What it delivers
The VancEpic V-RHO19K-NG 190,000 BTU Natural Gas Outdoor Tankless Water Heater is an outdoor gas tankless with a 190,000 BTU/h burner and a stated maximum flow of 8.5 GPM.
Worked out from its input, it delivers roughly 6.5 GPM when the water only has to rise 45°F, and 4.2 GPM at a 70°F winter rise: 3 showers at 2 GPM in summer, 2 showers at 2 GPM in winter. Run your house through the planner.
At full fire it burns about 183 cubic feet of natural gas 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.
Outdoor units vent straight out of the cabinet, which saves the vent run and the wall penetration; plan for freeze protection and a pipe cover where winters bite.
Other listed details: features: LED Display; connections: 3/4" npt; material: 8.5GPM 190,000 BTU (Outdoor); model: V-RHO19K-NG; warranty: 2 Year Manufacturer.
The listing gives dimensions of 15.08 in (W) x 24.25 in (H), a weight of 49 lb and manual x1 in the box.
Warranty, per the listing: 2 Year Manufacturer.
