Our Picks: Best Propane Tankless Water Heaters For Camping reviews
1. CAMPLUX 2.64 GPM Heater with Pump Pack: Best All-in-One Setup
This CAMPLUX package pairs a portable propane heater with a 3.3 GPM pump kit and quick-connect hoses. That combination can simplify camp setup when you are drawing water from a source that needs a pump. The heater is rated for up to 2.64 GPM, making it one of the higher-flow options in this group.
At 15 pounds and 12.9 by 5.9 by 18.5 inches, it is designed to be carried and packed rather than installed as a permanent household appliance. Its two-in-one control knob lets you adjust water flow and propane power. The product description also lists protections for flame failure, dry combustion, and high pressure.
The included pump kit is the main reason to choose this model over a basic heater. It may be a practical fit for campers who want a more complete outdoor shower setup in one package. Keep in mind that the pump and heater still need a suitable water source and propane supply, and the 15-pound heater is not as light as the 10-pound CAMPLUX option below.
Pros:
- Includes a 3.3 GPM pump kit and quick-connect hoses.
- Up to 2.64 GPM flow for outdoor hot-water tasks.
- Adjustable water-flow and propane-power controls.
- Lists flame-failure, dry-combustion, and high-pressure protections.
Cons:
- Heavier than the smallest heater in this comparison.
- Its maximum flow depends on having a suitable water supply and setup.
Verdict: Choose this CAMPLUX if you want a higher-flow portable heater and value having a pump kit included.
2. CAMPLUX 5L Portable Water Heater: Best Lightweight Pick
This compact CAMPLUX heater weighs 10 pounds and has a folding handle, which makes it a straightforward option for campers who want to keep carried gear light. Its rated output is 1.32 GPM, below the higher-flow models in this roundup. That level may suit a single outdoor shower or basic washing tasks, depending on the water temperature and pressure available.
The heater is described as starting at 3.0 PSI and operating with two D-size batteries. Its package includes an on/off shower head, a five-foot gas regulator, and hoses. The stated low-pressure start may be useful for a setup using a small water pump or gravity-fed water bag, but you should check the specifications against your actual water source before buying.
Compared with the 6L models, this one emphasizes lower weight and a smaller 5L format rather than a higher listed flow rate. The product description identifies it as CSA certified and lists several safety protections. As with any propane appliance, follow the manufacturer’s instructions and use it only in an appropriate outdoor setting.
Pros:
- Lightest listed option at 10 pounds.
- Folding handle supports carrying and storage.
- Listed 3.0 PSI starting pressure for low-pressure setups.
- Includes a shower head, gas regulator, and hoses.
Cons:
- Its 1.32 GPM rating is the lowest in this group.
- Requires two D-size batteries for operation.
Verdict: Pick this model if portability is your priority and its more modest flow rate suits your camp routine.
3. Amzgachfktch 6L Portable Heater: A Compact Mid-Flow Option
This 6L portable heater is rated for up to 1.58 GPM and has a listed maximum output of 40,000 BTU per hour. It weighs 12 pounds, with a foldable handle and a slim body measuring 11.8 by 5.3 by 17.3 inches. The package description lists a shower head, gas regulator, garden-hose adapter, and installation hardware.
The listed minimum starting pressure is 2.5 PSI. That figure matters if you plan to use a low-pressure pump or a gravity-fed source: if the supply does not meet the requirement, the heater may not start or may have trouble maintaining a steady temperature. The unit uses two D-cell batteries for electronic ignition and is described for use with a standard 20-pound liquid propane tank.
Its flow rating sits between the lighter 1.32 GPM CAMPLUX and the 2.64 GPM models. The product description lists protections for overheating, low water flow, dry combustion, freezing, high water pressure, and flame failure. It is a reasonable fit for campers who want a compact heater with more listed flow than the smallest option, but check the included components and pressure needs for your particular setup.
Pros:
- Compact 12-pound design with a foldable handle.
