What is the best camping water heater for your setup?

To help you choose, we have objectively compared 4 flagship solutions available on our e-shop:

1. the Camplux Nano 3 Max
2. the Kampa Geyser 
3. the RinseKit HyperHeater 2.0
4. the RinseKit PRO with its immersion heater

Because every van conversion is unique, we have gathered all essential data in a comparison table at the end of this article. We hope this overview will help you precisely target the portable water heater that meets your road trip needs. 

The Camplux Nano 3 Max is the major new exclusive to arrive on the European market. This instant, tankless gas water heater is shaking up vanlife standards. It provides hot water on demand thanks to a powerful gas burner (butane/propane), while its electronics, water pump, and LED control screen are powered 100% autonomously by an integrated lithium battery.

Strengths of the Camplux Nano 3 Max

• 100% Wireless Technology: Thanks to its integrated 4,000 mAh battery, this model eliminates cables. No need to plug it into your van's 12V cigarette lighter or a power station during use. It offers between 100 and 150 minutes of pure autonomy for showering anywhere.

• Thermal comfort and high flow rate: It boasts unprecedented performance for a portable model with a nominal flow rate of up to 10 liters per minute. The touch screen allows you to adjust the temperature to the nearest degree for a stable shower, with pressure similar to home.

• Safety and complete kit: It integrates advanced safety sensors (automatic shut-off in case of overheating or lack of water). The "Max" version comes as a premium pack with a carrying bag, charging adapters (220V and 12V), and a versatile showerhead (ideal for returning from the beach or for pets).

Limitations of the Camplux Nano 3 Max

• Purchase price: This is the most high-end and expensive model.

• Weight and dimensions: With a weight of over 6 kg and a generous size, it requires dedicated storage space in small converted vans.

The Kampa Geyser portable water heater is a true institution in the world of wild camping and converted vehicles. Unlike recent battery-powered systems, this model relies on a traditional, ultra-reliable technology praised for its robustness. It requires a continuous 12V power supply to operate its submersible pump (included), while instant water heating (between 30°C and 55°C) is provided by a gas burner to be connected to a butane or propane bottle.

Strengths of the Kampa Geyser

• Excellent value for money: This is its number one asset. For an affordable budget of around €240, it allows you to have instant hot water on road trips without breaking the bank.

• Versatility of use (Cold water option): A switch allows you to turn off the burner to use only the pump. Practical for saving gas when you simply need cold pressurized water (washing dishes, rinsing bikes or sports equipment).

• Temperature management: Two knobs on the front allow manual adjustment of water flow and gas intensity (up to +25°C increase compared to the initial water temperature). A digital display allows real-time temperature monitoring.

• Robust and portable format: Housed in a rigid steel chassis with a handle, it comes with a practical compartmentalized carrying bag for storing the device, hoses, and showerhead.

Limitations of the Kampa Geyser

• 12V electrical dependence: Lacking an internal battery, it must remain plugged into your vehicle's cigarette lighter socket or a portable battery during use.

• Moderate water flow: Its flow rate of approximately 2.5 liters per minute is very economical for preserving your water reserves, but offers less pressure for rinsing long hair, for example, or for washing or rinsing sports equipment.

The RinseKit HyperHeater 2.0 water heater adopts a radically different philosophy. Designed by the leader in portable showers, this compact system does not include a classic water pump. It connects directly to the brand's rigid pressurized tanks (such as the RinseKit Cube model or the PRO Pack with battery and immersion heater).

The HyperHeater uses small standard propane gas cartridges to instantly heat water propelled by the tank's natural pressure.

Strengths of the RinseKit HyperHeater 2.0

• The best pressure on the outdoor market: By leveraging RinseKit's pressurized tank technology, this combo delivers a powerful and consistent jet. It is the ideal solution for removing ingrained mud, rinsing diving equipment, or thick hair.

• Record heating speed: Water reaches its maximum temperature (up to 49°C) in less than 30 seconds flat, with very intuitive adjustment via a single dial on the front.

• Compactness and modularity: The water heater housing is extremely compact and lightweight. It clips in series in seconds to your existing RinseKit shower thanks to quick-connect fittings (Quick-Connect).

• Onboard safety: Equipped with an LED control panel, it integrates an automatic circuit breaker if the water exceeds the maximum allowed temperature.

Limitations of the RinseKit HyperHeater 2.0

• Dependence on the brand's ecosystem: The HyperHeater 2.0 cannot operate alone with a simple bucket of water. It absolutely requires a RinseKit standalone shower. 

• Gas cartridge format: It mainly works with small threaded disposable propane bottles. While compact, this requires anticipating consumable stocks for long journeys.

For travelers seeking an all-in-one solution without the hassle of an external gas water heater, the RinseKit PRO portable and autonomous shower combined with its 12V immersion heater offers an excellent alternative. This rigid 13.3-liter tank integrates its own battery to generate constant and powerful pressure on demand.

To get hot water, simply attach the RinseKit immersion heater: this electric heating element screws directly inside the tank and plugs into your vehicle's 12V cigarette lighter socket.

Strengths of the RinseKit PRO + Immersion Heater formula

• Zero gas consumables: This system runs 100% on your vehicle's electricity. This is ideal if you don't want to handle or store gas cartridges (propane/butane) in your van.

• Smart heating while driving: You can plug in the immersion heater during your travel time. The water gradually heats up as you drive, allowing you to have a nice hot shower as soon as you turn off the engine to bivouac.

• Maximum compactness: No additional equipment to install or hang outside. Everything happens inside the RinseKit PRO cube, making it the most compact and clean solution for small spaces.

Limitations of this configuration

• Progressive heating time: Unlike instant gas systems (like Camplux or HyperHeater) that heat water in seconds, the immersion heater requires anticipation (allow about 1 to 1.5 hours to bring the entire tank to an ideal shower temperature). Additionally, water heats faster when in motion.

• Power consumption: Resistance heating in 12V is energy-intensive. It is therefore strongly recommended to use it only when the vehicle engine is running or if you have a high-capacity portable power station.
