What it delivers
The Camplux CA528 150,000 BTU Natural Gas Tankless Water Heater is a non-condensing gas tankless with a 150,000 BTU/h burner.
Flow depends on how cold the incoming water is. Our estimate from its input: 5.1 GPM at a 45°F rise, falling to 3.3 GPM at 70°F, which is 1 shower at 2 GPM on a cold-climate winter day. Run your house through the planner.
Gas load at full fire: about 145 cubic feet of natural gas an hour. An older half-inch line that already feeds a furnace often can't spare that, so have a gas fitter check the pipe size and run.
Non-condensing indoor units run hot exhaust and vent in the maker's listed vent system (often stainless Category III), which costs more than plastic.
Also on the listing: connections: 3/4" npt; model: CA528.
The listing gives dimensions of 14.92 in (W) x 6.69 in (H) and a weight of 31.3 lb.
