Our take on the Rinnai Tankless Water Heater - RX160

The Rinnai RX160 is a natural gas condensing tankless water heater rated at 160,000 BTU and up to 9.0 GPM with a valve, enough for roughly 2 to 5 fixtures. It runs at a 0.97 Uniform Energy Factor, so almost all the heat goes into the water, and it is small enough to mount indoors or outdoors. It suits households replacing a tank or upsizing hot water capacity. Against non-condensing tankless units it is more efficient; against larger condensing models it gives up some flow for a smaller footprint.

Questions and answers

How many fixtures can the RX160 handle?
Rinnai rates it for about 2 to 5 fixtures. In cold climates incoming water is colder, so real output is lower than in warm regions.
Does it work outdoors?
Yes, Rinnai lists indoor and outdoor installation. Outdoor units in freezing climates need freeze protection.
What is the flow rate?
Up to 9.0 GPM maximum with a valve. Without the valve the rated flow is lower.
What warranty does it carry?
A limited 15-year warranty on the heat exchanger, 5 years on parts and 1 year on labor.
Does a condensing tankless heater need a drain?
Yes. Condensing models produce acidic condensate that must be routed to a drain or neutralizer.
Is it a good upgrade from a tank heater?
It gives endless hot water and higher efficiency, but installation costs more because of venting, gas sizing and condensate lines.
Where is the Rinnai Tankless Water Heater - RX160 cheapest?
At Natural Gas Connection, for $1,952.51, as of our latest check.
