What it delivers
The Rheem RTG-95XLP-3 199,900 BTU Propane Outdoor Tankless Water Heater is an outdoor gas tankless with a 199,900 BTU/h burner and a stated maximum flow of 9.5 GPM.
At a 45°F rise (mild inlet water to a 120°F set point) it holds about 6.8 GPM, 3 showers at 2 GPM; in winter, at a 70°F rise, about 4.4 GPM, 2 showers at 2 GPM. Size it to your fixtures and climate.
At full fire it burns about 2.2 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 an outdoor model it mounts on an exterior wall and needs no vent pipe; in freezing climates check the maker's freeze protection and cover the connections.
The listing describes its venting as: Outdoor installation.
From the listing: material: Stainless Steel; model: RTG-95XLP-3; warranty: 1 Year Labor, 15 Year Heat Exchanger, 5 Year Parts.
