Questions & Answers

Does it come with condension line or not? Viene con la linea de condensacion o no? no la quiero.
ByMay 14, 2026
1 Answer | 
Answer This Question

Hello AnaRP, Thank you for your quesiton. The V53De is a non-condensing unit, so it does not produce condensate during normal operation and therefore does not require or include a condensate drain line.

      How far must unit be from window
      ByMay 8, 2026
      1 Answer | 
      Answer This Question

      Hello Robt, The V53DeN has required installation clearances around the unit itself, as well as separate clearance requirements for the exhaust termination in relation to doors, windows, and other openings. Clearances for the unit and vent termination must be installed in accordance with the installation manual and local code requirements. Because window clearance requirements can vary depending on the installation layout and vent location, we recommend consulting a licensed installer to confirm the proper placement for your specific application.

        How do you install connection to outlet to plug in. I can not find plug
        ByApr 21, 2026
        1 Answer | 
        Answer This Question

        Hello Maria, The V53DeN is not designed to plug into a standard outlet. It requires 120 VAC, 60 Hz power from a properly grounded circuit, and a dedicated disconnect switch must be provided for the incoming power. The disconnect should be rated for outdoor use. We recommend working with a licensed installer to ensure the unit is wired correctly and in compliance with local electrical codes.

          Does this unit require a metal cabinet or can it be mounted directly to an exterior metal surface such as an all metal shop building?
          ByMar 30, 2026
          1 Answer | 
          Answer This Question

          Hello Ohdub, The V53De is designed to be wall-mounted using the provided mounting brackets and can be installed on combustible or non-combustible surfaces, provided the installation meets the required clearances and the mounting surface is capable of supporting the unit. We recommend consulting a licensed installer to ensure the unit is securely mounted and installed in accordance with manufacturer requirements and local codes.

            Does the unit turn on when the outside temp gets cold ?
            ByMar 16, 2026
            1 Answer | 
            Answer This Question

            Hello Rinsing, The V53De does not turn on based on outdoor temperature and will only operate when there is a demand for hot water. It does include built-in freeze protection, which activates in cold conditions to help protect the internal components of the unit. However, this protection does not extend to external piping or components, which should be properly insulated or protected from freezing. We recommend consulting a licensed installer to ensure the unit is properly installed and protected for your specific climate and application.

              Answer This Question

              Hello Jaemack, This unit does not include a controller, but one can be purchased separately. The compatible controller for this unit is the MC-91-2W.

                Is it safe to install this under the sink? Must it exhaust out side. Does it produce excess heat?
                ByMar 3, 2026
                1 Answer | 
                Answer This Question

                Hello Stanley, We do not recommend installing the unit under a sink. The unit requires specific installation clearances and uses room air for combustion, so it must be installed in a location that provides adequate airflow. In addition, combustion air must be free of corrosive compounds commonly found in products such as aerosol sprays, detergents, bleach, and cleaning solvents. The unit must also be properly vented to the outdoors in accordance with the installation and operation manual and all applicable local codes. We recommend contacting a licensed installer to evaluate your hot water needs and determine the most appropriate unit and installation method for your application while ensuring all installation requirements and local codes are followed.

                  Works great. Very satisfied the only issue or question that is not addressed in the owners manual is the grey threaded port on the bottom that the 120 volt wires come through does not have a threaded cap or any instructions on the size. It does include a split rubber stopper but no threaded cap. I don't feel like calling them and going through a bunch of prompts to reach someone so I just left it. Heater works awesome.
                  by
                  Response from Rinnai Product ExpertApr 25, 2025
                  ​The grey threaded port at the bottom of your Rinnai V53DeN tankless water heater is designed for the electrical power connection. The included split rubber grommet is intended to provide strain relief and maintain a weather-resistant seal when routing the power cable through this port. This setup is typical for outdoor installations where the power cable is not enclosed in conduit.​

                  The installation manual illustrates this configuration, showing the power cable passing through the rubber grommet without utilizing the threaded portion of the port .​
                  Rinnai America Corporation

                  If your local electrical code requires the use of conduit for outdoor installations, or if you prefer to use conduit for added protection, you can utilize the threaded portion of the port. In such cases, a standard ½-inch National Pipe Thread (NPT) conduit fitting is typically compatible. You can find appropriate fittings, such as weatherproof strain relief connectors or conduit hubs, at most hardware stores.​

                  If you're not using conduit and the installation is in a dry, protected area, the rubber grommet alone should suffice. However, if you have any concerns about meeting local code requirements or ensuring optimal protection for the electrical connection, consulting with a licensed electrician is advisable.​

                  For more detailed information, you can refer to the installation manual for the Rinnai V53DeN RinnaiAmerica

                  Misleading Product Description - In My Opinion
                  Product says "WI-FI Ready" and I assumed download App and it will connect. Not true. One needs separate controller - $100 - plus install to work with WI-FI. Heater works without controller at 120 degrees per tech support. IMHO Misleading.

                    This water heater is awesome to date. I like the fact that it does not require a remote control. The factory setting is awesome for hot water. More instruction should be include for adjustments, but maybe they don’t want one to have setting options.

                    I've had it in for a few weeks and it works great. We have a small home 1 bath, kitchen with dishwasher and washing machine, plenty of hot water. It's quiet I don't even know it's working.The unit itself is clean and reasonable small, we mounted outside and we built a cover to protect a bit from the elements. Install was simple mainly because we were replacing the old Rinnai unit with a new one and everything was in place. This seems to be a good value in my opinion. I had a company quote me 1800.00 for another unit installed, this until from Home Depot was about 600.00 to our door plus a hour labor to install.

                    It was quite easy to install. works quite well, supplying enough hot water for two apartments with four bathrooms to kitchens, washer dryers. We bought two of those for different apartments, and all of them seem to be working quite well.

                    Unit performs erratically. Temperature of output does not stabilize for several minutes. But over the ten days following installation, output was on some days scalding hot, some days only lukewarm under identical settings.

                    Hello Michael,
                    We’re sorry to hear about your experience, and we understand how frustrating inconsistent water temperature can be. Tankless systems rely on several factors such as flow rate, incoming water temperature, and installation configuration, and when any of these are not optimized it can affect temperature stability. This isn’t the performance we want customers to have, and we’d appreciate the opportunity to learn more about your setup and see if there’s anything we can do to help. Please reach out to our customer support team by phone or via live chat on rinnai.us. Thank you for sharing your feedback. RinnaiAmerica

                    Waste of money
                    I've had this unit for about a year now to replace my old unit. Ever since I replaced it with this unit, I've had nothing but problems. Every other week it seems to throw either a code 11 or a code 12. I have had the unit inspected several times, each time concluding that there is nothing wrong with it. I am frustrated. I am tired. Please do yourself a favor and warm your water by burning the $600 you'd spend to warm your water.

                    We’re very sorry to hear about your experience and understand how frustrating it is to deal with recurring error codes. Codes 11 and 12 are related to ignition and flame detection, and repeated issues like this are understandably concerning.
