    Works great!I installed this myself. Not super easy for a homeowner but the directions were straight forward. Works great.

    This is a great water heater The water heater works great and isn’t too hard to install just make sure you keep in mind that you’re going to spend about $400 at Home Depot to get the rest of what you need to hook it up however the space savings in my closet over a traditional 60 gallon water heater are worth every penny!

    Great replacement for our Noritz Tankless Water HeaterWe had a Noritz N-063S that was having problems after 12 years of use. We replaced it with this Rinnai RU130iN and it’s working great. The old unit pulled in the combustible air for room where it was installed. The new unit uses concentric piping and pulls the combustible air from the outside through the same 5″ vent pipe used for the exhaust (exhaust through an inner 3″ pipe and combustible air for the outer 5″ pipe). And since it’s a high efficiency, condensing unit, the exhaust is warm/not hot so you can use plastic piping. I used the Rinnai 223176PP and it worked perfectly for my installation. The only issue I’ve had thus far is getting the unit to work with the Control-R wireless controller. Otherwise it was easy to install as a replacement, easy to vent, and has worked great thus far.

    You have to go online to see how to set the temperature at 140

    Love it!This is the first time we bought a tankless water heater. My husband installed it in a few hours & we like it very much!

    As describedI installed the water heater in a 12×8 shed where I installed water filters, UV, washing machine and shower stall for our campers for the past 5 months. Used it daily with a 20lb propane tank. Conversion was easy. Switching propane tanks sometimes causes air long that takes a moment to expel, so bigger tanks would be a good idea in my case for next year.
