Dyna-Glo 50K-200K Propane Heater
This model offers a wide BTU range (50,000–200,000), intended for large commercial or outdoor-covered spaces. Manufacturer notes the unit heats up to 4,700 sq. ft. when ventilation and clearances meet guidelines. It’s described for both outdoor and indoor construction/commercial use with proper ventilation, which emphasizes the importance of following local codes and ensuring airflow when used inside enclosed areas.
Key features include high output for large-volume spaces and a design aimed at construction or commercial settings. Users evaluating this heater should consider ventilation requirements, clearance distances, and fuel hookup capacity for continuous high-BTU operation.
Mr. Heater 30K–80K Convection Heater
Designed for mid-sized spaces, this unit delivers 30,000–80,000 BTU per hour and is rated to heat around 2,000 sq. ft. The product description specifies operation up to 14 hours on a 100 lb. propane tank, and it uses a standing pilot for continuous ignition and an added layer of safety. The standing pilot design can be preferable for workshop or shop use where intermittent power is a factor.
Consider this heater when looking for a balance of output and runtime. Its feature set highlights long runtime on large tanks and pilot-based ignition, which may reduce startup cycles compared with intermittent ignition systems.
ProTemp 80,000 BTU LP Heater
The ProTemp PT-80V-LPC is CSA certified for safety and specified to heat spaces up to 1,800 sq. ft. It uses a 20 lb propane tank and is targeted at garages, workshops, and construction environments. The certification indicates the unit meets certain safety standards which can be important for indoor-adjacent uses under proper ventilation.
Primary considerations with this model include CSA certification, tank size compatibility, and intended coverage area. Its certification can make permitting or code compliance easier in some contexts.
Dura Heat LPC80 50–80K Heater
The Dura Heat LPC80 is a 360-degree convection heater with variable output from 50,000–80,000 BTUs. It runs up to 17 hours on a 40 lb. cylinder and features a piezo igniter, supporting operation without external electricity. The manufacturer specifies a maximum room size near 1,900 sq. ft.
Its strengths are variable output, long runtime on larger cylinders, and no-electric ignition. Evaluate this unit for settings where electricity is limited and a full 360-degree heat dispersion is preferred for open-floor workshops or barns.
Mr. Heater MH200C 200K Propane Heater
This high-capacity unit features adjustable output and is CSA certified, with a 10-foot LP gas hose included. As a high-BTU solution, it’s intended for very large, well-ventilated spaces or commercial applications. The adjustable setting allows matching heat to specific space demands while the certification supports safety and compliance.
Consider this model when maximum output and flexible installation options (hose length and adjustment) are priorities. Installation planning should address fuel supply, ventilation, and clearances for large-output systems.
Buying Guide
This buying guide highlights the most important factors when choosing a propane convection heater for garages, workshops, and similar spaces. Compare models across performance, safety, fuel compatibility, and installation needs.
1. BTU Output And Coverage
Match BTU output to the cubic volume of the space. Higher BTUs heat larger volumes faster, but require more ventilation and fuel delivery capacity. Use manufacturer coverage estimates as a baseline and account for insulation, ceiling height, and door openings when sizing.
2. Ventilation And Intended Use
Convection heaters move warm air through a space, so ventilation is critical if used indoors. Many listed units are intended for outdoor or commercial indoor use with proper ventilation. Check local codes and ensure adequate fresh-air intake and exhaust where required.
3. Safety Features And Certifications
Look for CSA certification, Oxygen Depletion Sensors (ODS), tip-over protection, and reliable ignition systems. Certifications indicate third-party testing, which can affect compliance and insurance. ODS and pilot/tip-over features add layers of safety for indoor-adjacent use.
4. Fuel Source, Tank Size, And Runtime
Confirm compatibility with common propane cylinders: 20 lb, 40 lb, or 100 lb. Larger tanks extend runtime but require secure mounting or placement. Product specs often list expected hours of operation on specified tank sizes—use these to plan refueling logistics.
5. Ignition Type And Power Needs
Ignition options include piezo igniters, standing pilot, and electronic ignition. Piezo and standing pilot systems generally don’t require external power, while electronic ignition may need batteries or electricity. Choose based on availability of power and desired startup behavior.
6. Portability And Installation
Consider weight, mounting options, and included accessories such as gas hoses. Portable units simplify repositioning, while larger heaters may require permanent mounting and professional installation for gas supply and clearances.
7. Heat Distribution Style
Some heaters offer 360-degree convection; others focus on directional discharge. 360-degree units evenly warm open areas, while directional units may be better for targeted heating near workstations or doorways.
8. Maintenance And Durability
Review construction materials, ease of cleaning, and replaceable parts. Convection heaters in dusty or workshop environments will need periodic cleaning and inspection of gas fittings and ignition components.
9. Noise, Pilot Life, And Operating Considerations
Standing pilot systems can produce continuous low-level flame and minor noise; electronic ignition reduces continuous pilot fuel consumption. Consider whether continuous pilot aligns with your fuel-efficiency goals and site noise tolerance.
10. Comparison Perspectives
- High-Capacity/Commercial: Choose models with 150,000–200,000 BTU output and robust installation options for large enclosed or semi-enclosed sites.
- Mid-Sized Workshops: Models in the 30,000–80,000 BTU range often balance coverage and runtime for typical garages and workshops.
- Portability And Off-Grid Use: Units with piezo igniters and compatibility with common cylinder sizes offer flexibility where electricity is limited.
- Certified Indoor-Adjacent Use: Prioritize CSA or similar certification and ODS when using in partially-enclosed spaces.
When selecting a propane convection heater, weigh space size, ventilation capability, certification, fuel logistics, and ignition type to align with safety requirements and heating goals. Always follow manufacturer installation and clearance instructions and consult local codes for indoor use.
