Eccotemp L5 Portable Tankless Water Heater
The Eccotemp L5 is a time-tested favorite for campers and off-grid adventurers who need hot water on demand. This compact propane tankless heater delivers up to 1.5 gallons per minute of hot water, making it ideal for outdoor showers, dishwashing, and pet cleaning. It runs on standard propane (attachable to a 20 lb grill tank) and uses two D-cell batteries for automatic ignition, so no electricity is required. At roughly 11.5 pounds and with a slim profile, the L5 is highly portable – you can hang it on a tree, RV exterior, or a sturdy post using its built-in handle.
Despite its small size, the Eccotemp L5 packs a punch with a 37,500 BTU burner, which can raise water temperature by about 30–40°F (depending on flow rate and input water temp). It features simple controls: one knob for burner flame and one for water flow, allowing you to adjust the temperature output. In terms of safety, the L5 has an automatic 20-minute shutoff timer to prevent overheating and a tilt sensor that shuts off gas if the unit is tilted too far. This heater is straightforward to set up: just connect the propane, attach a garden hose or 12V pump-fed water source, and it ignites automatically when you turn on the water flow.
Pros:
• Lightweight and compact: Easy to carry and mount at campsite.
• Fast hot water: Provides instant hot water for showers or washing.
• Easy setup: Simple hookup to propane and water; no tools for ignition.
• Reliable performance: Well-proven design with many years on the market.
Cons:
• Requires water pressure source: Needs a pressurized water supply (hose hookup or separate pump) to activate.
• Outdoor use only: Lacks an oxygen sensor, so it must be used in well-ventilated areas (not safe for indoor use).
• Safety shutoff timer: Auto shuts off after 20 minutes continuously, which is a safety feature but means you must restart for longer showers.
• Not ideal for high altitudes: Performance can suffer or shut off at elevations above ~5000 feet due to thinner air for combustion.
The Eccotemp L5 remains one of the best overall choices for portable hot water thanks to its balance of portability, sufficient flow, and affordability. It’s a great fit for campers who want a reliable shower unit without breaking the bank.
Camplux 2.64 GPM (10L) Outdoor Tankless Water Heater
For those needing a higher volume of hot water or serving multiple outlets at once, the Camplux 2.64 GPM Tankless Water Heater stands out with its superior flow rate. Often referred to by its “10L” capacity class, this propane tankless heater can deliver up to 2.64 gallons per minute – enough to support an outdoor shower and sink simultaneously or to simply enjoy a stronger shower stream. It outputs roughly 68,000 BTUs of heat, providing a bigger temperature rise suitable for cooler incoming water or heavier usage. Despite the higher output, the unit is still portable at around 18 pounds, though it is bulkier than smaller 5L heaters. It features a folding carry handle and can be mounted on a hook or screwed to a post for semi-permanent setups.
The Camplux heater uses two D-cell batteries for ignition and starts up automatically when water flows through. It includes convenient safety features like a flame failure shutoff, overheating protection, and an oxygen depletion sensor (ODS) that will turn off the burner if oxygen is low (important if you ever use it in a semi-enclosed area, though it’s intended for outdoor use). The front panel has gas and water flow knobs, plus an LED temperature display for monitoring output temperature. This model shines for basecamp setups, cabins, or off-grid homes where you want an on-demand hot water source that’s more robust than the smaller camp shower units.
Pros:
• High flow rate: 2.6 GPM can handle multiple tasks or a higher-pressure shower.
• Strong heating power: 68,000 BTU burner heats water quickly, suitable for cooler climates or larger volumes.
• Safety features: Equipped with ODS sensor, overheat protection, and flame-out shutoff for safe operation.
• Rugged build: Sturdy construction can be mounted for semi-permanent use (great for outdoor shower setups).
Cons:
• Less portable: Bulkier and heavier than standard portable units, making it a bit less convenient to move frequently.
• Propane usage: Higher BTU output will consume propane faster (best paired with a large propane tank).
In summary, the Camplux 2.64 GPM is an excellent choice for those who need extra hot water capacity outdoors. It’s particularly well-suited for off-grid cabins, horse washing stations, or deluxe camp shower setups where a regular small camp heater might not keep up.
