How Does an Electric Water Heater Work?

Are Electric Water Heaters Tankless?

Electric water heaters present vital appliances of the household for many working families in America. As such, it’s important to dive into some specifics about water heaters, including how they work and what their capacity is. Many homeowners who are considering a switch to electric water heaters may find themselves asking whether or not these water heaters are tankless. It’s important to note that tankless water heaters are available in both electric and gas-fired versions. It is important to note that a tankless model water heater will require an oversized electric service, which can be expensive to install from the outset.

Do Electric Water Heaters Need to Be Vented?

One of the most interesting aspects of electric water heaters is the fact that they do not need to be vented. This is in contrast to natural gas water heaters, which need venting. This is also true of both the tank and tankless versions of gas and propane water heaters. For homeowners, needing an extra venting area for the water heater can be a deciding factor in whether they choose gas or electric.

When to Replace Electric Water Heater

As a homeowner spends time and energy in their household, it’s important to maintain and replace appliances as necessary. If your electric tank water heater is more than a decade or two old, it’s important to sincerely consider a replacement. A brand-new electric water heater will provide increased efficiency and potentially lower monthly bills depending on the model. Another way to determine if your household would benefit from a new water heater is to check your water heater’s warranty. This warranty will help you determine the most accurate timelines.

If you are wondering about which electric water heater to choose, it’s likely best to consult with an expert in the industry. There are many electric water heaters on the market. Popular water heater models include the following:

  • The Rheem Marathon Electric Heater
  • The Ecosmart ECO 27 Electric Tankless Water Heater
  • The Bradford White Hydrojet Electric Water Heater
  • The Stiebel Eltron Accelera E Hybrid Heat Pump Water Heater

This sampling of water heater models presents just a fraction of the available water heaters on the market. A water heater repair specialist will have informed opinions on what will benefit your household due to years of experience and training.

When to Reset the Water Heater

If the temperature of the water heater becomes too high and could be dangerous for the users of the water heater, an emergency limit switch will be automatically tripped. This temperature limit is typically one hundred and eighty degrees. After the water heater has been tripped, it can be reset when it is ready for use once more. Now, somewhere on your electric water heater, you will find a reset button which can usually be determined because it is red and located near the thermostat. However, it may also be hidden behind a removable metal panel on the unit. Once the button is properly located, push and release it to reset your electric water heater.

What is Electric Immersion Heater?

An interesting electric heater variation is the electric immersion heater, which is usually inserted directly into a pipe, tank, or vessel to heat process liquids or gases. Because the heat is created by electricity, practically all of the energy is used by the product being heated. It works similarly to a kettle, in that is uses electric resistance heaters to heat the water around it. It will be connected to the electric mains by means of a cable.

Where is Electric Water Heater Thermostat

If you’re wondering where the electric water heater thermostat is, you may be surprised to find that there are two thermostats on electric tank heaters. One is at the top of the apparatus and the other is at the bottom of the tank. Most tankless electric water heaters will have a display that has a temperature readout and a set of controls that can adjust the temperature.

Electric Water Heater to Tankless

Depending on the benefits perceived by the change from the tank to tankless, the switch can be extremely beneficial for homeowners. Tankless water heaters are quickly becoming the standard for new home construction. This is due to the fact that tankless water heaters are so energy efficient! It’s important to also understand taht newer tank water heaters tend to have a UEF (Uniform Energy Factor) rating of .7 compared to a standard tankless water heater with a rating of .94. This is a significant difference in energy efficiency and should be considered when it comes to the long term use of these appliances.
