    A:  Hi Allen, the difference between the units is an internal pump in the RXP199iN, that will allow the unit to recirculate.

        Rinnai solid quality!
        I went with Rinnai for their reputation of solid quality, longevity, and savings. When speaking with installers and plumbers, Rinnai frequently comes up as most reliable and worry free! This unit is an absolute BEAST! Likely could have gone with something smaller, but whether small or big, installation cost was all the same and I didn’t want to have to upgrade later as my family grows. This unit is very quiet, barely noticeable. Can’t recommend it enough!

          Chose this model Rinnai because I wanted the highest GPM flow and a recirculating pump. Thermal cross over valve included! Shipped double-boxed in extra heavy duty cardboard. Does not include Wi-Fi module, but can be found online.

          Love the recirculation feature! Well worth the additional expense.

          This RXP199iN is very quiet. Connections were straight forward. Works well with my existing concentric vent system. This unit comes with a thermal expansion valve and an internal recirculation pump. My hot water gets to the source fixture much faster. You can change the stock maximum setting of 120 degrees Fahrenheit to a maximum 140 degrees Fahrenheit by changing a program setting. I personally have mine set to 125. I would recommend this unit!

          This is our first Rinnai tankless water heater so can't give a solid review other than the recirculating feature is great (make sure you install the thermal bypass valve). This alone is a game-changer since our last unit didn't have it. I'm looking forward to seeing the longevity of this unit though. Hope it outlasts our last one. We bought this unit to replace a Rheem tankless unit that barely made it to the 10 year mark. I've heard tankless units are supposed to last double the life of a tank, which can be up to 10 years. So expecting this unit to at least make it 15 years, and not, disappointed me. Then, when my plumber called their support for additional assistance, he was told, "Sorry, you're out of warranty, go check out YouTube." Uh, yeah... not good.
