Gasland BE158S 1.58 GPM Propane Tankless Water Heater - Portable

In this review of the Gasland BE158S tankless water heater, the bottom line is simple: it is a compact, portable solution for people who need on-demand hot water off the grid. Designed to run on a standard 20 lb. liquid propane tank with battery-powered electronic ignition, the BE158S delivers a steady 1.58 GPM and up to 41,000 BTU/hr, making it a practical choice for camping, van life, hunting camps, or small cabins where mains electricity is unavailable or undesirable.

Key Features

• 1.58 GPM Flow: Produces about 1.58 gallons of hot water per minute, enough for quick outdoor showers and basic washing tasks.
• High Heat Output: Maximum 41,000 BTU/hr output lets the unit raise water temperature substantially, with a listed maximum raise of about 109.4F at low inlet temperatures.
• Low Water Pressure Start: Starts at just 3.6 PSI, which helps the unit run with weaker supply lines common at rural sites and portable setups.
• Battery Electronic Ignition: Runs on two D-cell batteries so no AC power is required, making it suitable for off-grid use with a 20 lb. propane tank.
• CSA Certified Safety: Includes multiple protections such as over-heating, low water flow, dry combustion, anti-freezing and flame failure device for safer outdoor operation.
• Included Accessories: Ships with a CSA certified regulator and hose, on/off shower head, mounting hardware, and garden hose adapter for straightforward setup.

Who It's For

The BE158S is aimed at outdoor enthusiasts who need reliable hot water without mains power: campers, van lifers, hunters at base camp, tiny home or cabin owners, and people who want a portable shower or washing station for animals and vehicles. Its portability and propane operation make it especially useful where electricity is limited or absent.

This is not intended as a full household replacement for families with high hot water demand; the modest 1.58 GPM flow and portable design mean it performs best for single-point uses rather than multiple simultaneous fixtures. Buyers needing strong pressure for full indoor plumbing should consider a larger, plumbed-in system.

Pros & Cons

Pros

• Portable propane operation and battery ignition enable true off-grid use.
• Strong maximum heat output provides rapid temperature rise for quick hot water.
• Low start pressure and included fittings make setup easier in remote sites.
• Comprehensive safety protections and CSA certification add confidence for outdoor use.

Cons

• Flow rate and delivered water pressure are modest, so it is best for single-user tasks rather than full indoor systems.
• Some customers report issues with hose durability and lower-than-expected pressure from supplied hoses, so upgrading hoses may be necessary.

Our Verdict

The Gasland BE158S is a practical, value-minded choice for consumers who need portable, on-demand hot water away from mains power. It combines a respectable 41,000 BTU output, battery ignition, and safety features in a compact package. For single-point outdoor showers, vehicle cleaning or campsite use it represents good value, though those who need higher flow or more durable supplied hoses should budget for minor upgrades.

Frequently Asked Questions

Can this run without household electricity?
Yes. The BE158S uses two D-cell batteries for electronic ignition and runs on a standard 20 lb. liquid propane tank, so no AC power is required.

Is it safe for outdoor use in cold weather?
It includes anti-freezing protection, but the manufacturer recommends draining and storing the unit indoors in winter to avoid damage from prolonged freezing conditions.

Will it provide enough pressure for a shower?
It starts at low pressure (3.6 PSI) and can heat at 1.58 GPM, which is suitable for quick outdoor showers; however, supplied hose strength and overall pressure are modest, and some users replace the hose for better durability and flow.
