Mr. Heater MH60QFAV 60,000 BTU Propane Heater
This model is a portable propane forced-air heater with a variable output from 30,000 to 60,000 BTU. It uses QBT (Quiet Burner Technology) for reduced noise versus standard models. The unit is compact and intended for garages, workshops, and jobsite tents where a reliable, mobile heat source is needed. Run-time is extended on larger tanks, and the heater is designed for quick warm-up and forced-air distribution.
Key features include variable heat output, quieter operation, and portability suited for temporary heating needs. Ideal for smaller to medium garage spaces where propane is preferred and noise reduction is desirable.
InoKraft MaXheat MH68 68,000 BTU Propane
The InoKraft MaXheat MH68 provides a variable output of 30,000–68,000 BTU and claims coverage up to 1,600 sq. ft. It emphasizes fast heating with a heavy-duty forced-air fan and adjustable heat angle to direct warm air where needed. Safety elements include overheat auto-shutoff and auto-cut-off protection, and the unit is CSA certified.

This unit suits medium-sized garages and shops requiring faster warm-up and directional control. The 10 ft hose and regulator and lower noise design make it a practical choice where frequent repositioning and focused heat are necessary.
Mr. Heater 125,000 BTU Forced Air Heater
This high-output forced-air propane heater is built for larger garage spaces and heavy-duty jobsite use. It utilizes Quiet Burner Technology to reduce sound and includes a 10 ft hose & regulator and a high-temperature limit switch for safety. The design focuses on delivering substantial airflow and high BTU output to heat more substantial volumes.
Best suited for large, open garages, shops, or combined garage/workspaces where a single, powerful heat source is needed and propane infrastructure is available.
Mr. Heater 80,000 BTU Multi-Fuel Kerosene Heater
Unlike propane-only torpedo heaters, this multi-fuel forced-air unit accepts kerosene, filtered diesel, fuel oil, and jet fuels, providing flexibility where propane is not preferred. At 80,000 BTU, it’s rated for up to approximately 2,000 sq. ft. and includes a built-in thermostat plus LED troubleshooting diagnostics for maintenance support.

This model is appropriate for garages where liquid fuels are more accessible, or where long-term onsite storage and different fuel options are required. Note that fuel handling and ventilation considerations differ from propane models.
Master MH-125V-GFA-A 125,000 BTU LP Heater
The Master MH-125V-GFA-A is a variable-output LP forced-air heater designed for very large garages, shops, or warehouse spaces. With capacity to warm up to roughly 3,100 sq. ft., it features adjustable heat settings for tailored performance and extended run times on larger propane supplies.
Choose this when consistent, high-output heating across a large enclosed garage or connected workshop is necessary. The variable settings help modulate fuel use and match output to changing conditions.
Buying Guide For Garage Torpedo Heaters
Selecting the right torpedo heater combines assessing space size, fuel logistics, safety features, and intended use. Below are core considerations and comparison perspectives to guide a purchase.
1. BTU Output And Coverage
BTU ratings indicate heating capacity. For single-car garages, 30,000–68,000 BTU units often suffice. For larger or multi-bay garages, 80,000–125,000 BTU and higher are better. Estimate square footage and ceilings: higher ceilings require more BTUs to maintain comfortable working temperatures.
2. Fuel Type And Availability
Common fuels: propane, kerosene, diesel, and LP. Propane units are portable and convenient with regulated tanks. Multi-fuel and kerosene units offer flexibility where liquid fuels are easier to store or source. Consider local fuel access and storage rules.
3. Ventilation And Indoor Use
Forced-air torpedo heaters produce combustion byproducts; many require well-ventilated spaces or outdoor use per manufacturer guidance. Check whether a model is approved for indoor garage use and follow ventilation recommendations to control fumes and carbon monoxide risks.
4. Safety Features
Look for overheat auto-shutoff, thermoelectric safety valves, high-temperature limit switches, and stable mounting or stands. Built-in thermostats and diagnostic LEDs help maintain safe operation and identify faults early.
5. Noise And Comfort
Quiet Burner or QBT technology reduces operational noise. If you use the heater in a workshop where communication or concentration matters, quieter models reduce distraction while still delivering heat.
6. Portability And Hose/Regulator Length
Portable torpedo heaters should have manageable weight, handles, and sufficient hose length (commonly 10 ft) to position the unit safely away from the work area while maintaining fuel connection convenience.
7. Run Time And Tank Compatibility
Run time varies by BTU setting and tank size. Variable-output heaters allow lower settings to extend run time. If continuous long sessions are needed, evaluate compatibility with larger tanks or refill frequency.
8. Maintenance And Spare Parts
Consider ease of filter access, burner maintenance, and availability of replacement parts. Units with simple diagnostics and common part compatibility reduce downtime and service costs.
9. Fuel Efficiency And Control
Variable heat output models provide better fuel economy for fluctuating conditions. Thermostatic control can prevent unnecessary fuel use by maintaining target temperatures instead of running at full output continuously.
10. Use Case Comparisons
- Small Personal Garage: Lower BTU propane models (30k–68k) offer portability and quick warm-up.
- Large Workshop/Warehouse: High-output units (125k+) or variable-output industrial heaters provide broader coverage and consistent temperatures.
- Remote Jobsite: Durable forced-air propane or diesel/kerosene units with long run times and robust construction are preferred.
- Intermittent Use: Quiet burner, variable-output options reduce noise and fuel consumption for occasional tasks.
When selecting, match the heater’s BTU capacity to your garage size, choose the fuel type you can safely store and access, prioritize units with approved indoor use when operating inside, and select safety features appropriate for occupied workspaces.
