Camplux WA686LP 199,000 BTU Propane Outdoor Tankless Water Heater

What it delivers

The Camplux WA686LP 199,000 BTU Propane Outdoor Tankless Water Heater is an outdoor gas tankless with a 199,000 BTU/h burner and a stated maximum flow of 8.4 GPM.

Flow depends on how cold the incoming water is. Our estimate from its input: 6.8 GPM at a 45°F rise, falling to 4.4 GPM at 70°F, which is 2 showers at 2 GPM on a cold-climate winter day. Size it to your fixtures and climate.

The line must deliver about 2.2 gallons of propane an hour when it fires flat out. The requirement calculator adds it up; a licensed fitter confirms the pipe.

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.

Also on the listing: material: Stainless Steel; model: WA686LP.

The listing gives dimensions of 6.5 in (W) x 22.24 in (H) and a weight of 40.8 lb.
