Overview

The Gasland BS158 is a portable propane outdoor water heater rated at 1.58 gallons per minute and 41,000 BTU per hour, running on a standard 20 pound propane tank with battery ignition for use away from any electrical or gas line hookup.

  • 1.58 GPM, 41,000 BTU/hr propane water heater
  • Runs on a standard 20 lb propane tank
  • Starts at just 3.6 PSI water pressure
  • CSA certified with overheat and flame failure protection

Who it's for

Suits outdoor showers, stock-tank pools, camping, and off-grid cabins where there is no fixed water heater, particularly for buyers who plan to use it repeatedly across seasons rather than once. Not intended for high-altitude sites above 3300 feet or persistently windy locations.

What buyers say

From Amazon customer reviews.

Long-term buyers, some running multiple units across several years of outdoor showers, describe it as reliable and credit Gasland's customer service by name for resolving ignition failures and other hardware problems quickly with replacements. The main complaint is inconsistent temperature, with one buyer reporting the heat swinging from scorching to lukewarm without touching the controls, and another received a unit with a visibly damaged exhaust port from shipping. A couple of buyers also found the hose fitting design awkward to store between uses compared to an older, discontinued unit they had used before.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Runs off a standard propane tank, no electricity needed
  • Low 3.6 PSI startup works off a garden hose
  • Comes with shower head, hose, and regulator included
  • Company has replaced failed units and parts under warranty
What to check first
  • Temperature can fluctuate without the controls being touched
  • Not rated for high altitude or strong wind
  • One buyer's unit arrived with a smashed exhaust port
  • Hose fitting design makes storage awkward between uses

Performance notes

The unit ignites off two D batteries once the propane and water lines are running, and its low 3.6 PSI startup threshold means it can run directly off a garden hose without a booster pump in most home setups. Most reviewers who used it across multiple seasons report consistent heat, though a minority describe the temperature fluctuating on its own without the knobs being touched, and Gasland's stated limits on altitude and wind point to where the flame control can struggle.
