Propane Tankless Water Heater 2.64GPM Instant Hot Water - Portable

Our review of the GASLAND Outdoors Propane Tankless Water Heater finds it best suited to campers, RV owners and cabin users who need instant hot water from a portable unit. The single biggest reason to buy is its strong heat output and low-start requirement: it delivers up to 2.64 GPM with a maximum 68,000 BTU/hr, and it will fire at just 3.6 PSI of water pressure, making reliable hot showers possible in remote or low-pressure situations.

Key Features

• Flow and Power: Delivers up to 2.64 gallons per minute and a maximum power output of 68,000 BTU/hr, which produces rapid temperature rise for short hot-water needs.
• Temperature Rise: Capable of raising water temperature up to about 109.4F (43C) at higher inlet temps and still providing 55.4F (13C) rise at full 2.64 GPM flow, useful for quick warm showers.
• Low Pressure Start: Starts with only 3.6 PSI of water pressure, so it works in many RV plumbing and campsite setups where pressure is limited.
• Portable LPG Powered: Runs on a standard 20 lb. liquid propane tank with electronic ignition powered by two D-cell batteries, which suits off-grid and outdoor use.
• Included Accessories: Ships with a CSA certified gas regulator and hose, an on/off switch shower head, mounting hardware and a garden hose adapter for straightforward setup.
• Safety Tip: Designed for outdoor use with overheating protection, but the manufacturer warns not to use Teflon tape on the gas regulator connection and to check for leaks before each use.

Who It's For

The GASLAND propane tankless heater is aimed at people who need a portable, high-output solution: RV owners, cabin dwellers, campers and those with outdoor showers or temporary washing needs will appreciate the instant hot water and low-pressure start. It is also a practical choice for users who need a quick heat source for pet washing, vehicle cleaning or a tiny home with intermittent hot-water demands.

This is not ideal for full-time indoor household replacement or installations requiring horizontal mounting, since the unit is intended to be mounted vertically and is designed for portable outdoor use; prolonged exposure to rain or indoor permanent installations may shorten its life. Those seeking a sealed, long-term indoor solution should look at dedicated indoor-certified tankless models.

Pros & Cons

Pros

• Strong heating capacity for a portable unit, producing usable hot water quickly.
• Low water pressure start makes it compatible with many campsite and RV plumbing systems.
• Comes with regulator, hose and shower head for fast setup right out of the box.
• Runs on a common 20 lb. LPG cylinder and uses simple battery ignition for off-grid use.

Cons

• Customers report durability and leakage problems, with some units failing within months under light use, so longevity may be inconsistent.
• Not rated for horizontal installation and prolonged exposure to wet conditions can damage internal components.

Our Verdict

For weekenders, RV travelers and cabin users who need fast, portable hot water, this propane tankless heater is a strong value: it heats quickly, starts at very low pressure and comes with the accessories needed for outdoor setup. However, durability concerns and sensitivity to prolonged wet exposure mean buyers should expect a product best used seasonally or with careful storage and maintenance.
