Hot Water When You Want It: The Comfort and Savings of Recirculation

August 13, 2025

It’s easier than ever to give homeowners an advanced, no-wait hot water solution with Rheem® IKONIC® Tankless Water Heaters with recirculation. SR-Series models are intelligently designed with a built-in recirculation pump and Wi-Fi, offering homeowners the ultimate hot water experience with convenience, control and water savings.

Innovative Rheem SR-Series recirculation technology quickly gets hot water to your fixture when and where you need it. In a water heating system, a recirculation pump circulates hot water from your water heater through your pipes and back. This means hot water is waiting at the fixture (like faucets, showers and appliances). Without recirculation, cold water sitting in the pipes will be wasted down the drain while you wait for hot water.

Recirculation Benefits Add Up

Time Savings No more waiting for hot water at faucets, showers, and appliances. SR-Series models are ideal for homes with long pipe runs or multiple stories. Did you know the average home wastes 26 hours per year waiting for hot water?

Dramatic Water Savings Homeowners can save up to 12,000 of gallons per year from being wasted down the drain waiting for hot water! That’s the equivalent of 3,000 loads of dishes!

Convenient Control Homeowners have the option to program the built-in recirculation pump to fit their household needs. SR-Series models with built-in Wi-Fi powered by EcoNet® technology can be controlled remotely using the EcoNet app on their mobile device or on-unit control panel.

Three Recirculation Modes:

  1. Timer Based (Performance or Energy Saver) – pump will cycle on every 15-30 minutes in Performance mode or every 30-60 minutes in Energy Saver mode
  2. Custom Schedule (Operates in Performance During Select Times) – homeowners can set specific times during the day for the pump to turn on
  3. On-Demand – homeowners can activate the unit by setting the pump to ON

The Ultimate Upgrade

Rheem’s IKONIC SR-Series tankless water heaters with built-in recirculation give you the ultimate upgrade for a continuous, no-wait hot water experience. In addition to saving water and time, these smart, super high efficiency models also significantly reduce energy use compared to a standard tank water heater and are backed by the industry’s most comprehensive warranty.
