Questions & Answers

Hi Edwin, as long as nothing has changed, with the type of unit, going from condensing to non-condensing, and it is in good condition, you can reuse the same venting.

Will this model fit model RL75i?
Hello, We recommend discussing any changes or planned upgrades to your home's hot water needs with a licensed installer to ensure the replacement unit is properly sized for your application. If there have been no significant changes to your hot water demand, the RE180iN would be the current comparable replacement model. Your installer should verify compatibility with the existing installation and determine whether any modifications are required.
Does this unit have an energy star rating ?
Hello, Yes, the RE199i is energy star certified and boasts a Uniform energy factor of 0.82.
Avoid this Tankless at all cost!!! We have had nothing but problems with constantly throwing code 11s on a new unit and not igniting after multiple plumbers, and gas company working with Rinnai to fix it and Rinnai refuses to find a solution!
Does this unit have a back up heat coil?
Hello Patrick, No, the RE199iN does not have a backup heating coil or heating element. The RE199iN is a natural gas fired tankless water heater and uses its gas burner and heat exchanger to heat the domestic water supply. The unit does include built-in freeze protection when electrical power is available, but this system is designed to help protect the water heater from freezing and does not serve as a backup source for heating domestic water.
what are venting requirements
Hello jimc, The RE140iN is an indoor, non-condensing tankless water heater that requires venting to the outdoors using an approved vent system. The specific vent diameter, maximum vent length, and allowable number of elbows depend on the installation and must comply with the Installation and Operation Manual. We recommend consulting a licensed installer to determine the appropriate vent configuration for your application and ensure compliance with local codes.
Will this unit run on propane ?
Hello GBthreeak, The High Efficiency Non-Condensing 9.8 GPM Residential 199,000 BTU Interior Natural Gas Tankless Water Heater is designed to run on natural gas. The unit may be converted to Liquid Propane Gas with the use of a conversion kit by a licensed professional. If you require a propane tankless water heater, the model is available in a propane version. Please search model# RE199iP to locate it.
