The new Noritz America RPK-EXT External Pump Kit gives users the time, water, and energy-saving benefits of hot water recirculation on an even broader array of residential tankless water heaters. Previously available only as a fully-integrated circulator in the NRCP line of condensing tankless water heaters, the new RPK-EXT kit can now serve as a separate, add-on component to 26 additional Noritz residential models.

The RPK-EXT delivers hot water to a faucet, shower or appliance in seconds, eliminating the usual water and energy-wasting wait. Using a sensor to monitor the hot water line, the circulator automatically shuts off once the preset temperature is reached. Using a dedicated return line, the RPK-EXT also sends water that has been sitting in the hot water line back to the tankless water heater for reheating and recirculation.
