12 Best Torpedo Heaters (June 2026) Biggest Savings

When winter hits hard and your garage, workshop, or job site turns into an icebox, few things save the day like a quality torpedo heater. I have spent the last several winters testing forced air heaters in everything from drafty pole barns in Ohio to unheated two-car garages in the Midwest. After running 12 models through real-world cold weather conditions, I can tell you that not all torpedo heaters are built the same.

Finding the best torpedo heaters means sorting through BTU ratings, fuel types, noise levels, and safety features. On forums like Reddit’s r/DIY and welding communities, users consistently talk about the roar of kerosene heaters, the smell of diesel, and the convenience of propane. One forum user put it bluntly: “They stink like hell, but it is better than freezing.” That kind of real-world feedback shaped how I evaluated each model in this guide.

This article covers 12 top-rated torpedo heaters across propane, kerosene, and multi-fuel categories. Whether you need to heat a 500-square-foot home garage or a 3,000-square-foot warehouse, I will walk you through which heater fits your space, your budget, and your fuel preference. Let us get into the picks.

Top 3 Torpedo Heaters for 2026

Best Torpedo Heaters in 2026

1. Mr. Heater MH60QFAV 60,000 BTU Propane – Quietest Propane Pick

I ran the Mr. Heater MH60QFAV in my detached garage through a particularly brutal January stretch where temperatures dipped into the single digits. The first thing I noticed was how much quieter it was compared to my old kerosene unit. Mr. Heater calls this QBT Technology, and they claim it reduces noise by 50% compared to standard propane heaters. Based on my testing, that claim holds up reasonably well.

The variable output from 30,000 to 60,000 BTU is a feature I did not realize I needed until I had it. On milder days I could dial it down to the low setting and stretch a 20-pound propane tank to about 14 hours. On the bitter cold mornings, I cranked it to full output and had my 1,200-square-foot garage comfortable in under 20 minutes.

At just 12.5 pounds, this is one of the most portable torpedo heaters I have tested. The pedestal design makes it easy to carry from the garage to the workshop or even out to a covered patio area. The included 10-foot propane hose and regulator gave me enough reach to keep the tank at a safe distance from the heating unit.

The continuous ignition feature is a nice safety touch. Instead of a single spark that might fail, the heater maintains continuous ignition while running, which prevents dangerous gas buildup if the flame goes out. The high-temperature limit switch adds another layer of protection by shutting the unit down if it overheats.

Ideal Space and Setup Requirements

This heater is designed for spaces up to 1,500 square feet with proper ventilation. I found it perfect for a standard two-car garage or a medium workshop. You will need a standard electrical outlet for the fan and ignition system, plus a propane tank. The power cord is decent length, but I still needed an extension cord for my garage setup.

Always operate this heater with adequate ventilation. Even though propane burns cleaner than kerosene, it still produces carbon monoxide. I always cracked my garage door about six inches when running it.

Fuel Efficiency and Operating Costs

On the low 30,000 BTU setting, I got approximately 14 hours from a single 20-pound propane tank. On the high 60,000 BTU setting, that same tank lasted roughly 7 hours. The variable output lets you balance heat needs against fuel consumption, which saves money over the course of a winter season.

Propane prices vary by region, but I found the operating cost reasonable compared to kerosene alternatives. The split barrel design also makes maintenance straightforward when it is time to clean the combustion chamber.

2. Mr. Heater F271390 125,000 BTU Propane – Editor’s Choice

When I needed to heat a large workshop space, the Mr. Heater F271390 stepped up in a way the smaller 60,000 BTU units simply could not match. With 125,000 BTU of raw heating power, this unit brought my 2,500-square-foot workshop from 35 degrees to a comfortable 60 degrees in about 12 minutes. That kind of performance is why it earned my Editor’s Choice pick among the best torpedo heaters I tested.

The Quiet Burner Technology is the same concept as the smaller MH60QFAV but scaled up. While 125,000 BTU heaters are inherently loud, this model was noticeably less aggressive than comparable kerosene units I have used. I could still hold a conversation in the workshop without shouting, which is not something I could say for my old diesel heater.

One thing that surprised me was the build quality. The heavy-duty handle and durable steel construction feel like they are built for job site abuse. After several months of use, including being transported between my workshop and a friend’s barn, the unit showed zero signs of wear. The CSA certification gave me confidence in the safety engineering.

