Tankless Water Heater Propane 3.18GPM 12L Outdoor Portable Heater

Our review of this tankless propane water heater finds it best suited for campers, van lifers, and off-grid cabins who want reliable on-demand hot water without a tank. The single biggest reason to buy is its portability paired with a complete accessory kit: the unit ships with a CSA-approved gas regulator, a 2GPM 12V water pump with dual power leads, shower and pet heads, and hoses so it is ready to use at a campsite. It delivers up to 3.18 gallons per minute with a substantial max temperature rise for quick hot showers away from home.

Key Features

• Portable design: Compact dimensions and folding handles make it easy to carry and position at an outdoor shower or grid cabin.
• Complete accessory kit: Included CSA-approved 5ft gas regulator, pump, multiple hoses and showerheads eliminate the need to source extra parts before use.
• High flow and heat: Delivers approximately 3.18 GPM and a maximum temperature rise sufficient for hot showers even in cool conditions.
• Safety protections: Built-in flame failure device, anti-freeze protection and overheating protection add peace of mind when used outdoors.
• Efficient combustion: Advanced burner and heat exchanger design reduce gas consumption and noise while providing up to 68,000 BTU/hour of power.
• Flexible pump power: The 2GPM water pump accepts alligator clips or cigarette lighter power for use from a vehicle or battery source.

Who It's For

This unit is aimed at outdoor enthusiasts who need a portable, ready-to-use hot water solution: campers who want an instant shower after a long hike, van dwellers who need compact gear, and small off-grid cabins lacking a plumbed water heater will find the package convenient. The included pet showerhead also makes it a good choice for owners who want to wash dogs on location.

It is not intended for indoor installations or use with natural gas; this model runs on propane (LPG) only and requires proper outdoor ventilation. Buyers who need a high-volume household system or an indoor, code-installed heater should look for larger, permanently installed units designed for indoor plumbing.
