What it delivers
The Rinnai RX130iN Condensing Tankless Water Heater is a condensing gas tankless with a 130,000 BTU/h burner and a stated maximum flow of 7.1 GPM.
Flow depends on how cold the incoming water is. Our estimate from its input: 5.5 GPM at a 45°F rise, falling to 3.5 GPM at 70°F, which is 1 shower at 2 GPM on a cold-climate winter day. Check it against your own fixtures.
At full fire it burns about 1.4 gallons of propane an hour. The gas line has to carry that on top of the furnace, range and dryer; a gas fitter sizes the pipe from its length and the total load.
As a condensing unit it vents in the plastic pipe (PVC, CPVC or polypropylene) its manual lists and drains an acidic condensate, usually through a neutralizer.
Also on the listing: connectivity: WiFi; material: Stainless Steel; model: RX130iN; warranty: 5 Year Labor, 5 Year Parts.
The listing gives dimensions of 19 in (W) x 31 in (H), a weight of 54 lb and mount in the box.
Warranty, per the listing: 5 Year Labor, 5 Year Parts.
