## Description

Rinnai's super-high efficiency plus (UEF .97) condensing indoor/outdoor tankless water heater models offer advanced technology that adapts to suit the needs of any household. Our convertible on-demand water heaters are able to operate using either propane or natural gas thanks to a Smart Sense gas control system and can be installed indoors or outdoors with one simple adaptation thanks to the new Versa Vent. Additional features on this natural gas and propane water heater include an easy-to-use interface and Quick Flush function for simplified flushing. With Smart-Circ, Rinnai RXP model water heaters learn your water usage patterns to start circulating hot water on your schedule, anticipating your hot water needs for a shorter wait and saving energy during times when you don't typically use hot water. Unlike tank heaters which accumulate rusty sediments, this tankless water heater has a longer lifespan. Designed to be extremely compact, this small water heater only takes up the space of a small suitcase, letting you reclaim some of your home's most valuable real estate. This Energy Star qualified small hot water heater can be made even smarter with Wi-Fi connectivity through the Control-R module (sold separately).

Review: Fantastic Water Heater - High quality build and tech design. Installation is straight forward thanks to the excellent, detailed instruction manual*. Nonetheless, pre-planning mounting location, materials, electrical service outlet if not already available, is strongly advised. To really maximize energy efficiency, the On Demand BLE Bluetooth button accessory is recommended vs the auto cycle which I found to be cycling every 10mins vs. 28mins as defined by the temperature setting. It was to the point that even the cold water taps were warm, so a lot of wasted energy. Instead, we bought the BLE button accessory ($32) to activate the water recirculation 5 min cycle while getting ready to shower; we turn on shower and with 15 seconds, hot water is flowing saving lots of water and energy!! We are thrilled by knowing we will be saving tons of water and energy year over year. * My only critique is the installation manual is limited in explaining some of the non-critical setup parameter features when configuring the unit for initial operation and does not make clear what you need to set up the Bluetooth on demand operation. I had to call their tech support to figure out the cost effective BLE button option ($32) for on demand set up. Also the app is very limited for the customer personal use features unless you buy a wifi module accessory to allow some remote features set up (more complex installation, $200+). Overall minor quips. The unit is of high build quality and sophisticated technology design that provides hot water efficiently and saves water due to the On Demand recirc feature!! Love it!
Review: Great in line water heater. - My first one died after ten years. I now know they need to be flushed annually to last longer than ten years, especially since I have a well with very hard water.

### ⭐⭐⭐⭐⭐ Great in line water heater.
*by J***R on July 7, 2026*

My first one died after ten years. I now know they need to be flushed annually to last longer than ten years, especially since I have a well with very hard water.

### ⭐⭐⭐⭐ Hot water fast!
*by K***E on August 16, 2025*

I got this with the recirculating back through the cold line. That’s a great feature. Replaced a non condensing heater so had to replace all the exhaust pipes with plastic due to the corrosive exhaust. Easy install since everything else was right there. It remembers usage patterns pretty well, so there’s always hot water within 5 seconds for my morning shower. If you take a one off shower, you may have to wait. One downside of using the cold water for recycle is that it takes a bit to actually get cold water out of the faucet you do the cross over at. We did the bathroom so not the end of the world. My downgrade on rating is on the noise level. We have this in an attic and either the air blower or the recirculating pump has a deep hum that vibrated the whole wall down to our ground floor. I put some sound damping washers on the mounting bolts, which have made it bearable, but you can still hear it every once in a while. Oh! Almost forgot, if you set the recycle to always be ready, it will go on and off through the night, so keep that in mind. Honestly if we had a garage to put this in instead of the attic I’d give it 5 stars.
