Mr. Heater Convection Heater 30–80K BTU
This Mr. Heater model is a variable-output convection heater designed for propane use with a 30,000–80,000 BTU range. The manufacturer states it can heat up to 2,000 sq. ft. and operates up to 14 hours on a 100 lb. propane tank. The unit uses a standing pilot system for continuous ignition and includes features typical of shop heaters: durable housing and controls for output adjustment.
As a convection device, heat distribution relies on natural and induced air movement rather than infrared radiation. That makes this unit suitable for warming larger volumes of air in garages and workshops. The standing pilot simplifies relighting but requires consideration for installation and ventilation guidelines provided by the manufacturer.
Dyna-Glo RMC-LPC80 Convection Heater
The Dyna-Glo RMC-LPC80 offers 50,000–80,000 BTU output and is rated to heat areas up to 2,000 sq. ft. Manufacturer guidance notes the unit is suitable for both outdoor and indoor use in commercial settings when proper ventilation is provided.
This heater’s construction supports robust, continuous operation in large spaces. As a convection unit, it distributes warm air rather than delivering radiant heat to specific objects. Users should follow ventilation and clearance requirements for indoor use and consider a propane supply compatible with the listed BTU consumption for longer run times.
Dura Heat LPC80 50–80K Propane Heater
The Dura Heat LPC80 is a 360-degree convection heater with variable output between 50,000 and 80,000 BTUs. The manufacturer specifies operation up to 17 hours on a 40 lb. cylinder and a maximum room size near 1,900 sq. ft.
This model emphasizes simple piezo ignition and no-electric operation. The 360-degree convection design can help promote more uniform air mixing in open spaces. Considerations for indoor use include meeting ventilation and clearances per the product manual, and planning propane supply capacity based on runtime and BTU setting.
ProTemp 80,000 BTU LP Convection Heater
The ProTemp PT-80V-LPC is rated at 80,000 BTU and is CSA certified for safety. The manufacturer lists effective heating up to 1,800 sq. ft. and notes use with a 20 lb propane tank for extended operation without frequent refueling.
As a convection heater, the ProTemp model focuses on heating air for large enclosed areas like workshops and garages. CSA certification indicates adherence to specific safety standards, which can be important for workplace or commercial installations. Users should verify local codes and ventilation requirements when using propane-fired devices indoors.
Master MH-80V-LPC-A Convection Propane Heater
The Master MH-80V-LPC-A offers variable output options (60,000 / 70,000 / 80,000 BTU) and is CSA certified. The manufacturer indicates coverage up to 2,000 sq. ft., making it suitable for larger workshops and construction zones requiring adjustable heat delivery.
Variable output allows matching heat production to space size and insulation conditions, which can improve fuel efficiency. The Master unit’s certification and adjustable settings make it a versatile choice for environments where different operating scenarios arise. Adequate ventilation and clearance remain essential for safe indoor use.
Buying Guide: Choosing A Portable Propane Convection Heater
When selecting a portable propane convection heater, evaluate these key factors to match the appliance to your space and use case.
1. BTU Output And Coverage
- Match BTU to Space: Use manufacturer BTU and coverage guidance; larger, poorly insulated areas require higher BTUs.
- Variable Output: Units with adjustable BTU settings provide flexibility and can improve fuel economy.
2. Convection Versus Radiant Heat
- Convection Heaters warm the air, suitable for overall room heating and high ceilings.
- Radiant Heaters warm objects and people directly, better for spot heating or open outdoor areas.
- Choose convection models for garages, workshops, and barns where ambient temperature needs raising.
3. Fuel Supply And Runtime
- Tank Size Compatibility: Confirm which propane cylinder size the unit is designed to use (20 lb, 40 lb, 100 lb).
- Runtime Estimates: Compare manufacturer runtime listings at typical BTU settings to plan refueling intervals.
4. Safety Features And Certifications
- Certifications: CSA or other certifications indicate compliance with safety standards.
- Automatic Shutoffs: Look for low-oxygen cutoffs, tip-over shut-offs, and flame failure protection.
- Pilot Or Piezo Ignition: Standing pilot provides continuous ignition; piezo igniters avoid external power sources.
5. Ventilation And Indoor Use
- Follow Manufacturer Guidance: Some models list indoor use with proper ventilation; always follow clearances and airflow recommendations.
- CO Risks: Propane combustion produces carbon monoxide; ensure adequate ventilation and consider CO detectors in enclosed spaces.
6. Portability And Installation
- Weight And Handles: Portable heaters should be manageable to move and place where needed.
- Mounting Options: Some shop heaters are floor-standing while others offer mounting kits; select based on workspace layout.
7. Durability And Intended Environment
- Construction: Look for rugged housings if unit will be used on job sites or in industrial settings.
- Weather Exposure: For outdoor or semi-exposed use, confirm the heater’s suitability for moist or dusty conditions.
8. Efficiency And Operating Costs
- BTU Per Hour Efficiency: Higher BTUs mean more heat but also faster fuel consumption; balance heat needs with runtime goals.
- Insulation And Drafts: Improving the space’s insulation can reduce necessary BTU capacity and operating costs.
9. Maintenance And Parts
- Serviceability: Check availability of replacement parts (orifices, regulators, ignition components) for long-term maintenance.
- Cleaning: Periodic inspection of burners and vents helps maintain safe, efficient operation.
10. Comparison Perspectives
- Performance Comparison: Compare BTU range and stated coverage for like-for-like performance in similar sized spaces.
- Safety Comparison: Prefer models with CSA certification and built-in safety cutoffs for indoor applications.
- Operational Comparison: Consider runtime claims relative to tank size; longer runtime reduces frequency of refueling during extended use.
