What’s Inside An Electric Water Heater? – Plumbing Basics

December 7, 2023

In American households, electric water heaters are an indispensable part of daily life, providing the comfort and convenience of hot water for showers, dishwashing, and various other tasks. These reliable appliances have evolved over the years to become energy-efficient and eco-friendly, meeting the demands of modern homeowners while reducing environmental impact. In this article, we will explore the key features and benefits of electric water heaters, highlighting their importance in American homes.

The inside of an electric water heater contains several key components that work together to heat and store hot water for domestic use. Let’s explore the internal structure and components of a typical electric water heater:

Tank: The tank is the main body of the water heater and is usually made of steel with a glass lining to prevent corrosion. It holds and stores the water, keeping it hot until needed. Tanks come in various sizes, typically ranging from 20 to 80 gallons or more, depending on the household’s hot water needs.

Tank

Thermostat and Heating Element: The thermostat is a temperature control device that monitors the water temperature inside the tank. It signals the heating elements to turn on or off as needed to maintain the preset temperature. Users can adjust the thermostat to set the desired water temperature.

Temperature and Pressure Relief Valve: This safety device is an essential component in case of excessive pressure or temperature buildup inside the tank. If the pressure or temperature exceeds safe levels, the valve opens to release hot water and pressure, preventing potential tank damage.

Cold Dip Tube and Anode Rod: It is where cold water enters the tank. The dip tube ensures that incoming cold water is directed to the bottom of the tank, allowing the hot water to stay at the top for use. An anode rod is a sacrificial metal rod that is suspended inside the tank to help prevent corrosion. It attracts corrosive elements in the water and protects the steel tank from rusting.

Metal drain Valve: Many electric water heaters have a drain valve near the bottom of the tank. This valve allows users to periodically drain and remove sediment buildup in the tank, which can affect the heater’s efficiency.

Electric water heaters have become an integral part of American households, offering energy efficiency, convenience, and environmental benefits. As technology continues to advance, these appliances will only become more efficient and eco-friendly. With their quick recovery times, low maintenance requirements, and compatibility with renewable energy sources, electric water heaters are a reliable and sustainable choice for American homes, ensuring a steady supply of hot water for daily needs while contributing to a greener future.

Bella is very knowledgeable about tankless water heaters. She determined that the heater that I purchased from Amazon was the wrong model. She went above and beyond the call of duty. She drove me in her car to the UPS store so I can return the heater and then drove me to the supplier store in San Jose (Pace Supply) so I can buy the correct one. She is very honest and showed me the wholesale price of the heater and used her coupon to get me the wholesale price. Umed, the technician, is an expert and did a great job installing the unit. He arrived on time, was very polite, and cleaned the area after his work was done. Bella and Umed put the customer first and provided an excellent service. I highly recommend United Plumbing because of Bella and Umed, their honesty, great service and expertise.

Technician Beck came on thanksgiving day, working from 3pm till almost 9pm, to replace a new water heater. In the middle of the installment, he even had to go back to his office and pick up new parts. It was very difficult to set up the tubes at my place since the space for the tubes/water heater was limited. Technician was very patient and friendly the whole time. The pipes after Beck’s work are better designed. I am very grateful they are willing to come on a big holiday like thanksgiving, getting the challenging work done without any complaints. Otherwise it would be a cold shower thanksgiving for us. Highly recommend.

United was quick to do an inspection and quote to replace our 20 year old tank water heater for a tankless and was able to start the job the same day. Professional and great service and the price was the lowest I received out of 3 or 4. Highly recommend!

Yuri was great! Yuri came to inspect the pipes that were hearing while the water is running but unfortunately we weren’t able to hear anything at the time of the inspection. Yuri was able to install a new faucet in my kids bathroom. If you are looking for a plumbing company use United Plumbing, from the office to the field the service was great! I will definitely use Yuri and United plumbing again in the future.
