What it delivers
The LiberLive HKRV-WH01 130,000 BTU Natural Gas Outdoor Tankless Water Heater is an outdoor gas tankless with a 130,000 BTU/h burner and a stated maximum flow of 5.3 GPM.
Flow depends on how cold the incoming water is. Our estimate from its input: 4.4 GPM at a 45°F rise, falling to 2.9 GPM at 70°F, which is 1 shower at 2 GPM on a cold-climate winter day. Size it to your fixtures and climate.
The line must deliver about 125 cubic feet of natural gas an hour when it fires flat out. The requirement calculator adds it up; a licensed fitter confirms the pipe.
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: connections: 3/4" npt; material: Copper, Metal; model: HKRV-WH01.
The listing gives dimensions of 14.2 in (W) x 21.7 in (H).
