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.
Pros and cons
- 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
- 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.