- Rated up to 1.58 GPM with 40,000 BTU/hour output.
- Includes a shower head, regulator, hose adapter, and hardware.
- Lists multiple protection features and electronic ignition.
Cons:
- Requires water pressure of at least 2.5 PSI to start properly.
- Uses two D-cell batteries for ignition.
Verdict: Consider this 6L model if you want a compact mid-flow heater and can meet its stated water-pressure requirement.
4. Amzgachfktch Slim 6L Heater: Another 1.58 GPM Choice
This Amzgachfktch listing shares several key specifications with the other 6L model here: a 1.58 GPM maximum flow, 40,000 BTU/hour output, 12-pound weight, and compact 11.8-by-5.3-by-17.3-inch dimensions. It also lists a foldable handle and includes a shower head, gas regulator, hose adapters, and hardware kit.
The product description states a minimum starting pressure of 2.5 PSI and says the heater uses two D-cell batteries for electronic ignition. It is described for use with a standard 20-pound liquid propane tank. Its listed protections include overheating, low water flow, dry combustion, freezing, high water pressure, and flame failure.
Because the supplied specifications closely match the other Amzgachfktch 6L option, there is no clear performance advantage between the two based on the available product details. Compare the current listing information and included accessories before choosing. Either way, water pressure is a key compatibility check, especially if you rely on a small pump or gravity-fed source.
Pros:
- Compact, slim format with a foldable handle.
- Listed 1.58 GPM flow and 40,000 BTU/hour output.
- Includes a shower head, regulator, adapters, and hardware.
- Lists multiple safety protections.
Cons:
- Needs at least 2.5 PSI of water pressure to start properly.
- Its stated specifications largely overlap with the other 6L option.
Verdict: This is a suitable alternative to the other Amzgachfktch 6L heater if its listing and included accessories best fit your needs.
5. CAMPLUX 2.64 GPM Heater: Best for Higher Listed Flow
This CAMPLUX heater is rated for up to 2.64 GPM and has a maximum output of 68,000 BTU per hour. That higher listed flow may be useful for a camp shower setup with a suitable water supply. At 23 pounds, however, it is substantially heavier than the other models in this comparison, so it is better suited to car camping or a more permanent outdoor setup than trips where every pound matters.
The product description lists a mounting bracket and says installation takes about 15 minutes. It also describes CSA safety-standard approval, flame-failure protection, overheating protection, and an anti-freezing drain plug that can drain residual water. It states that the heater automatically decreases water pressure between 3.6 and 110 PSI.
This model is a higher-flow alternative to the smaller 6L heaters, but its weight is an important trade-off. The product instructions also warn against using Teflon tape between the gas regulator and gas inlet pipe and advise checking for gas leaks before operation. Follow the included instructions closely and use the heater outdoors in a suitable, well-ventilated location.
Pros:
- Rated for up to 2.64 GPM and 68,000 BTU/hour.
- Includes a mounting bracket.
- Lists flame-failure and overheating protection.
- Anti-freezing drain plug helps remove residual water.
Cons:
- At 23 pounds, it is the heaviest option in this roundup.
- Requires careful setup and attention to the gas-connection instructions.
Verdict: Choose this CAMPLUX if higher listed flow matters more than a lightweight carry, and you have a stable place to set it up.
How to Choose a Propane Tankless Water Heater for Camping
Match the flow rate to your routine
Flow rate, shown in gallons per minute (GPM), gives you a way to compare the listed water output of these heaters. The models here range from 1.32 to 2.64 GPM. A higher rating may be helpful for a stronger shower or more demanding cleanup, but the actual result also depends on your water supply, incoming water temperature, and setup. For a simple rinse or occasional camp use, a lower-flow unit may be enough.
Check your water source and pressure
Portable heaters need water to flow before they can heat it. Some listings specify a minimum starting pressure: the CAMPLUX 5L lists 3.0 PSI, while both Amzgachfktch 6L listings specify 2.5 PSI. Check those requirements against your pump or water source before buying. If your setup cannot provide the stated pressure, the unit may not start or may have trouble delivering steady hot water.
