About Rheem Tankless Water

The Rheem Water Heaters are one of the most popular options on the market. It offers energy-efficient models that allow you to save money and reduce your carbon footprint by cutting down on wasted energy usage from a traditional water heater.

This product has a patented technology called “microprocessor control.” Rheem tankless gas models automatically adjust the amount of energy required to heat the water you need. This modulated technology increases efficiency and reduces energy consumption. This means that it can automatically adjust the amount of heat needed for the water in your home or office, so there’s no need to constantly adjust the temperature setting for the water.

You can read a detailed comparison of the Rheem Water heater vs the AO smith water heaters here.

It also has a “smart” element that allows it to detect when there is no more hot water left and turn off automatically, preventing waste and saving you money.