Gasland BE158 Portable Tankless Water Heater
The Gasland BE158 is another popular propane tankless water heater tailored for camping, RV showering, and other outdoor uses. It’s in the same class as the Eccotemp and Camplux small units, with a rated output of 1.58 GPM (roughly 6 liters) of hot water flow. The Gasland stands out by offering slightly higher heat output (around 41,000 BTU) and a digital temperature readout, all while maintaining a compact, lightweight design (~15 pounds). Like its competitors, it fires up with 2 D-cell batteries and features automatic ignition when water flows through the unit.
This heater is easy to carry thanks to its folding handle, and setup takes just a few minutes – connect the gas hose to a propane tank, attach the included shower head and hose, and feed the inlet either from a garden hose or a 12V pump drawing water from a bucket or stream. The Gasland BE158 includes multiple safety protections: flame failure and anti-dry-burning shutoff (it will cut gas if the flame goes out or if water supply is too low), overheat protection to prevent scalding, and even freeze protection (a drain plug to empty water after use, so the exchanger doesn’t crack in cold weather). It’s also CSA certified for safety. The unit works best with moderate water pressure; it has a built-in sensor requiring a minimum flow/pressure to activate, which is standard for these tankless designs.
Pros:
• Excellent value: Generally priced affordably while delivering performance on par with more established brands.
• Compact design: Easy to carry and stow, with a slim profile for packing in an RV or car trunk.
• Safety and protection: Offers comprehensive safety features (overheat, flameout, pressure protection) for peace of mind.
• Quick hot water: Heats up fast and provides steady temperature for showers or cleaning.
Cons:
• Requires pressurized water source: Like similar tankless units, it won’t turn on without sufficient water flow (may need a separate pump off-grid).
• Outdoor-only use: Must be used in open air; not for indoor or tight enclosure use due to carbon monoxide risk (no internal ODS sensor).
• Elevation sensitivity: May struggle or shut off at high elevations (mountain camps) where thinner air affects propane combustion.
• Shower attachment is basic: The included shower head is functional but not fancy – some users upgrade to a higher-quality sprayer.
The Gasland BE158 is a solid contender in the portable water heater market, offering hot showers and washing capability at a budget-friendly price. It’s a great pick for campers and RVers who want reliable hot water but don’t need the bells and whistles of more expensive systems.
Joolca HOTTAP Nomad Kit (Portable Hot Shower System)
If you’re looking for a premium all-in-one camp shower setup, the Joolca HOTTAP V2 Nomad Kit is often considered the gold standard – albeit at a much higher price. Joolca’s system is a portable propane tankless water heater like the others, but it comes as a complete kit with high-quality accessories and is built with an eye toward durability and ease of use. The heater unit itself provides up to 1.6 GPM of flow and about 37,500 BTU of heating power, putting its performance on par with units like the Eccotemp L5. What sets Joolca apart is the Nomad kit includes everything you need: a 12V water pump with quick-connect hoses and filter (so you can draw water from a jerry can or stream), a shower head with various spray settings, a smart faucet attachment for washing dishes, a gas hose and regulator, and even a carrying bag that neatly fits the whole system.
Setting up the Joolca HOTTAP is straightforward. You connect the color-coded quick-connect hoses, drop the pump in your water source, connect to a propane tank, and power the pump via a 12V socket (from a vehicle or battery pack). The water heater ignites with two D-cell batteries and has simple controls to adjust temperature. One appreciated feature is the ability to fine-tune water temperature by adjusting both gas and water flow, ensuring you don’t get scalded. The system can deliver comfortably hot showers (temperature adjustable up to around 120°F depending on input water) and the shower head has an integrated on/off trigger to conserve water. The build is rugged – the heater has a metal body and Joolca has a reputation for designing for harsh Australian outback conditions (where the company originated).
Pros:
• Complete kit: Comes with a pump, shower, sink faucet attachment, and all hoses – you have everything needed for a portable hot shower and camp kitchen.
