunctioning part can also be the source of not having enough hot water. Over time a part can wear out and cause the water heater to malfunction. Most often, a bad gas control valve or a faulty element can easily be replaced to get your water heater working at top efficiency again. If the water heater is over 10 years old, it’s a good idea to think start to think about a replacement vs repair. Most water heaters have a life expectancy of 8-12 years.
