The Dura Heat GFA60A offers a 30,000–60,000 BTU variable output and is a simple propane forced-air heater intended for garages and job-site spaces. It operates between 7–14 hours on a 20 lb cylinder depending on settings.

Designed for straightforward operation, this model emphasizes ease of use and fast warm-up via forced-air delivery. As a propane-fired forced-air appliance, it requires adequate ventilation and clearance. Its basic control layout makes it suitable for users who want a straightforward heater without advanced electronics.

Dura Heat LPC80 50–80,000 BTU Propane Convection Heater

Check Price on Amazon

The Dura Heat LPC80 is a high-capacity convection heater with a variable output of 50,000–80,000 BTU, effectively covering large garages (manufacturer lists up to ~1,900 sq ft). It offers 360° convection to distribute heat evenly and can operate up to 17 hours on a 40 lb cylinder.

This model requires no electricity for ignition (piezo igniter) and is meant for continuous warming rather than rapid spot heating. It suits larger spaces or users wanting longer runtime and broad coverage. Proper fuel hookup, venting, and clearance are essential for safe operation.

Mr. Heater F260560 Big Maxx MHU80NG Natural Gas Unit Heater

Check Price on Amazon

The Mr. Heater Big Maxx MHU80NG is an 80,000 BTU natural gas unit heater intended for permanent installation in garages, workshops, or commercial spaces. The package includes angle brackets and an LP conversion kit, making it adaptable to fuel source changes by qualified technicians.

This unit is built for hard-mounted use and covers large areas (manufacturer lists ~2,000 sq ft). It runs on natural gas, so it avoids cylinder refills but requires gas line connection and adherence to clearance and venting categories. Thermostat, hose, and regulator are not included in the base package.

Reznor UDXC-45 Natural Gas Ceiling/Wall Garage Heater

Check Price on Amazon

The Reznor UDXC-45 is a ceiling-mount natural gas heater for indoor use. While rated at 45,000 BTU with two selectable output levels, it functions as an efficient option for moderate-sized garages and shops and boasts an 83% thermal efficiency rating.

Its design includes suspension points for ceiling mounting and a low-static propeller fan for quieter operation. This heater is suitable where a hard-mounted natural gas solution is preferred over portable propane. Installation requires proper mounting hardware and professional gas hookups.

Buying Guide: Choosing The Right 60,000 BTU Garage Heater

Selecting a heater that delivers around 60,000 BTU involves assessing several factors. Below are key considerations and comparison perspectives to guide a practical decision.

Fuel Type: Propane, Natural Gas, Or Electric

• Propane: Portable, high output for short-term or intermittent use. Requires cylinder storage and ventilation. Good for rental properties or temporary work sites.
• Natural Gas: Best for permanent installations with existing gas lines. Provides continuous supply and lower operating disruptions; requires professional installation and clearance adherence.
• Electric: Cleaner indoor operation and simpler installation (often hardwired). Electric heaters that match 60,000 BTU equivalent are high-power (240V, hardwired) and can be costly to operate depending on electricity rates.

Heat Delivery: Forced-Air Vs. Convection Vs. Infrared

• Forced-Air: Rapid warm-up and circulation; ideal for spot heating and intermittent use. May be noisier and require ventilation for fuel-burning units.
• Convection: Gentle, even heating for whole spaces. Convection units (like 360° designs) maintain ambient temperature efficiently but may take longer to warm a cold space.
• Infrared: Heats objects and people directly rather than the air; effective for outdoor or semi-enclosed areas and for focused workstations.

Installation And Mounting

• Portable Units: Offer mobility and simple setup but need safe fuel placement and clearances. Good for temporary or multiple-location use.
• Ceiling/Wall-Mount Units: Save floor space and provide permanent, distributed heating. Require secure mounting, proper clearances, and professional gas/electrical work.
• Hardwired Electric: Must be installed by a qualified electrician; consider available circuit capacity and breaker sizing for high-power units.

Size, Coverage, And BTU Matching

• Estimate cubic feet: multiply garage square footage by ceiling height. A 60,000 BTU output is typically suited for medium-to-large garages, but insulation level dramatically affects performance.
• Well-insulated garages need less BTU; poorly insulated or frequently opened spaces will require more output and possibly supplemental heaters.

Runtime, Fuel Capacity, And Convenience

• For propane heaters, check estimated runtime on common cylinder sizes (20 lb or 40 lb). Longer runtime reduces refill frequency.
• Natural gas and electric eliminate cylinder management but require fixed utilities.

Safety Features And Compliance

• Look for overheat protection, tip-over switches, and thermal cut-outs on portable and electric units.
• Fuel-burning heaters need proper ventilation, combustion air clearance, and adherence to local codes. Confirm manufacturer clearances and certified listings (ETL, CSA, etc.).
• Hardwired or gas installations should be performed by licensed professionals to meet code and insure safe operation.

Noise, Air Movement And Comfort

• Forced-air units deliver quick heat but often generate more noise. Models with quieter burner technology reduce disruption in workshops.
• Convection units produce quieter, more uniform heat. Infrared units are silent and focused but may not heat large volumes of air effectively.

Efficiency And Operating Cost

• Evaluate fuel cost per BTU in your region (propane vs. natural gas vs. electricity). Higher initial cost for a permanent natural gas or electric unit can be offset by lower operating hassle and potentially better efficiency.
• Check manufacturer-stated efficiency where available; higher efficiency reduces wasted fuel and lowers long-term cost.

Maintenance And Longevity

• Routine maintenance includes cleaning air intakes, checking ignition components, and inspecting gas connections for fuel-burning models.
• Forced-air blowers and fans may need periodic lubrication and filter checks if applicable.

Comparison Perspectives

• Best For Portability: Propane forced-air models with handles and compact design.
• Best For Permanent Heating: Natural gas unit heaters or hardwired electric ceiling units.
• Best For Quiet Operation: Units marketed with quieter burner tech or low-static fans.
• Best For Long Runtime: Larger propane cylinder-compatible units or natural gas systems.

Use the above considerations to match heater features to your garage size, insulation, installation willingness, and preferred fuel type. Always prioritize code-compliant installation and follow manufacturer safety directions for fuel-burning appliances.
