Propane space heaters deliver fast, reliable heat for garages, workshops, construction sites, patios, RVs, and backup during power outages. They fire up quickly, perform well in sub-zero temps, and don’t rely on grid power, making them a practical choice for portable heat and spot heating.

Popular types include radiant (quiet, focused warmth), forced-air/torpedo (high-BTU jobsite blasting), convection (360-degree heat), and catalytic (low-odor, low-CO output). Choose BTU output to match space size: about 20–40 BTU per square foot for uninsulated areas, 15–25 for insulated.

For indoor use, look for vent-free units approved for indoor spaces with an oxygen depletion sensor (ODS), tip-over switch, overheat protection, and low-oxygen shutoff. Always follow ventilation guidelines and local codes. For enclosed, continuous heating, consider vented wall or garage heaters with direct-vent kits.

Common fuel sources are 1 lb cylinders for portable heaters and 20 lb or larger DOT tanks for longer runtimes. A 20 lb tank stores roughly 430,000 BTU; a 30,000 BTU/hr heater runs about 14 hours on high (430,000 ÷ 30,000). Use quality regulators and hoses rated for propane.

Useful features include thermostat control, variable heat settings, piezo or electronic ignition, low-pressure operation, quiet fans, and high-altitude compatibility. Look for CSA or UL listings and clearances printed on the nameplate. If noise matters, pick radiant or catalytic; if fast warm-up is key, go forced-air.

Operate on a stable, level surface away from combustibles. Keep clearances as specified. Never sleep with an unvented heater running. Install a CO alarm, crack a window for indoor-safe models, and check for leaks with soapy water after connecting. Store cylinders upright outdoors, out of direct sun.

Choose BTU to fit space and insulation, verify indoor or outdoor rating, plan runtime and fuel, and confirm accessories. The right propane heater delivers reliable heat wherever you work, relax, or camp.
