Rheem RTG-95DVELP-3 199,900 BTU Propane Tankless Water Heater

What it delivers

The Rheem RTG-95DVELP-3 199,900 BTU Propane Tankless Water Heater is a propane 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. Check it against your own fixtures.

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.

Non-condensing indoor units run hot exhaust and vent in the maker's listed vent system (often stainless Category III), which costs more than plastic.

The listing describes its venting as: direct vent.

From the listing: connectivity: WiFi; material: Stainless Steel; model: RTG-95DVELP-3.

The listing gives dimensions of 13.5 in (W) x 24.2 in (H), a weight of 46.5 lb and display in the box.
