The Rheem RTEX-24 24kW 240V Electric Tankless Water Heater is a powerful machine that heats up water in a matter of seconds to provide hot water to the home, from showers to sinks and more. This heater is corded but can be mounted on the wall to take up less space, and requires 240 volts to provide 24 kW output to the machine. The metal alloy will last for years and is nearly 100% energy efficient, making it a great, economical switch for the home.

Customers say this appliance heats up water for long, hot showers in seconds, and provides hot water to the home for hours. They say it is trustworthy, does not take up much space in a basement, and and they like how it self-regulates its own temperature. If users want it hotter or cooler, they can change the digital thermometer themselves. However, this machine works on its own and is more energy efficient than tanked ones. Others say it works very well even faster than others.

Some say they had issues with installation, saying they highly recommend having it done professionally from a plumber or electrician. However, instructions provided claim users can do it themselves.
