Camplux CX264WLP 68,000 BTU Propane Tankless Water Heater

What it delivers

The Camplux CX264WLP 68,000 BTU Propane Tankless Water Heater is a propane tankless with a 65,000 BTU/h burner and a stated maximum flow of 2.6 GPM.

Expect about 1.8 GPM with cold winter water (a 70°F rise) and 2.6 GPM when the inlet is milder (45°F rise); that is less than one 2 GPM shower in January. 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 a condensing unit it vents in the plastic pipe (PVC, CPVC or polypropylene) its manual lists and drains an acidic condensate, usually through a neutralizer.

Questions buyers ask

How many showers can the Camplux CX264WLP 68,000 BTU Propane Tankless Water Heater run at once?

From its 65,000 BTU/h input we estimate about 2.6 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 CX264WLP 68,000 BTU Propane Tankless Water Heater need?

At full fire it uses about 63 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.