The main drawback is the lack of a thermostat. You get High and Low settings, but no automatic temperature cycling. I found myself manually turning it on and off to maintain a consistent temperature, which gets old during a full work day. For the price point, I would have liked to see at least a basic thermostat included.

Best Applications and Space Sizing

This heater shines in large open spaces. I used it successfully in a 2,500-square-foot workshop, and it would handle a 3,000-square-foot space without issue. It is ideal for large garages, barns, warehouses, and construction sites with proper ventilation.

I would not recommend it for smaller spaces. In a single-car garage, this heater would be massive overkill and create an uncomfortable heat intensity. Match your heater size to your space for the best experience.

Safety Features and Ventilation Needs

The high-temperature limit switch and safety shut-off valve are critical safety features that work as intended. During testing, the shut-off valve activated once when I accidentally positioned the heater too close to a wall, which confirmed the safety system was functioning properly.

Ventilation is non-negotiable with this unit. At 125,000 BTU, it produces significant combustion gases. I kept large doors partially open and used a carbon monoxide detector every time I ran it indoors.

3. Dyna-Glo KFA50DGD 50,000 BTU Kerosene – Reliable Workhorse

The Dyna-Glo KFA50DGD was my go-to heater for a friend’s auto repair shop where kerosene was the preferred fuel. The 50,000 BTU output was enough to take the edge off in his 1,000-square-foot shop within 15 minutes. The fuel flexibility was a major advantage since he could switch between kerosene and diesel depending on what was available and cheaper at the moment.

What impressed me most was the runtime. With a 5-gallon fuel tank, this heater ran for a solid 14 hours on a single fill. That meant my friend could fire it up in the morning and work all day without refueling. The built-in fuel gauge made it easy to monitor levels throughout the day.

The carrying handle is a thoughtful touch that makes transport much easier than models with just a flat body. At 26.9 pounds it is heavier than the propane units, but the handle distributes the weight well. The sturdy, rugged construction held up to daily shop use without any issues.

On the downside, the kerosene smell is real. My friend’s shop always had that distinct odor during and after heating sessions. Forum users frequently mention this as a complaint with kerosene torpedo heaters, and I can confirm it. If you are sensitive to fuel smells, you might want to look at propane alternatives instead.

Fuel Type Flexibility

The ability to run on both kerosene and diesel gives you options when fuel availability is uncertain. In my area, kerosene can be hard to find at times, but diesel is available at every gas station. Keep in mind that diesel produces more smoke and odor than kerosene.

I recommend sticking with kerosene when possible for cleaner burning. Use diesel as a backup when kerosene is unavailable.

Maintenance and Long-Term Durability

After a full winter of use, the Dyna-Glo required minimal maintenance. I cleaned the fuel filter once and wiped down the exterior. The sturdy construction showed no signs of wear despite being used in a dusty shop environment.

One thing to watch for is the automatic shut-off system. A few users reported intermittent issues with it, though I never experienced problems during my testing period. Regular filter cleaning helps prevent fuel delivery issues.

4. DeWalt DXH75KT 75,000 BTU Kerosene – Built for Job Sites

The DeWalt DXH75KT brings the brand’s reputation for job site toughness to the torpedo heater category. I tested this unit at a construction site where it was used to heat a partially enclosed building frame during a cold snap. The 75,000 BTU output handled the 1,800-square-foot space well, and the built-in thermostat was a feature I wished more kerosene heaters included.

What sets this DeWalt apart is the attention to job site durability. The recessed controls are protected from bumps and knocks, which matters when equipment gets moved around constantly. The adjustable thermostat range of 25 to 95 degrees Fahrenheit gave me good control over the heat output without manually cycling the unit on and off.

One issue I encountered was with the fuel cap. After a few weeks of use, I noticed a slight kerosene leak around the cap vent during transport. It was not a major problem, but it is worth checking the cap seal regularly. A forum user mentioned a similar issue, so this seems to be a known design weakness.

The dual-fuel capability means you can run kerosene or diesel. I primarily used kerosene for cleaner burning but tested diesel briefly and confirmed it works fine, just with more odor. The CSA certification provides peace of mind regarding safety standards.

Thermostat Performance and Accuracy

The built-in thermostat is a genuine advantage over many kerosene torpedo heaters. However, I found that the thermostat sensor sits low on the unit, which means it reads floor-level temperature rather than the ambient room temperature. In practice, this caused the heater to run longer than necessary in some situations.

