The Camplux CA318 is a propane tankless water heater rated at 3.18 GPM and 82,000 BTU, meant for indoor residential use. It heats water on demand through an oxygen-free copper heat exchanger at up to about 90% efficiency, with a 95–149°F range and electric ignition. It suits a cabin, small home, or a single point of use like a shower, where a full tank unit is overkill. Against bigger whole-house tankless models it delivers less flow, so running several fixtures at once will strain it. Owners rate it well overall, with most praise going to easy installation and steady hot water at low flow.

Owners rate the CA318 highly, mostly for straightforward installation and reliable hot water in small setups. Complaints center on flow dropping when more than one tap runs and on the unit's limits in cold climates.
