Energy Efficient Tankless Water Heater Products — Saves Money and the Environment

Powered by a 90-year legacy of achieving higher standards in water heating, Rheem is committed to providing energy-saving technologies to our customers. Tankless water heater technology is a huge advance in our industry, and we have embraced it without replacing the tank-type water heaters that have worked so well for so many years.

Heating water can account for up to 30% of a home’s energy budget, which represents an opportunity for homeowners to save money. The reduction in the amount of energy consumed also represents a savings to the amount of greenhouse gas emissions from the energy expense. Consumer reporting agencies cite that tankless water heaters are 22 percent more energy efficient than the gas-fired tank-type storage water heaters.

The Rinnai tankless hot water heater is a state-of-the art, energy -efficient water heating system that uses a gas powered heat exchanger to heat water on demand. Compact in size our innovative tankless technology heats water only as needed when water flow is detected, resulting in endless hot water. And unlike traditional tank systems, the Rinnai system can deliver hot water to multiple water sources simultaneously at a constant user-set temperature.
