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!!

    This product is a mess. Within three years or less I am having so many troubles that is unacceptable for a new product. I will highly suggest no one use this product in their house.

    Continuous hot water
    So far we are pretty happy with this new tankless water heater. The only part that keeps it from five stars for me is that it takes quite a bit of time from the time it starts to heat to the time it cycles hot water to where you need it. I'm sure there's probably some kind of solution for this too keep from wasting so much water but it must be an additonal purchase. Other than that it's a pretty decent and low maintenance product.

    Tankless water heater
    Our first experience with a tankless hot water heater--we moved into a new house with one. It works great, lots of hot water once it gets started. Downside is that you do have to run the water for a while before the hot water gets to you, so you do use more water than with a hot water tank. If I had a choice between tankless and tanked, I prefer tanked. My wife on the other hand likes the tankless. Decent warranty with our model, so no real complaints.

    Go Tankless!
    Loved my tankless water heater! Takes a minute or two to get hot water, then it’s endless long showers. Have to be careful to ensure fuel efficiency.

    No hot water at times
    We are frustrated how often the water goes from hot to cold...and in the kitchen the water won’t get hoy at all. The solution we were advised by home builder is to either to clean the tiny filter which is hard to get to, or unplug the heater to reboot. We are having to deal with this about once per week