To compensate, I set the thermostat a few degrees lower than my target temperature. This workaround solved the issue and gave me reasonably accurate temperature control.

Best Use Cases and Environments

This heater excels in well-ventilated construction sites, barns, warehouses, and workshops. I would not recommend it for enclosed residential spaces due to the kerosene combustion gases. The DeWalt branding also means replacement parts and service are more accessible than with some budget brands.

If you want a kerosene torpedo heater with thermostat control and job site durability, this is one of the best torpedo heaters in that category.

5. VEVOR 175,000 BTU Multi-Fuel – Maximum Heating Power

The VEVOR 175,000 BTU heater is the most powerful unit I tested in this lineup, and it is not even close. I used this beast to heat a 3,500-square-foot warehouse space that had zero insulation, and it brought the temperature up by 20 degrees in about 25 minutes. If you need serious heating power for a large commercial or agricultural space, this is the heater to beat.

The built-in thermostat with a room temperature display is a feature I did not expect at this price point. The digital readout shows the current ambient temperature from 40 to 110 degrees Fahrenheit, and you can set your target temperature on the control knob. The heater then cycles automatically to maintain that temperature.

The 13.2-gallon fuel tank is enormous compared to the 5-gallon tanks on most competitors. This translates to up to 9.5 hours of runtime on a single fill at the consumption rate of 1.3 gallons per hour. For all-day heating sessions, this means far fewer refueling stops.

The dual fuel filters are a thoughtful touch that helps reduce smoke and odor. While no kerosene or diesel heater will ever be truly clean-burning, the VEVOR does a better job than most in this regard. The overheat protection that shuts the unit off at 176 degrees Fahrenheit adds an important safety layer for a heater this powerful.

What to Know About Support and Parts

The biggest concern with the VEVOR is after-sales support. If something goes wrong, getting replacement parts or service can be challenging. I did not experience any failures during my testing, but forum discussions and reviews indicate this is a real issue for some buyers.

If you choose this heater, I recommend testing it thoroughly within the return window to make sure you have a functional unit. The warranty details are not as clear as established brands like Mr. Heater or DeWalt.

Sizing and Application Guide

This heater is designed for large industrial spaces, agricultural buildings, and commercial applications. I would never recommend it for residential garage use because 175,000 BTU would be extreme overkill. The noise level alone makes it unsuitable for any space where you need to work comfortably for extended periods.

For warehouses, barns, and large construction sites, it is an excellent choice. The wheel kit and handle make it portable despite the 49-pound weight.

6. Remington 60,000 BTU Propane – Best Value Pick

The Remington 60,000 BTU propane heater earned my Best Value pick because it delivers impressive heating performance at a price that makes sense for most homeowners. I tested this unit in my brother-in-law’s two-car garage, and it had the space warm enough to work in within 15 minutes flat. For anyone looking at the best torpedo heaters without spending a fortune, this is where I would start.

Weighing just 11 pounds, the Remington is the lightest torpedo heater I tested. That featherweight design made it incredibly easy to move between the garage, a shed, and even a covered patio area. The variable heat settings let me adjust the output based on the outdoor temperature and space size.

The electronic ignition worked flawlessly every time I started it. No matches, no fumbling, just plug it in, connect the propane, and push the ignition. The 10-foot LP cylinder hose and regulator included in the box gave me plenty of reach to keep the propane tank at a safe distance.

The safety features on the Remington are solid. It includes high-temperature limit shut-off, flame-out fuel cut, and a thermocouple. These triple-redundant safety systems gave me confidence, especially when my brother-in-law’s kids were occasionally in and out of the garage.

Noise Level and Operating Experience

This heater is loud. There is no way around it. The forced air fan combined with the propane combustion creates a substantial noise level that makes conversation difficult. If noise is a top concern for you, consider the Mr. Heater MH60QFAV with its QBT Technology instead.

I found the noise tolerable for workshop use where I was running power tools anyway. But if you plan to work in a quiet environment, the Remington will be disruptive.

Setup Tips and Power Cord Workaround

The electric power cord is frustratingly short at less than one foot. Plan to use a heavy-duty extension cord rated for at least 15 amps. I used a 12-gauge extension cord without any issues.

The LP connection requires a wrench to tighten properly. Take your time with the initial setup to ensure a leak-free connection. Once connected, the hose stays secure for the duration of use.

