What Is A Tankless Water Heater Electric

Instead they heat water as it passes through the unit using a heat exchanger to rapidly bring it.

What is a tankless water heater electric.

Although tankless water heaters heat water on demand they do have output limits on their flow rate. Tankless systems heat your water on demand using gas or electric coils. When a hot water tap is turned on water flows through the element and is sent to its destination. To the untrained eye it s just a gray box that hangs on the wall.

Tankless water heaters take up much less space than storage water heaters as they heat the water directly. 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. In contrast storage water heaters last 10 15 years. Tankless water heaters that run on electricity are the most affordable option for homeowners looking to retrofit their system.

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. 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. Tankless water heaters can avoid the standby heat losses associated with storage water heaters. 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.

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. A tankless water heater is a heating element either gas or electric that connects directly to the home s water pipes. This allows you a constant supply of hot water. Electric heating elements provide a slower flow rate than gas powered models.

It is common for households to decrease their water heating energy costs by 15 or more just by making the switch. As their name implies tankless or on demand water heaters don t store water in a tank.
