Rinnai RUR199iN Natural Gas Condensing Tankless Water Heater

What it delivers

The Rinnai RUR199iN Natural Gas Condensing Tankless Water Heater is a condensing gas tankless with a stated maximum flow of 11.0 GPM.

The listing doesn't state the BTU input, so its flow at your temperature rise can't be estimated from its own figures. The planner shows what your house needs.

It recovers heat from its own exhaust, so it runs plastic venting and needs a condensate drain; check the vent lengths its manual allows.

Also on the listing: features: Wi-Fi Monitoring, Recirculation Technology; connectivity: Wifi; recirculation: built-in recirculation; model: RUR199iN.

The listing gives dimensions of 18.5 in (W) x 31.3 in (H) and a weight of 84 lb.

Warranty, per the listing: Residential Factory Warranty - 120 months (heat exchanger), 12 months (labor), 60 months (parts).