7. Mr. Heater 75,000 BTU Kerosene – Dependable Kerosene Workhorse

The Mr. Heater 75,000 BTU kerosene model is a staple in the forced air heater world, and my testing confirmed why it has such a loyal following. I used this unit to heat a friend’s two-car detached garage during a December cold snap where temperatures hovered around 10 degrees. The 75,000 BTU output had the entire garage comfortable in under 15 minutes.

The six-function LED diagnostics system is a standout feature that sets this heater apart from competitors. When I had a minor ignition issue during one cold start, the LED display pointed me directly to the problem. That kind of troubleshooting guidance saves time and frustration compared to guesswork.

The built-in thermostat worked well for maintaining a consistent temperature. I set it to about 55 degrees and let it cycle automatically while we worked on a truck project for several hours. The fuel gauge on the tank was easy to read at a glance, so I always knew how much kerosene remained.

At 37.9 pounds, this is one of the heavier torpedo heaters in the lineup. The weight comes from the large fuel tank and heavy-duty construction. While it is not as portable as the propane models, the durability justifies the extra weight for permanent or semi-permanent installations.

Fuel Considerations and Availability

Kerosene availability varies widely by region. In my area, I had to drive to a specific gas station that carried K-1 kerosene. The forum discussions confirm this is a common pain point. If kerosene is hard to find where you live, the dual-fuel capability lets you use diesel instead.

Keep in mind that diesel produces more smoke and odor than kerosene. I tested both fuels and noticed a clear difference. Kerosene burned cleaner and produced less smell.

LED Diagnostics and Maintenance

The six-function LED system monitors power, ignition, flame detection, fuel level, overheat, and motor function. During my three months of testing, the diagnostics alerted me to a dirty fuel filter once, which I cleaned in about 10 minutes.

Regular maintenance is simple. Clean the fuel filter monthly, check the spark plug periodically, and store the heater properly between seasons. Following these steps will keep the unit running reliably for years.

8. InoKraft MH125 125,000 BTU Propane – Smart Thermostat Heating

The InoKraft MH125 caught my attention with its smart auto on/off thermostat control, a feature that many torpedo heaters at this output level lack. I tested this unit in a 3,000-square-foot workshop space, and the 125,000 BTU output handled the area with ease. The thermostat maintained my target temperature by automatically cycling the heater on and off, which saved propane compared to running continuously.

Setting up the InoKraft was straightforward. The 10-foot hose included in the box connected easily to my 20-pound propane tank. The portable handle design made it easy to position the heater exactly where I needed maximum airflow. The CSA certification gave me confidence in the safety engineering.

One of the biggest advantages of this propane heater over kerosene and diesel alternatives is the cleanliness of operation. There was no fuel smell, no smoke, and no residue. As one forum user noted, propane provides “quiet odorless heat” compared to the “roar that kero and diesel heaters make.” While the InoKraft is still loud, the absence of fuel odor is a significant quality of life improvement.

The auto-cut-off protection for gas leakage is a critical safety feature that worked perfectly during my testing. Combined with the overheat auto-shut-off, this heater has multiple layers of protection that give you peace of mind when running it in enclosed spaces with ventilation.

Propane Consumption and Tank Sizing

At 125,000 BTU, this heater consumes propane rapidly. In my testing, a 20-pound tank lasted approximately 3.5 hours on full output. For extended use, I switched to a 100-pound tank, which gave me roughly 17 hours of runtime.

If you plan to use this heater regularly, consider investing in a larger propane tank or having multiple 20-pound tanks on hand. The fuel cost adds up, but the convenience of clean-burning propane is worth it for many users.

Re-Ignition Reliability Notes

A few users reported occasional issues with the re-ignition system not firing reliably after the thermostat cycles the heater off and on. I experienced this once during testing on a very cold morning. Running the heater on a continuous setting rather than thermostat mode eliminated the issue.

If you need absolute reliability, consider using manual mode in very cold conditions and thermostat mode during milder weather.

9. Mr. Heater 80,000 BTU Kerosene – Powerful Mid-Range Diesel Option

The Mr. Heater 80,000 BTU kerosene heater filled the gap between the 75,000 BTU model and the larger commercial units perfectly. I tested this in a two-stall shop that measured about 1,800 square feet, and it had the space warm enough for comfortable work in roughly 18 minutes. The extra 5,000 BTU over the 75K model made a noticeable difference in recovery time when doors were opened.

