Overview

The GASLAND Flame Jet is a forced air propane heater with adjustable output from 75,000 to 125,000 BTU, rated to warm spaces up to 3,100 square feet. It connects to a standard 20 lb propane tank with the included 10 ft hose and regulator, giving roughly 5 hours of runtime on its low setting.

This is a job site and workshop heater rather than a living space heater, built around a steel housing and a burner that adjusts across a wide BTU range instead of fixed settings. Continuous electronic ignition lights the burner without a pilot light, and a thermo-electric safety valve cuts gas flow if the flame goes out. GASLAND markets it for well ventilated spaces like garages, barns and construction sites, not sealed rooms.

Who it's for

Pros and cons

Pros
  • Adjustable 75,000 to 125,000 BTU output
  • Covers large spaces up to 3,100 sq ft
  • Includes 10 ft hose and regulator
  • CSA certified with overheat and flame out shutoff
Cons
  • Built for ventilated spaces, not sealed rooms
  • About 5 hours runtime per 20 lb tank
  • Steel build adds bulk versus small heaters

Performance notes

Forced air propane heaters push heated air out with a fan rather than relying on convection, which is why this unit can cover up to 3,100 square feet versus the roughly 500 square feet of a small ventless indoor heater. The adjustable 75,000 to 125,000 BTU range lets output be tuned down for smaller areas or lower fuel use, and on a standard 20 lb tank the low setting runs for about 5 hours before a refill. The thermo-electric safety valve and overheat detection shut gas flow off if the flame drops out or the unit runs too hot.
