What it delivers

The Camplux CX264WNG 68,000 BTU Natural Gas Tankless Water Heater is a non-condensing gas tankless with a 68,000 BTU/h burner.

Worked out from its input, it delivers roughly 2.9 GPM when the water only has to rise 45°F, and 1.8 GPM at a 70°F winter rise: 1 shower at 2 GPM in summer, less than one 2 GPM shower in winter. Size it to your fixtures and climate.

At full fire it burns about 66 cubic feet of natural gas an hour or 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.

Condensing means cooler exhaust in plastic vent pipe and a condensate line to a drain; most installs add a neutralizer cartridge on that line.

Other listed details: connections: 1/2" npt; vent size: 3" vent; material: Copper, Stainless Steel; model: CX264WNG.

The listing gives dimensions of 5.9 in (W) x 13.7 in (H) and a weight of 19.1 lb.

Questions buyers ask

Is the Camplux CX264WNG 68,000 BTU Natural Gas Tankless Water Heater big enough for two showers?
From its 68,000 BTU/h input we estimate about 2.9 GPM at a 45°F rise and 1.8 GPM at a 70°F rise, so 1 two-GPM shower with mild inlet water and 0 in a cold winter. The maker's flow chart for this model is the final word.
What size gas line does the Camplux CX264WNG 68,000 BTU Natural Gas Tankless Water Heater need?
At full fire it uses about 66 cubic feet of natural gas an hour or 0.7 gallons of propane. The pipe size depends on the length of the run and every other gas appliance on it; the maker's manual and a licensed gas fitter decide it.