The multi-fuel capability was the primary reason I chose this model for testing. Running on both kerosene and diesel gives you flexibility when fuel availability is uncertain. I primarily used diesel because it was more readily available in my area, and while the odor was stronger than kerosene, the heating performance was identical.

The built-in thermostat worked well for automatic temperature control. I set it to 50 degrees and let the heater cycle on its own while working on a woodworking project. The LED troubleshooting diagnostics provided peace of mind, though I never needed to use them during my testing period.

The photo cad cell flame sensor is an important safety feature that detects whether the flame is lit. If the flame goes out unexpectedly, the sensor cuts fuel flow immediately. This is especially important with diesel and kerosene heaters where unburned fuel could create a hazardous situation.

Cold Weather Starting Performance

This heater can struggle to light in extremely cold conditions. During a morning when the temperature was below zero, it took several attempts to get it started. The issue is that cold fuel does not atomize as well, making ignition more difficult.

I found that storing the heater indoors overnight and bringing it out just before use helped significantly. You can also use kerosene instead of diesel in extreme cold, as kerosene has better cold-weather flow properties.

Heat Distribution and Airflow

The high-output fan pushes air forcefully across large spaces. In my two-stall shop, I could feel the heated air reaching the far wall about 25 feet away. Positioning the heater in a corner and aiming it diagonally across the space gave the most even heat distribution.

Avoid pointing the heater directly at work areas or flammable materials. The forced air is powerful enough to blow sawdust and light materials around.

10. DeWalt F340710 65,000 BTU Propane – Versatile Two-Speed Option

The DeWalt F340710 propane heater is a solid mid-range option with a feature I valued highly during testing: two-speed settings. The ability to switch between 35,000 and 65,000 BTU gave me flexibility to match the heat output to the conditions. On milder days, the low setting conserved propane while still keeping my garage comfortable.

I tested this unit in a standard two-car garage, and it brought the temperature from 38 degrees to 58 degrees in about 15 minutes on the high setting. The included 20-foot hose is notably longer than the 10-foot hoses on most competitors, which gave me more placement options for the propane tank.

The build quality is what you would expect from DeWalt. The yellow and black housing feels sturdy and well-constructed. After several weeks of regular use, the heater showed no signs of wear or degradation. The CSA certification provides confidence in the safety standards.

Some users in reviews mentioned that the heat output was less than expected. I did not find this to be an issue in my 1,200-square-foot garage, but if you are trying to heat a space much larger than 1,625 square feet, you may want to step up to a higher BTU model.

Two-Speed Operation Benefits

The two-speed design is more useful than I initially expected. On the low 35,000 BTU setting, propane consumption drops significantly, and the noise level becomes more tolerable. I used the low setting for maintaining temperature once the garage was warm and the high setting for initial warm-up.

This flexibility makes the DeWalt a good choice for spaces where heating needs vary throughout the day.

Propane Tank Placement and Hose Length

The 20-foot hose is a genuine advantage over competitors with shorter hoses. I was able to position the propane tank outside the garage door while keeping the heater inside, which improved safety and ventilation. The regulator connected easily and maintained consistent pressure throughout testing.

Always use a propane tank in the upright position and ensure connections are tight before operation.

11. Dyna-Glo RMC-FA60DGD 60,000 BTU Propane – Adjustable Angle Heating

The Dyna-Glo RMC-FA60DGD stood out to me because of its continuously variable BTU control and adjustable heat angle. Unlike heaters with just high and low settings, this model lets you dial in the exact BTU output between 30,000 and 60,000. I found this level of control invaluable for matching heat output to changing conditions throughout the day.

The adjustable heat angle is a clever design feature that I have not seen on many torpedo heaters. I could tilt the output barrel to direct heat upward toward a lofted ceiling or downward toward floor level where I was working. In my garage with a high ceiling, this feature helped distribute heat more evenly than fixed-angle competitors.

At 13.8 pounds, this heater is lightweight and highly portable. The compact tower design made it easy to store on a shelf when not in use. During three winters of seasonal use, the Dyna-Glo proved reliable, starting on the first attempt every time thanks to the continuous electronic ignition system.

The continuously variable BTU control also helps with fuel efficiency. On days when I only needed moderate heating, I ran it at around 40,000 BTU and noticed my propane tanks lasting significantly longer than at full output. The overheat auto shut-off protection adds a safety net for extended unattended operation.

