What it delivers
The Rheem RTGH-95DVLN-3 199,900 BTU Natural Gas Condensing Tankless Water Heater is a condensing gas tankless with a 199,900 BTU/h burner and a stated maximum flow of 9.5 GPM.
Worked out from its input, it delivers roughly 8.4 GPM when the water only has to rise 45°F, and 5.4 GPM at a 70°F winter rise: 4 showers at 2 GPM in summer, 2 showers at 2 GPM in winter. Size it to your fixtures and climate.
Gas load at full fire: about 193 cubic feet of natural gas an hour. An older half-inch line that already feeds a furnace often can't spare that, so have a gas fitter check the pipe size and run.
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.
The listing describes its venting as: direct vent.
Other listed details: features: LED Display; material: Stainless Steel; model: RTGH-95DVLN-3; warranty: 1 Year Labor, 15 Year Heat Exchanger, 5 Year Parts.
The listing gives dimensions of 17.7 in (W) x 23.7 in (H), a weight of 59.9 lb and product only in the box.
Warranty, per the listing: 1 Year Labor, 15 Year Heat Exchanger, 5 Year Parts.