• Easy to use: Quick-connect fittings and thoughtful design make setup and teardown fast (no complicated assembly each time).
• Durable and well-built: Quality components built to last, with a sturdy metal heater unit and reliable pump.
• Versatile: Can draw water from any source (bucket, river, etc.) with the included pump and filter; great for truly off-grid use.
Cons:
• Very expensive: Significantly higher cost than DIY solutions or other brands – you pay a premium for the convenience and quality.
• Requires 12V power for pump: While the heater ignition is battery-powered, the water pump needs a 12V DC source (vehicle outlet or portable battery), adding a dependency.
• Bulky kit: With all components, it takes up space – the carry bag helps, but it’s a sizable package to transport.
• Not significantly hotter than cheaper units: The max water temperature and flow are similar to less expensive heaters (the premium is mostly for the accessories and build quality).
For overlanders, glampers, or off-grid families who want a top-of-the-line solution and are willing to invest, the Joolca HOTTAP Nomad Kit delivers a luxurious outdoor hot water experience. It’s ideal for extended camping setups where convenience and reliability justify the cost.
BougeRV Portable Propane Water Heater (Battery-Powered Unit)
BougeRV’s Portable Propane Water Heater is one of the new-generation models that integrate a water pump and rechargeable battery into a single compact unit. This all-in-one design is perfect for truly mobile hot water needs – you don’t need an external power source or separate pump, just the heater itself, a propane canister, and a source of water. The BougeRV heater is a cube-shaped unit (about 15.7″ x 12.2″ x 6.7″) with a built-in handle, weighing roughly 14 pounds. Inside, it houses a 2500 mAh lithium battery that powers the electronic ignition and an integrated pump capable of drawing water from a bucket or lake. You can get around 40-60 minutes of continuous hot water on a full battery charge. It also offers multiple charging options: you can recharge or even run it via a car’s 12V outlet, a portable power station, or AC power at home, thanks to included adapters.
In terms of performance, the BougeRV unit provides about 1.1 to 1.2 GPM of flow through its showerhead – enough for a decent camp shower or washing dishes. Its burner outputs around 20,000 BTU, heating water by roughly 30–45°F above the source water temperature. Users can set their desired temperature on a digital control panel (it ranges roughly from 104°F up to 122°F max). The device has intelligent safety features: it will automatically shut off if the water temperature exceeds a safe limit (about 122°F), if the unit is tilted too much or knocked over, or if water flow stops for more than a couple of minutes (to prevent dry burning). The showerhead nozzle has an on/off trigger and adjustable spray pattern, and the kit includes a siphon hose with a filter to drop into your water source.
Pros:
• Self-contained system: Built-in battery and pump mean you can have hot water anywhere with no external power or pressurized water hookup needed. Truly plug-and-play for off-grid.
• Digital controls: Easy to adjust temperature with an LCD display; unit maintains consistent output temperature once set.
• Multiple power options: Use the internal battery or plug into 12V/AC if available – very flexible in the field or at home.
• Safety shutoffs: Auto stop for overheat, low water, or tip-over adds peace of mind during use.
Cons:
• Higher cost: Considerably more expensive than basic tankless heaters due to the added tech (battery, pump, electronics).
• Heavier than basic units: The internal components add weight; not as lightweight as a simple heater coil unit, though still manageable.
• Battery maintenance: You need to remember to charge the battery, and over time battery capacity will diminish (it’s replaceable but an added upkeep factor).
• Limited flow compared to larger heaters: The flow and pressure are decent but not as strong as a higher-BTU tankless hooked to a garden hose. It’s optimized for one shower or task at a time.
The BougeRV Portable Heater is an excellent solution for campers, overlanders, or tiny home dwellers who want a truly off-grid hot water system with minimal setup. It’s on the pricier side, but the convenience of just flipping a switch for instant hot water anywhere can be well worth it.
