What it delivers
The Ranein TMYD-01020120 68,000 BTU Propane Outdoor Tankless Water Heater is an outdoor gas tankless with a 68,000 BTU/h burner and a stated maximum flow of 3.2 GPM.
At a 45°F rise (mild inlet water to a 120°F set point) it holds about 2.3 GPM, 1 shower at 2 GPM; in winter, at a 70°F rise, about 1.5 GPM, less than one 2 GPM shower. Run your house through the planner.
At full fire it burns about 0.7 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: model: TMYD-01020120; warranty: 2 Year Manufacturer.
The listing gives dimensions of 13 in (W) x 21.7 in (H) and a weight of 18 lb.
Warranty, per the listing: 2 Year Manufacturer.
