Also known as on-demand water heaters, electric tankless water heaters are compact and can easily be installed under a sink or in a closet. Unlike gas water heaters, electric water heaters don’t burn fuel or require an oxygen supply. As a result, they can be installed inside any unventilated space. They also work on a number of different voltages, including 120, 208, 230 and 277.
How Does An Electric Water Heater Work?
The heating of water in an electric water heater is done by electric elements. Depending on the design of the tank, most tankless units have one or two elements. These elements have elongated shapes and are designed to be immersed in water. When the hot water tap is turned on, hot water immediately exists the top of the tank. This hot water travels through a pipe until it reaches the faucet. At the same time, new cold water fills the bottom of the tank through a tube pipe.
The elements of an electric water heater are controlled by lower and upper thermostats. Each element is connected to a thermostat. Most residential electric water heater thermostats can be manually set to temperatures between 90 and 150 degrees. For safety, electric water heaters have a reset button that will trip when temperatures exceed the set temperature.
The Benefits of an Electric Water Heater
- Safety: When compared to gas water heaters, electric water heaters are safer. The chances of an explosion from a gas leak are much higher than getting an electrical shock from any faulty wiring in an electric unit.
- Installation of Timers: With an electric water heater, you can easily install a timer to cut off power to the tank at set times. If you’re on time-metered billing, it’s the ideal way to limit power consumption.
- Installation Costs: The cost to install an electric water heater is much less than the installation cost of a gas water heater. With a gas water heat, PVC tubing must be installed to vent the exhaust through a flu. With an electric water heater, you just need to have bare wiring or a special outlet installed.
- Space Requirements: Typically, gas water heaters require anywhere from six to 18 feet of ventilation around the sides and top. This means that you can’t just install the unit in a crawlspace or small closet. With electric water heaters, they can be installed in small spaces without any fear of a gas buildup.
