Water heaters are essential for modern living, providing the hot water needed for many tasks in our daily routine. Conventional units are among the most common types used in homes, consisting of key parts that work together to heat and store water efficiently. Basic knowledge of these components can help you take better care of your appliance, troubleshoot problems, and make informed decisions about water heater repair in Lombard, IL.
The Tank
This is the large cylindrical container that holds water until it is heated and ready for use. It is typically made of steel and lined with glass or similar material to resist corrosion. Tanks can come in various sizes, ranging from 20 to 80 gallons, to accommodate different household needs. Over time, the tank can experience wear, so routine inspections and water heater services are a must to detect signs of rust or leaks.
Heating Element or Burner
In electric water heaters, heating elements are responsible for warming the water inside the tank. These are usually located near the bottom and sometimes in the middle of the tank for even heating. Gas-powered units, on the other hand, use a burner located beneath the tank. This burner ignites gas to produce heat, which transfers to the water above.
Thermostat
The thermostat regulates the temperature of the water in the tank. During water heater installation, the thermostat is set to a specific temperature, usually between 120-140 degrees Fahrenheit. A malfunctioning thermostat can cause water to be too hot or not hot enough, leading to discomfort and potential safety hazards.
Dip Tube
The dip tube directs incoming cold water to the bottom of the tank. This simple yet vital part makes sure that hot water stays at the top of the tank for immediate use while cold water is heated below.
Anode Rod
The anode rod is a metal rod designed to prevent rust inside the tank by attracting corrosive elements in the water. It is typically made of aluminum, magnesium, or zinc and sacrifices itself to protect the tank lining. Regular inspection of the anode rod is necessary to avoid premature water heater replacement. This component must be switched for a new one every three to five years, or when more than a third of its original length has been depleted.
Pressure Relief Valve
This is an important safety feature that prevents the tank from over-pressurizing. If pressure or temperature inside the tank exceeds safe levels, the valve releases water to avoid potential damage or explosions. This component should be tested periodically to make sure it operates correctly.
Drain Valve
The drain valve is located near the bottom of the tank and allows homeowners to drain water from the unit. This is especially useful during routine maintenance, such as flushing sediment from the tank. Sediment buildup can reduce efficiency and shorten the lifespan of the water heater, so using the drain valve regularly helps maintain optimal performance.
Flue Pipe
In gas water heaters, the flue pipe vents combustion gases safely out of the home. It is typically located at the top of the tank and extends to an exterior vent. Proper ventilation is critical for safety, as it prevents harmful gases, like carbon monoxide, from accumulating indoors.
