How Does an Electric Tankless Water Heater Work?

Electric tankless water heaters, also known as demand-type or instantaneous water heaters, provide hot water only as it is needed. They don’t produce the standby energy losses associated with storage water heaters, which can save money. Here you’ll find basic information about how they work.

Electric tankless water heaters heat water instantaneously without the use of a storage tank.

When a hot water faucet is turned on, cold water flows through a heat exchanger in the unit, and either a natural gas burner or an electric element heats the water. As a result, electric tankless water heaters deliver a constant supply of hot water. You don’t need to wait for a storage tank to fill up with enough hot water. However, a tankless water heater’s output limits the flow rate.

Typically, electric tankless water heaters provide hot water at a rate of 7.6–15.2 liters per minute. Gas-fired tankless water heaters produce higher flow rates than electric ones. Sometimes, however, even the largest, gas-fired model cannot supply enough hot water for simultaneous, multiple uses in large households. For example, taking a shower and running the dishwasher at the same time can stretch a tankless water heater to its limit. To overcome this problem, you can install two or more electric tankless water heaters.

The panel adjusts the electric valve, the mixing valve, and the water flow to achieve the desired temperature setting.

Most tankless water heaters have a front-facing panel that allows the user to control its settings. This panel enables homeowners to adjust the gas to exactly how much they’d like to use. For electric tankless water heaters, panels can also control the amount of electricity. This allows homeowners better to manage their water, electric, or gas bill.

The electric tankless water heater panel also allows personalized settings, such as the mixing value and the amount of water flow. When installing a tankless water heater, homeowners should discuss with their plumber what their preferences are and ask them to set the water heater accordingly. Homeowners should avoid drastically changing their settings if they do not have a precise reason for the shift.
