What it delivers
The Rheem RTG-70XLP-3 160,000 BTU Propane Outdoor Tankless Water Heater is an outdoor gas tankless with a stated maximum flow of 7.0 GPM.
The listing doesn't state the BTU input, so its flow at your temperature rise can't be estimated from its own figures. The planner shows what your house needs.
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.
The listing describes its venting as: Outdoor installation.
Also on the listing: material: Stainless Steel; model: RTG-70XLP-3; warranty: 1 Year Labor, 15 Year Heat Exchanger, 5 Year Parts.
The listing gives dimensions of 13.5 in (W) x 20.75 in (H), a weight of 39.3 lb and display in the box.
Warranty, per the listing: 1 Year Labor, 15 Year Heat Exchanger, 5 Year Parts.
