Our take on the Rinnai Tankless Water Heater RXP199

The Rinnai RXP199 is a condensing tankless water heater rated at 199,000 BTU and up to 11.1 GPM, sized for roughly 3 to 6 fixtures. Its standout feature is Smart-Circ, a built-in recirculation pump that learns household hot-water patterns and schedules recirculation to cut the wait for hot water. Uniform Energy Factor is 0.98, among the more efficient gas tankless units. It suits larger households replacing a tank or upgrading an older tankless unit; rivals without a built-in pump need added recirculation hardware to match the instant-hot behavior.

Questions and answers

How many fixtures can the RXP199 handle?
Rinnai rates it for about 3 to 6 fixtures, with a maximum flow of 11.1 GPM. Simultaneous showers and laundry are realistic in most homes, but cold inlet temperatures and long runs reduce real output.
What does Smart-Circ do?
It learns your household's hot-water usage and schedules recirculation automatically, so hot water arrives faster at the tap. It uses the built-in pump, so no separate recirculation pump is needed.
Can it be installed outdoors?
Rinnai lists both indoor and outdoor installation for this model. Outdoor placement depends on local code and freeze protection for your climate.
How efficient is it?
It is a condensing unit with a Uniform Energy Factor of 0.98. That is near the top of the gas tankless class, though recirculation adds some gas and electricity use.
What does the warranty cover?
Rinnai offers a limited 15-year warranty on the heat exchanger, 5 years on parts and 1 year on labor. Coverage terms depend on installation and use.
Is it a good upgrade from an older tankless unit?
Yes, mainly for the higher flow and built-in recirculation. Older non-condensing units without a pump need added hardware to deliver hot water as quickly.
Where is the Rinnai Tankless Water Heater RXP199 cheapest?
At Natural Gas Connection, for $2,517.85, as of our latest check.
