Why don't I have enough hot water?
There are a number of reasons why this can happen.
Here are some of the most common.
Sediment or rust in the tank. Water contains minerals, even when treated from a municipal water source. The higher the concentration of the minerals, the "harder" the water is said to be. When hard water sits in a hot water tank, these minerals sink to the bottom and collect. Since most hot water heating elements are on the bottom, these minerals can coat or even partially cover the heating element, reducing the temperature of the water. Rust can also gather in a hot water tank and increase with age, causing the same issues.
A faulty thermostat. If the thermostat on your water heater is malfunctioning, it may tell the appliance that the water is at the proper temperature when it isn't. If your hot water heater is ten years older or more, this is a possibility.
A bad dip tube. The dip tube deposits fresh water into the hot water heater at the bottom near the heating element. Since heat rises, hot water can be accessible at the top of the tank while the water warms from the bottom. If the dip tube is damaged, it could be dropping fresh water near the top of the tank, which would lower the temperature of the water coming out of the hot water faucet.
Wrong-sized water heater. If you buy a new and larger appliance that uses hot water or you increase the number of people in your home, your demand for hot water could exceed the available supply. Think about the demand you are placing on the water heater. Has it increased without increasing the water heater itself?
There is too much demand at one time. Even the best water heater can't keep up with simultaneous showers, dishwashers, and clothes washers. Look at the time frame in which you are demanding hot water from the system and make necessary adjustments.
The Geiler Company offers a full line of tank-based and tankless water heaters, along with the experience and expertise to determine your hot water needs for now and in the future. We can also professionally install your new water heater so you know the job has been done right.
