Our take on the Rinnai RX199i Condensing Tankless Water Heater

The Rinnai RX199i is a condensing, gas-fired tankless water heater rated at 199,000 BTU/h, the top of Rinnai's residential line. Its condensing design captures heat that conventional tankless units vent away, so it runs at higher efficiency and suits homes with high simultaneous hot-water demand. Against non-condensing rivals it needs a drain for condensate and a proper vent, which adds install work. Owners of Rinnai tankless units generally report steady hot water and long service life, with maintenance and install cost as the common complaints.

Questions and answers

Is the RX199i worth it over a non-condensing tankless unit?
If your home has high hot-water demand and you can route a condensate drain, the condensing design is the more efficient choice. A non-condensing unit is simpler to install but less efficient.
How much hot water can it deliver?
At 199,000 BTU/h it is Rinnai's highest-capacity residential model, sized for large homes with multiple bathrooms. Actual flow depends on incoming water temperature and the temperature rise you set.
What does installation require?
A gas line sized for 199,000 BTU/h, proper venting for a condensing unit, and a drain for condensate. Rinnai recommends a qualified installer.
Does it need maintenance?
Rinnai recommends periodic descaling, especially with hard water, to keep the heat exchanger efficient. An annual check is common practice.
What is in the box?
The heater itself with Rinnai's factory warranty. Venting, gas fittings and condensate parts are typically supplied separately by the installer.
Where is the Rinnai RX199i Condensing Tankless Water Heater cheapest?
