Propane Heaters for Garages, Jobsites, and Patios

Instant Heat With No Fuel Storage Hassle

Propane heaters light at the push of a button and reach full output in seconds, with none of the priming or warm-up a liquid-fuel heater needs. They run off the same 20-pound and 100-pound cylinders most crews already keep on hand, and propane stores indefinitely without going stale the way gasoline or kerosene can. The trade-off is fuel logistics on long jobs: a high-BTU forced-air unit will drain a 20-pound tank quickly, so match the cylinder size to the run time.

Forced-Air, Radiant, Cabinet, and Convection

Propane forced-air models throw a heated air stream to warm a whole garage or open bay fast. Radiant tank-top heaters mount on the cylinder itself and aim directional heat where a worker stands, with no electricity required. Cabinet heaters give quiet, portable warmth for a smaller enclosed area, and convection heaters push heat outward in 360 degrees for the middle of a large floor. Every model burns fuel, so ventilation and a carbon-monoxide detector are required indoors; see the CDC carbon monoxide guidance.

Pick the Model for Your Space

Open construction floor or garage: a forced-air unit. Outdoor crew or spot heat with no power: a radiant tank-top. Patio or event space: a standing radiant patio heater. Center of a warehouse: convection. Related: Portable Heaters · Forced Air Heaters · Kerosene Heaters. For a mid-size garage, the MH-0150 propane forced-air heater covers about 3,800 square feet.

Frequently Asked Questions

How long does a 20 lb propane tank last on a heater?
Runtime depends on BTU draw. A 15,000 BTU tank-top heater runs about 28 hours on high from a 20-pound cylinder; a 150,000 BTU forced-air unit drains the same tank in a few hours, so high-output models pair better with a 100-pound tank.
Are propane heaters safe indoors?
Only with adequate ventilation and a carbon-monoxide detector. Propane burns cleaner than kerosene but still consumes oxygen and produces exhaust; never run one in a sealed room without fresh-air makeup.
Do propane radiant heaters need electricity?
No. Radiant tank-top heaters mount on the cylinder and light by match or piezo igniter, so they work on open sites and outdoors with no power source.
What size propane heater for a 1,500 sq ft garage?
A 60,000 BTU propane forced-air heater covers roughly 1,500 square feet of average-insulated garage. Step up to 150,000 BTU for high ceilings, poor insulation, or faster warm-up.
