Key Features: 50,000–80,000 BTU output, designed for commercial/industrial durability. The unit is intended for sites that can provide ventilation and space for safe operation of high-BTU propane equipment.

Use Cases & Considerations: Best suited for large, well-ventilated garages, shops, or temporary job-site enclosures. Verify local codes and manufacturer instructions for indoor operation and maintain clearance around the heater to avoid heat damage to nearby objects.

Dura Heat LPC80 50–80K Propane Convection

Check Price on Amazon

Output Range: 50,000–80,000 BTU. Coverage: Up to 1,900 sq. ft. The Dura Heat LPC80 offers 360-degree convection and variable output to match load requirements.

Key Features: 360-degree convection, variable output between 50K and 80K BTU, piezo igniter, runtime up to 17 hours on a 40 lb cylinder, no electricity required. The full rotation convection design distributes heat around the unit for more uniform warming in open spaces.

Use Cases & Considerations: Effective in barns, workshops, and larger garages where multi-directional heat distribution is desirable. The piezo igniter avoids dependency on mains power, but always observe ventilation and clearance specifications for safe operation.

ProTemp 80,000 BTU LP Convection Heater PT-80V-LPC

Check Price on Amazon

Output Range: 80,000 BTU (single high-output). Coverage: Up to 1,800 sq. ft. ProTemp emphasizes safety with CSA certification and is positioned for heating larger enclosed spaces.

Key Features: CSA certification for safety, designed to work with a 20 lb propane tank, intended for large garages, barns, and workshops. The unit aims to balance strong output with regulated construction and safety standards.

Use Cases & Considerations: Suited for homeowners and professionals who require a CSA-certified heater for larger enclosed spaces. Using a 20 lb tank improves convenience and portability; verify runtime expectations based on tank size and output setting.

Master MH-80V-LPC-A Variable Output Convection

Check Price on Amazon

Output Range: Variable 60,000 / 70,000 / 80,000 BTU. Coverage: Up to 2,000 sq. ft. The Master model provides selectable output levels, enabling closer matching of heat to room load and reducing wasted fuel.

Key Features: CSA certification, multiple BTU settings, designed to heat up to 2,000 square feet. Variable output can improve efficiency in changing conditions, and CSA certification supports safety compliance in many professional settings.

Use Cases & Considerations: Good choice where flexible heat levels are needed—for example, warming a shop during intermittent use. Confirm installation clearances and whether hard-mounted or portable placement best fits your workspace.

Buying Guide: How To Choose A Portable Propane Convection Heater

Choosing a propane convection heater requires balancing BTU output, coverage area, fuel compatibility, and safety certifications. Consider the following criteria to match a heater to your space and needs.

1. BTU Output And Room Size

BTU indicates heat output. For workshops and garages, models between 50,000–80,000 BTU commonly heat 1,000–2,000 sq. ft., depending on insulation and ceiling height. Estimate heat loss for uninsulated spaces and select higher BTU or multiple units accordingly.

2. Convection Versus Radiant Heat

Convection heaters warm air and circulate heat through the room for even temperature. They are preferable for whole-room warmth. Radiant heaters warm objects and people directly; they are better for spot heating or outdoor use. This guide focuses on convection models for area heating.

3. Fuel Tank Size And Runtime

Run time depends on BTU draw and tank capacity. Units designed for 20 lb tanks are convenient and portable. Models that specify run hours on 40 lb or 100 lb tanks indicate suitability for longer unattended operation. Match tank size to how long you need continuous operation.

4. Ignition Type And Power Requirements

Piezo or standing pilots are common. Piezo igniters spark without electrical power and are useful in off-grid locations. Standing pilots keep the pilot lit continuously, allowing instant heat but consuming small amounts of gas continually. Decide based on convenience and fuel economy.

5. Safety Features And Certifications

Look for safety elements like CSA certification, tip-over shutoff, pilot safety valves, and low-oxygen shutoff (ODS) for indoor use. CSA or equivalent certification demonstrates independent testing. Always follow manufacturer ventilation and clearance guidelines.

6. Portability And Installation

Consider weight, handles, wheel kits, and footprint. Portable convection heaters are beneficial when moved between job sites or different rooms. If the heater will be mounted, verify mounting options and professional installation requirements.

7. Ventilation And Indoor Use

Propane combustion produces combustion byproducts; ensure adequate ventilation for any indoor use. Some models are labeled for indoor use with required clearances, while others are intended primarily for well-ventilated or outdoor applications. Follow local codes and manufacturer instructions.

8. Variable Output And Fuel Efficiency

Variable-output models allow matching BTU to demand, improving fuel efficiency and comfort. If you need both heavy-duty heating and occasional low-level warmth, a heater with selectable BTU settings offers greater control.

9. Maintenance And Serviceability

Inspect pilot assemblies, regulators, hoses, and fittings periodically. Choose models with accessible parts and clear service documentation. Regular maintenance reduces risk and maintains performance.

10. Comparison Perspectives

• Performance: Compare maximum BTU and claimed coverage to your space’s volume rather than floor area alone.
• Safety: Give priority to CSA-certified heaters for indoor or professional settings.
• Operational Cost: Higher BTU gives faster heat but increases fuel consumption; match capacity to need.
• Portability: If moving between sites, prefer units sized for handling with a 20 lb tank compatibility.

Selecting the right portable propane convection heater depends on the size of the area to be heated, ventilation availability, desired runtime, and safety requirements. Use the BTU, certification, and portability criteria in this guide to narrow options and confirm the best fit for your workspace.
