How it Works

electric water heater

A. O. Smith electric tank water heaters heat water using one or two electric heating elements. When a hot water tap is opened, water pressure from the street pushes cold water into the system through a dip tube that delivers it toward the bottom of the tank. This pushes hot water from the top of the tank out to the hot water pipes for distribution of hot water throughout the home. Temperature sensors inside the tank signal the thermostat when to turn on the heating elements to add heat to the stored hot water. Each electric tank water heater includes a thermostat, a temperature and pressure relief valve, and a drain valve. All of these components are needed to monitor the hot water and ensure efficient, reliable, and safe operation. The thermostat cycles the heating elements to regulate the water temperature to the specified temperature set on the control.

Still Have Questions?

Depending on your needs, gas tank and electric tank water heaters each provide their own wide range of benefits. Gas water heaters are typically cheaper to operate than electric. However, they cost more upfront and depend on the availability of a gas supply line and adequate venting at the installation location. There are a few different types of venting options that can be used for gas tank water heaters.

Electric tank water heaters are energy-efficient solutions for your home’s water heating needs. A. O. Smith’s electric tank water heaters have a UEF rating between .89 and 3.45, helping you save energy in your home. Although the recovery rate of electric water heaters is slower compared to gas water heaters, electric models can be less expensive to purchase and installation costs are generally lower.
While you might be able to install an electric tank water heater by yourself, A. O. Smith strongly recommends that you consult a local plumber or contractor to assist in the installation of your water heater. A local plumbing contractor can help ensure that the installation was done correctly, safely, and up to code so that there are no faults in the unit due to an installation error, which can lead to disruptions in hot water delivery or damage to your home.
Since electric water heaters don't burn fuel or generate exhaust fumes like gas water heaters, they don't need gas lines or ventilation, simplifying installation. Electric water heaters tend to be cheaper than gas water heaters of comparable sizes, potentially reducing your initial costs. An advantage of having a tank water heater is the large storage supply of hot water, making it available when you need it most.
There are many variables to consider when deciding what size of electric tank water heater to purchase. These include groundwater temperature, size of home, number of household members, number of bathtubs and/or showers, and hot water usage patterns. A. O. Smith offers a variety of models and sizes to suit your home and your family’s needs so that you never have to worry about running out of hot water. Consult A. O. Smith’s online XPERT™ Product Selector.
No. Electric water heaters draw their power from electricity. Since they don't depend on combustion to generate heat like a gas water heater, they don't create byproducts or require exterior ventilation.
