Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For a propane water heater, safety means CSA approval, overheat and flame-failure protection and a stated shutoff temperature where the listing gives one. Three of the five picks state a warranty term, and four carry CSA approval.

How to choose the best portable hot water heater for camping
Match flow to the shower, not the tank
Flow is the figure that sets the shower. The Camplux 2.64 GPM Propane Heater lists 2.64 GPM, the two Amzgachfktch 6L picks list 1.58 GPM, and the Camplux 5L Water Heater lists 1.32 GPM. The Hike Crew Propane Water Heater states no flow figure, so its shower strength is a guess. A higher flow suits a full shower, while a lower flow suits quick rinses and camp dishes.
Check the pressure your water source can give
Every pick here needs water pressure to start. The two Amzgachfktch 6L picks start at 2.5 PSI, the Camplux 5L Water Heater starts at 3.0 PSI, and the Camplux 2.64 GPM Propane Heater lists 3.6 to 110 PSI. The Camplux 5L listing says its 3.0 PSI start works with a small 12V water pump or a gravity water bag, the setup for water from a bucket rather than a tap. See our power station guides if your camp runs on a power station.
| Heater | Start pressure | Shutoff temperature |
|---|---|---|
| Camplux 2.64 GPM Propane Heater | 3.6 PSI | 176°F |
| Camplux 5L Water Heater | 3.0 PSI | Not stated |
| Amzgachfktch 6L Water Heater | 2.5 PSI | Not stated |
| Hike Crew Propane Water Heater | Not stated | 149°F |
Read the safety listings before the heat output
Heat output runs from 40,000 BTU on the two 6L picks to 68,000 BTU on the Camplux 2.64 GPM Propane Heater, and the Camplux 5L Water Heater states no BTU figure. Output alone does not make a pick safe: four of the five picks carry CSA approval. The two 6L picks list 6-in-1 protection covering overheat, low water flow, dry combustion, anti-freezing, high water pressure and flame failure, and the 5L Camplux lists 6-in-1 protection too. The Hike Crew Propane Water Heater states no CSA approval but lists an automatic shutoff over 149°F, a water-flow sensor and tilt protection. A solar shower bag is the no-fuel alternative; see our best solar shower for hot weather guide.
Count the weight you will carry
These heaters hang from a bracket. The Camplux 5L Water Heater lists 10 lb, the two 6L picks list 12 lb, and the Camplux 2.64 GPM Propane Heater lists 23 lb in its bullets. The Hike Crew Propane Water Heater gives no clean weight figure: its spec table lists a weight with many decimal places and dimensions of 80.0 inches on every side, which does not match the 12.5 by 8.5 by 5 inch size in the same listing. A folding handle helps on every pick that lists one, and the Hike Crew adds a carry case. For propane gear, see our portable power station vs propane generator comparison.
Sizing Notes
- Match start pressure to your water source: the 6L picks start at 2.5 PSI, the 5L Camplux at 3.0 PSI and the 2.64 GPM Camplux at 3.6 PSI.
- Match flow to the job: listed flows run from 1.32 GPM to 2.64 GPM, and the 6L and 5L picks ship with a shower head.
- Check the propane tank the listing names: the 6L picks run on a standard 20 lb liquid propane tank.
- Keep the heater outdoors and drain it before storage in cold weather, as the 6L listings advise.
- Match the power the listing names: two D-size batteries for the Camplux 5L and the 6L picks, or a 12V car adapter for the Hike Crew.
FAQ: power away from the grid
How long does a water heater last?
None of the listings in this group states a service life. Compare warranty terms instead: three picks state a 1 year term and two state no term.
How to choose a hot water heater?
Start with flow and start pressure, then check safety listings and warranty. The Camplux 2.64 GPM Propane Heater leads this group: it states the highest flow, CSA approval and a 1 year warranty.
What size water heater do I need for camping?
The picks here come in 5L and 6L sizes, with flows from 1.32 GPM to 2.64 GPM. A 5L pick suits a single shower setup, while a 6L pick suits longer showers and shared use at a base camp.
What is a standard size water heater?
No standard size is stated. The camping picks here are 5L and 6L units; pick the one whose flow and start pressure match your water source.
What is a good water heater for camping?
A good pick states flow, start pressure, CSA approval and a warranty term. The Camplux 2.64 GPM Propane Heater states all four: 2.64 GPM, 3.6 PSI, CSA approval and a 1 year warranty.
