The Camplux 3.18 GPM is an indoor natural gas tankless water heater that heats water on demand instead of storing it in a tank. It delivers up to 3.18 gallons per minute and 82,000 BTUs, enough for a small household of two to three people running one fixture at a time. It activates on water flow as low as 0.65 GPM and uses standard 1/2-inch NPT water and gas fittings with a 2.3-inch horizontal vent. Against larger tankless units it is simpler and cheaper to install but has a lower flow ceiling, so simultaneous showers and appliances will strain it. Owners rate it highly for compact size and steady hot water in cabins and small homes.

This indoor tankless water heater runs on natural gas and delivers 3.18 gallons per minute of on-demand hot water. It is sized for a whole house of 2 to 3 people, and is also suited to small cabins and remote apartments. It is activated by water flow rather than water pressure.
It has an oxygen-free copper heat exchanger and a V-type stainless steel burner, with heating efficiency of up to 89.98%. The black glass front panel has an LED touchscreen for setting the water temperature, with a switch between Fahrenheit and Celsius. A 90° wind isolation design helps prevent wind from flowing back down the vent on high floors. The stainless steel vent pipe carries exhaust gases out quickly.