Hike Crew Portable Propane Water Heater (with Battery and Pump)
Another newcomer in the all-in-one category is the Hike Crew Portable Propane Water Heater and Shower System. Similar in concept to the BougeRV, the Hike Crew combines a propane water heater with a built-in pump and rechargeable battery, packaged in a convenient carrying case. This unit is designed to heat water up to about 125°F, providing a warm shower or cleaning water wherever you roam. It includes a pump that can draw from any fresh water source and a rechargeable battery that yields roughly 50 minutes of continuous run time per charge. The system comes with a removable showerhead on a hose, a propane hose for 1 lb cylinders (or adaptors for larger tanks), and even a faucet attachment that mounts on the unit for hand-washing or filling containers.
The Hike Crew heater offers adjustable settings via an LCD display and buttons, letting you set your target temperature. It will automatically ignite the propane burner and start the pump when you open the faucet or shower head. Safety features are built-in: an automatic shutoff kicks in if the water gets too hot or if the unit runs dry, and a tilt sensor will cut the flame if the device tips over. The carry case and frame not only protect the unit but also make it easier to transport (though it is somewhat bulky, around 15 pounds). This model is often praised for its convenience in campsites and outdoor events, where you might be far from utilities.
Pros:
• All-in-one convenience: Integrated battery and pump system – just add water and propane and you have hot water ready to go.
• User-friendly interface: The digital display and simple controls make it straightforward to operate and monitor temperature.
• Safety and auto-shutoff: Overheat protection and tip-over shutoff ensure safe usage in varied environments.
• Versatile usage: Great for camping showers, outdoor dishwashing, pet cleaning, and even emergency preparedness (hot water during power outages).
Cons:
• Bulky form factor: The unit with its case is larger to carry around compared to slim tankless heaters; may take up considerable space in your vehicle.
• Moderate flow rate: The pump provides a usable shower stream, but it’s not as strong as a higher-powered tankless connected to a pressurized hose.
• Battery dependency: If you forget to charge it or don’t have a way to recharge in the field, you’re limited (though you can run it off 12V or AC with the adapters).
• Build mostly plastic: While sturdy enough for normal use, it’s not as rugged metal as some other heaters; care is needed to avoid drops or rough handling.
Overall, the Hike Crew Portable Water Heater offers a fantastic blend of mobility and comfort for outdoor enthusiasts. It’s slightly more affordable than similar all-in-one competitors while still delivering the core benefits of hot water anywhere. This makes it a compelling choice for campers who want convenience but are watching their budget.
Choosing the Right Portable Water Heater for Your Needs
Each of these portable water heaters brings something unique to the table, so the “best” choice depends on your specific outdoor needs:
• For simple camping showers and budget-conscious buyers: Basic tankless units like the Eccotemp L5, Camplux 5L, or Gasland BE158 are ideal. They’re lightweight, easy to use, and provide ample hot water for showering and washing up at camp, all without a high cost. Just remember you’ll need a water source with some pressure (or a small 12V pump) to feed the heater.
• For higher demand and semi-permanent setups: A more powerful unit such as the Camplux 2.64 GPM (10L) or similar high-output models (including the 2.64 GPM versions by Flame King or Eccotemp) will serve better. These can handle multiple uses at once (e.g., an outdoor kitchen and shower) and perform well in cooler weather or for larger groups.
• For premium convenience: If you want a turnkey solution with all accessories and top-notch build quality – and don’t mind the premium price – the Joolca HOTTAP Nomad Kit is a luxury choice. It’s best for frequent campers, overlanders, or off-grid dwellers who will use the system often and appreciate its durability and completeness.
• For off-grid versatility: New all-in-one systems like the BougeRV Portable Heater and Hike Crew Portable Heatershine in situations where you have no running water or external power. They’re self-sufficient units perfect for remote cabins, dispersed camping, or emergency use. BougeRV offers a bit more tech and polish (at a higher price), while Hike Crew provides similar functionality at a slightly lower cost.
No matter which unit you choose, always prioritize safety and proper usage. Only operate these propane heaters outdoors or in very well-ventilated areas to avoid carbon monoxide buildup. Keep the unit away from flammable materials, and secure it so it won’t tip over during operation. Regular maintenance – such as cleaning filters, draining water after use, and checking propane connections – will ensure your portable water heater remains reliable for many adventures to come.
