What Is A Tankless Water Heater Electric

This allows you a constant supply of hot water.

What is a tankless water heater electric. In contrast storage water heaters last 10 15 years. Just as with gas powered models electric systems will save lots of money on your energy bills and give you constant hot water on demand without the limitations of a tank. Although tankless water heaters heat water on demand they do have output limits on their flow rate. So regardless of the type of tankless water heater you have you ll be out of hot water in the event of a power outage.

A tankless water heater is a marvel of engineering. Instead they heat water as it passes through the unit using a heat exchanger to rapidly bring it. Tankless water heaters can be powered by gas or electricity but even gas powered tankless water heaters rely on an electric control panel to operate the system. Tankless water heaters can avoid the standby heat losses associated with storage water heaters.

A tankless water heater is a heating element either gas or electric that connects directly to the home s water pipes. Tankless water heaters that run on electricity are the most affordable option for homeowners looking to retrofit their system. But from the moment you open a hot water faucet something remarkable happens. It is common for households to decrease their water heating energy costs by 15 or more just by making the switch.

When a hot water tap is turned on water flows through the element and is sent to its destination. Electric heating elements provide a slower flow rate than gas powered models. However although gas fired tankless water heaters tend to have higher flow rates than electric ones they can waste energy if they have a constantly burning pilot light. When you turn on the hot water the cold water travels through a pipe and into the tankless water heater unit where it is heated by a gas burner or an electric element.

To the untrained eye it s just a gray box that hangs on the wall. Tankless electric water heaters are extremely efficient using a minimum amount of energy to produce the maximum amount of hot water.
