Questions & Answers

Does installation of this unit require or would it benefit from a small thermal expansion tank?
ByApr 13, 2026
1 Answer | 
Answer This Question

Hello KenM, The REP160iP does not require an expansion tank as part of the unit installation. However, an expansion tank may be required depending on the home’s plumbing configuration and local plumbing codes, such as in closed domestic water systems. We recommend consulting a licensed professional installer to evaluate your plumbing setup and determine whether an expansion tank is needed.

    Not sure what you mean by “vent tube,” but if you're referring to tubing for condensation,, we recommend using a clear ½" ID vinyl or similar condensation tubing

            Can this be installed by homeowner?
            ByMay 8, 2023
            1 Answer | 
            Answer This Question

            Hello Dave, Rinnai does recommend the installation be completed by a licensed and trained professional but is not required. When installing a Rinnai tankless water heater, a licensed technician would ensure proper venting, gas pressures (both the supply pressure and internal calibrations of the lo and hi fire settings), water pressures, electrical and drain lines are done properly. A locally licensed professional would also be expected to know and follow any local codes and/or pull any required permits. Please be advised that if there are any manufacturing defects that need to be resolved under warranty, we do require that a licensed professional is involved to assist with diagnosis and repairs needed. Thank you, Brittany

                Works like a charm.
                I like that the unit learns when I need hot water, and circulate water to my kitchen faucet at a specific time

                  We’ve had it for six months. It runs more often, consuming more gas, however that’s what it has to do to keep a line charged with hot water. It’s a trade-off. You have to accept if you have a large home and want on-demand hot water available everywhere.

                    Definitely meets my expectations. I like the instant on so hot water is at tap right away. I would prefer a separate hot water feedback loop from sink vs using cold water line for feedback.

                        Great product
                        We've had our propane fired tankless for 4 months and it's been absolutely awesome. We wish we would've done it years ago

                            It takes a little bit to warm up but then it is continuous. We love it especially when we have company and do not run out of hot water