Account for the full setup, not just the heater
Think through what you will need at camp: a propane tank, water source, hoses, shower head, and, for some setups, a pump. The CAMPLUX 2.64 GPM heater with pump pack includes a 3.3 GPM pump kit and quick-connect hoses. Other products list different included accessories, so confirm the package contents rather than assuming every model includes the same equipment.
Balance portability with output
Weight ranges from 10 to 23 pounds among these picks. If you are carrying gear a long distance, the lightest model may be more practical. For car camping, a heavier heater with a higher listed flow could be a better trade-off. Also consider the unit’s size and whether the handle or mounting options suit the way you pack and store your gear.
Understand ignition and power needs
Some models need batteries for ignition. The CAMPLUX 5L and both Amzgachfktch 6L descriptions specify two D-cell batteries. The supplied details for the other models do not state their ignition power needs, so check the product instructions or listing before you head out. Plan for spare batteries when a heater’s operation depends on them.
Put safety and outdoor use first
These products are described as outdoor heaters. Use them only in an appropriate outdoor setting, follow the manufacturer’s installation and operating instructions, and keep the propane connection secure. Check for gas leaks as directed, and never operate a propane heater in an enclosed space. If a model has a specific warning about how to connect the regulator, follow that warning rather than relying on general plumbing practices.
Consider freezing and storage conditions
Water left inside a heater can be a concern when temperatures drop. One CAMPLUX model lists an anti-freezing drain plug, but that feature does not replace following the manufacturer’s storage instructions. Drain and store the unit as directed, and check each model’s guidance for cold-weather use before taking it on a freezing-weather trip.
Frequently Asked Questions
Can I use a portable propane tankless water heater inside a tent or camper?
These products are described as outdoor heaters. Do not operate one inside a tent, vehicle, camper, or other enclosed space. Follow the manufacturer’s safety instructions and use the heater only in an appropriate outdoor setting.
Do these heaters need electricity?
Some of the listed models use batteries for ignition rather than a household electrical connection. The CAMPLUX 5L and the two Amzgachfktch 6L heaters specify two D-cell batteries. Check the instructions for the model you choose, since the supplied details do not state the ignition power source for every product.
Will a gravity-fed water bag work?
It depends on the heater and the pressure the water source can provide. The CAMPLUX 5L listing describes use with a gravity water bag and specifies a 3.0 PSI starting pressure. The Amzgachfktch 6L models specify 2.5 PSI. Compare the heater’s minimum pressure with your setup before relying on gravity feed.
Which model is easiest to carry?
The CAMPLUX 5L is the lightest listed option at 10 pounds. The two Amzgachfktch 6L heaters weigh 12 pounds, the CAMPLUX 2.64 GPM heater with pump pack weighs 15 pounds, and the other CAMPLUX 2.64 GPM model weighs 23 pounds.
What does GPM mean for a camping water heater?
GPM means gallons per minute and describes the heater’s listed water flow rate. A higher maximum rating can be useful for some tasks, but it does not guarantee the same result in every setup. Water pressure and incoming water temperature also affect how the heater works.
Do all five heaters include a pump?
No. The CAMPLUX 2.64 GPM model with pump pack specifically includes a 3.3 GPM pump kit. The other supplied product descriptions list different accessories, but do not identify an included pump. Check the package details before ordering if your water source needs one.
Final Recommendation
For a convenient camp shower setup with a pump included, the CAMPLUX 2.64 GPM heater with pump pack is the most complete choice in this group. If low weight matters most, the 10-pound CAMPLUX 5L is the easiest to carry, though its listed flow rate is lower. Campers who want a higher-flow heater and can handle more weight may prefer the 23-pound CAMPLUX 2.64 GPM model. Before choosing, confirm that your water pressure, propane supply, and planned outdoor setup match the product’s requirements.
