Natural gas tankless water heater with recirculation pump

Recirculation Benefits

Waiting for hot water can be frustrating, costly, and wasteful. Recirculating technology eliminates the wait, so hot water is always at the ready. Our technology permits this even if your home does not have a dedicated return line.

How Intelligent Recirculation™ Works

If your home does not have a dedicated return line, select Rinnai tankless water heaters can offer faster hot water without adding an additional cold return line. This technology allows for the simple installation of a thermal bypass valve at the fixture farthest away from the water heater. Once installed, the unit temporarily uses the cold water line for recirculation. 

About the Noritz NRCR92-DV-NG

Do you ever feel tired of waiting for hot water to show up and worry about wasting water down the drain as you wait for it to warm up? Noritz has a solution and is proud to introduce its all-new NRCR92-DV-NG natural gas water heater! This water heater is like no other. It comes equipped with an integrated recirculating pump that helps make hot water readily available every time you need it and prevents cold water from being wasted. This recirculation pump also allows for a ½” loop with a 200’ length (or 3/4” up to 500 feet) for radiant systems. This impressive distance is the longest in the industry and is very helpful especially for those who have bigger houses and wider spaces. This tankless water heater has three recirculation modes available: Recirculation Mode (with a dedicated return line); On-Demand Mode (requires the IHK-GB or IHK-RS); Crossover Mode (requires the CSV-BPK) which will allow more flexibility during operation.

And if you think this water heater with all its many features is too complicated to operate, think again. With the use of the NWC-ADAPTER (sold separately), this innovative water heater can be controlled wirelessly on your smart device. But even without the Mobile app, this innovative water heater almost runs itself with a default Learning Mode that helps you with scheduling. Isn’t that fantastic?

If you are concerned about efficiency, this heater features a 0.97 UEF rating which is one of the best energy factors in the tankless market today. This unit is equipped with a revolutionary burner (first in the industry) that reduces effective BTU output to less than 10 KBTU during summer when the incoming water temperature is high. This 73lb. hot water heater’s BTU rating can range from as low as 18K to 199,900 BTU per hour. It has an impressive maximum flow rate of 9.2 gallons per minute and can hold 0.85 gallon (or 3.2 L)  of water for even quicker hot water access.

One of the more amazing elements of this high-end Noritz NRCR92-DV-NG water heater are the high-quality heat exchangers that are made of serviceable stainless steel and are covered by a 15-year warranty; that’s how confident Noritz is when it comes to its durability! Noritz has been a leading innovator in the world of water heating for more than 60 years. Carrying modern, technologically advanced products like this NRCR water heater is one of the reasons why Noritz is a brand that you can count on.

Can you have tankless water heater with recirculating pump?

Rinnai tankless water heaters have built-in pumps with Smart-Circ™ Intelligent Recirculation™ that learns your schedule. No dedicated return line, no problem. A thermal by-pass valve added to the cold water line helps ensure recirculation is enabled, and your unit takes it from there.

Is a hot water recirculating pump worth it?

With the average national cost of water rising rapidly, a hot water recirculation pump could easily save you upwards of $50 each year. Since these pumps cost between $200 and $250 each, you could pay back the investment within a couple of years.
