Our take on the Camplux CA318 12L Indoor 3.18 GPM Liquid Propane Tankless Water Heater

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.

Questions and answers

How many fixtures can the CA318 run at once?
At 3.18 GPM it handles one shower or tap comfortably. Running two hot fixtures at the same time will cut flow and temperature.
Does it work in cold climates?
It has anti-freeze protection, but very cold inlet water lowers the achievable temperature rise. It performs best where groundwater stays moderate.
What is included in the box?
The heater, a CSA-approved propane regulator, and a shower head with hose.
Can it replace a tank water heater?
For a small home or single bathroom, yes. For a whole house with multiple bathrooms, its flow rate is too low.
Does it need electricity?
Yes. It uses 120V power for electric ignition and the controls, so it needs a nearby outlet.
Is it for indoor use only?
Yes, the CA318 is designed for indoor installation and needs proper venting.
