        Q:Do any of the water or gas supply valves come with this water heater? What is in the box?
        by|Jan 20, 2022
        1 Answer
        Answer This Question

        A:  No. HD web site does not say if they are or are not. Rinnai CS said they are not. Rinnai CS said it is detailed on p. 5 of the owners manual. Really? A buyer has to read the installation manual to tell what's in the box! Plus this is a 2015 made unit .

          Worth The Extra Initial Cost
          I switched from an electric tank to a high efficiency gas tankless unit. I love the unending hot water, but even better than that, my first full month my electric bill dropped by $66 and my gas bill only went up by $3.85! It will have completely paid for itself in about 4 years.

            Love having endless hot water!
            We have had it installed for about 6 months. Meets and exceeds our expectations.

              Hot water only when you need it!
              Unlimited hot water when needed. Not wasting energy + money keeping a tank full hot for the 90% of the time it isn't being used. I've had it 4 months now + couldn't be happier!

                No valves or remote temp controller
                Opened the box and found out that no valves or remote temp controller are included. I bought a Rinnai after my plumber recommended it. He said every unit he's ever installed came with valves and a temp controller. Had to go buy both. Very frustrated.

                    Reliable
                    In the end, endless hot water. It was difficult to install and time consuming.

                      Outdoors nat gas hotwater heater
                      Even though we have not had our Rinnai hotwater heater very long we are VERY well please with it's performance. Again, even though we do not have a lot experience with the on demand hotwater heater we believe the savings from going ondemand hotwater from an outside hotwater trying to maintain temperature all the time will be very significant.

                        The application for outdoors was my preferred choice , looks good on the exterior of home, installation completed was on July 12 2020, It has been working great , no problems well worth the expense, looking forward in seeing the savings on my gas bill.
