Not As Advertised
No WiFi compatibility - must have two optional add-ons, a wired Remote Control and a WiFi Gateway. Not circulation pump control. Not able to set temperature below 120F without OPTIONAL Remote Control - and then lowest setpoint is 115F - no lower! Remote Control is not well documented - no user guide! Unit is small enough to be installed in standard 16" wall - but manufacturer stipulates a 6" clearance from BOTH combustibles & non-combustibles! Semi-flush mounting only possible when installed in Noritz's RB-510 recess box.

    Good so far. Hot, fast. keeps going. We replaced a tank and haven't noticed a big difference. Still remodeling so won't really know until all of the appliances and another bath are turned on.

    Had professionally installed. Didn’t take long since I was replacing a piece of junk Navien. Much quieter and larger capacity than the navien also. Only been a couple of months but will report back to update. So far no complaints!!

    Easy install and plenty of hot water. Definitely an upgrade to our previous on demand water heater. We went from 141k BTU to 181k BTU. Great choice.

    Love the hot water never runs out, I live in a studio and the small water heater took some of the space so having this one that went outside was great. No need for venting .

    The unit is quit and easy to install. The water flow is much better then my last unit. Although it takes 2-3 minutes for hot water to flow through the system. May it because of winter.
