ProTemp 80,000 BTU LP Propane Convection Heater

Check Price on Amazon

This propane convection heater is designed for large, open spaces. The unit is CSA certified, indicating compliance with recognized safety standards for propane appliances. It is rated to heat up to 1,800 square feet, making it suitable for many garage and workshop layouts.

Notable listed features include compatibility with a 20 lb propane tank for extended run times and fewer refills. Convection heating distributes warmed air throughout the space rather than focusing on direct radiant warmth, which helps maintain a more uniform ambient temperature in enclosed garages or larger work areas.

Use cases: This heater fits scenarios where ventilation is addressed and a portable propane source is preferred. Consideration should be given to indoor ventilation, carbon monoxide monitoring, and proper clearance recommendations per manufacturer guidance.

L.B. White CV250 Workman 225 Plus Portable Heater

Check Price on Amazon

The L.B. White CV250 Workman 225 Plus is a high-output portable propane convection heater with a one-piece barrel design. The product emphasizes easy maneuverability and no assembly required, beneficial for temporary or multi-location use in job sites and larger garages.

Features include a piezo pilot ignition for simple startup without external power and a design aimed at quick placement. The convection-style barrel moves warm air into a space rather than relying solely on radiant heat, which can help heat the overall room more evenly.

Use cases: Ideal where portability and quick deployment are priorities. As with other propane convection units, follow ventilation and clearance guidelines and use appropriate monitoring for indoor operation to ensure safe air quality.

Dyna-Glo Liquid Propane Convection Heater

Check Price on Amazon

The Dyna-Glo RMC-LPC200DG is a high-capacity liquid propane convection heater offering between 50,000 and 200,000 BTUs. The broad BTU range and high maximum output make it suitable for very large garages, workshops, or commercial spaces where substantial heat is required.

Manufacturer notes that the unit can heat up to 4,700 square feet under appropriate conditions. The product is intended for indoor or outdoor construction and commercial environments with proper ventilation and installation practices.

Use cases: Best for oversized spaces or commercial settings where high output is necessary. Evaluate ventilation, fuel hookup, and clearance before installation. This model suits scenarios where a single high-output convection source is needed rather than multiple smaller heaters.

TEMPWARE 7500-Watt Electric Fan-Forced Garage Heater

Check Price on Amazon

This electric fan-forced heater mounts to the ceiling and is hardwired at 240 volts. With a max output equivalent to roughly 25,590 BTU and adjustable power settings, the unit targets garages up to about 1,250 square feet depending on insulation and layout.

Key features listed include adjustable louvers to direct airflow, an ECO mode

Use cases: Electric fan-forced units are advantageous where propane use is restricted or where continuous indoor ventilation is limited. They require appropriate electrical capacity and professional hardwiring for safe installation.

Ballu Convection Panel Space Heater With Wi‑Fi

Check Price on Amazon

The Ballu panel is an electric convection-style space heater featuring a patented Hedgehog heating element for faster warm-up and improved heat transfer. It is marketed for whole room use up to 250 sq.ft. as primary heat and larger areas as supplemental heat.

Features include a program thermostat, Wi‑Fi app control, remote, and compatibility with voice assistants. The manufacturer highlights rapid heat-up and long-lived heating element design with a two-year warranty.

Use cases: Suited for smaller garages or specific zones within a larger space where electric convection panels can supplement central heating or provide localized warmth with smart controls and scheduling.

Buying Guide: Choosing The Right Convection Garage Heater

Selecting a convection heater for a garage requires balancing fuel source, output, safety, installation, and operational costs. Below are key considerations presented from multiple perspectives to help match a heater to your needs.

1. Fuel Type And Availability

• Propane / Liquid Propane: Offers high BTU output and portability. Good for large or remote workshops without robust electrical service. Requires storage for tanks and attention to ventilation and CO monitoring.
• Electric (Hardwired or Plug-In): Cleaner indoor air, no combustion byproducts. Requires adequate electrical capacity and may be limited in maximum output compared with LP for large spaces.

2. Heating Capacity And Space Size

• Estimate required BTUs by space volume, insulation, and ambient temperatures. Larger, poorly insulated garages need higher BTUs or multiple units.
• Manufacturers often list square-foot coverage; treat these as estimates and consider insulation, ceiling height, and doors opening frequently.

3. Type Of Heat Distribution

• Convection Heaters: Warm air circulates, producing more even ambient temperature—suitable for whole-room comfort.
• Fan-Forced / Panel: Faster warm-up and directed airflow. Ceiling-mounted fan-forced units move air quickly through the space.
• Radiant / Infrared: Heats objects and people directly; less effective at warming overall air in large volumes but efficient for task areas.

4. Safety Features And Certifications

• Look for certifications like CSA, ETL, or UL for equipment safety verification.
• Key safety features include overheat protection, tip-over switches (for portable electric units), and for combustion heaters, oxygen depletion sensors or CO monitoring and proper ventilation instructions.

5. Installation And Ventilation

• Hardwired Electric: Requires qualified electrician and adequate circuit capacity.
• Propane/LP: Consider tank size, hose routing, clearance, and local codes. Indoor combustion requires ventilation and monitoring.
• Clearance to combustibles and adherence to manufacturer installation diagrams are essential for safe operation.

6. Noise, Controls, And Usability

• Fan-forced units can be noisier than passive convection panels; evaluate noise tolerance when selecting a model.
• Thermostats, timers, remote control, and smart app/Wi‑Fi features affect convenience and energy management.

7. Portability Versus Fixed Installation

• Choose portable propane or wheeled electric units if you need to move heat between spaces.
• Ceiling or wall-mounted units provide permanent coverage and free floor space but reduce flexibility.

8. Running Costs And Efficiency

• Estimate operational costs based on local electricity and propane prices. Electric heaters often have predictable costs per kWh, while propane cost varies with tank sizing and usage.
• Features like ECO mode, thermostats, and timers reduce wasted runtime and improve efficiency.

9. Maintenance And Longevity

• Combustion units require inspection of burners, fuel lines, and ignition components. Electric units need periodic cleaning to keep vents and fans clear.
• Check warranties and element lifespans for panel-style heaters; some list long-life elements as a benefit.

10. Regulatory And Local Code Considerations

• Review local building codes for indoor combustion heaters and required clearances or venting.
• Some rental properties or municipalities restrict indoor propane use—verify before purchase and installation.

Comparing across these perspectives—fuel, output, installation complexity, safety, and running costs—will help narrow options. For large, intermittently used garages, high-BTU propane convection units offer portability and raw power. For continuous indoor use with minimal ventilation concerns, electric fan-forced or convection panels provide cleaner operation and simpler installation when electrical capacity permits.