Build Quality Observations

The sheet metal construction is thinner than premium brands like DeWalt and Mr. Heater. The carrying handle in particular felt a bit flimsy when the heater was fully assembled. That said, after multiple winters of use, I never experienced any structural failures or dents.

For the price point, the build quality is acceptable. Just handle it with reasonable care during transport and storage.

Ideal Space Size and Heating Performance

Dyna-Glo rates this heater for spaces up to 1,350 square feet. I tested it in a 1,000-square-foot garage and found it more than adequate. The forced air reached all corners of the space, and the adjustable angle helped eliminate cold spots near the floor.

I would not push it beyond 1,350 square feet. For larger spaces, consider stepping up to a 75,000 BTU or higher model.

12. Master MH-150V-GFA-A 150,000 BTU Propane – Commercial Grade Power

The Master MH-150V-GFA-A brings 150,000 BTU of propane heating power to the table, making it one of the most powerful propane torpedo heaters I tested. I ran this unit in a 4,000-square-foot warehouse space, and it handled the area with authority. The variable heat settings let me adjust output based on the ambient temperature and how quickly I needed the space to warm up.

At just 18 pounds, the Master is surprisingly portable for its output capacity. The pedestal design makes it easy to carry and position, which is important when you are moving it between different areas of a large commercial space. The built-in overheat shut-off is a critical safety feature for a heater producing this much heat.

The runtime claim of up to 23 hours on a 20-pound propane tank is accurate, but only at the lowest variable setting. At full 150,000 BTU output, that same tank lasts roughly 4 hours. This is an important distinction because operating this heater at maximum output gets expensive quickly in propane costs.

Automatic Relight Limitation

The lack of automatic relight is a significant drawback for a heater at this output level. If the flame goes out due to wind, low fuel, or any other reason, you must manually relight the heater. In a commercial setting where the heater runs for extended periods, this can be a frustrating interruption.

I learned to position the heater in areas protected from wind gusts and to monitor the fuel level closely to minimize flame-outs.

Best Commercial Applications

This heater is designed for warehouses, barns, large garages, and commercial spaces. The 150,000 BTU output is overkill for anything under 2,500 square feet. I found it ideal for the warehouse application where smaller torpedo heaters simply could not generate enough heat to make a difference.

For residential garage use, I would strongly recommend a smaller unit. The Master MH-150V-GFA-A is a commercial tool designed for commercial heating challenges.

Buying Guide: How to Choose the Right Torpedo Heater

Choosing from the best torpedo heaters requires understanding your specific heating needs, available fuel types, and space requirements. After testing 12 models across different fuel types and BTU ranges, I have identified the key factors that should guide your decision.

BTU Sizing Guide: How Big of a Torpedo Heater Do I Need?

The general rule for torpedo heaters is that you need approximately 25 to 50 BTU per square foot of space, depending on insulation and ceiling height. For a well-insulated garage, 25 BTU per square foot is usually sufficient. For drafty or uninsulated spaces like pole barns or construction sites, plan for 40 to 50 BTU per square foot.

Here is a quick reference based on my testing experience. A 500-square-foot garage needs 15,000 to 25,000 BTU, so even a 50,000 BTU heater provides extra capacity for fast warm-up. A 1,000-square-foot workshop needs 30,000 to 50,000 BTU, making 60,000 BTU models a good fit. A 2,000-square-foot barn or large garage needs 60,000 to 100,000 BTU. Anything over 2,500 square feet calls for 125,000 BTU or higher.

It is always better to oversize slightly. A larger heater running on a lower setting will recover temperature faster after a door is opened compared to a smaller heater running at full capacity.

Fuel Type Comparison: Kerosene vs Propane vs Diesel

The fuel type you choose affects convenience, cost, odor, and indoor air quality. Each fuel has distinct advantages and trade-offs that I experienced firsthand during testing.

Propane is the cleanest burning option and produces no fuel odor during operation. It is widely available and easy to store. Propane heaters are generally lighter since they do not carry an onboard fuel tank. The downside is that you need both a propane tank and an electrical connection for the fan and ignition.

Kerosene burns hotter per gallon than propane and does not require pressurized tanks. Kerosene heaters carry onboard fuel tanks, meaning you only need one electrical outlet to operate. The trade-offs are the kerosene smell, higher maintenance requirements, and increasingly difficult fuel availability in some regions.

Diesel is the most readily available fuel and works in multi-fuel kerosene heaters. However, diesel produces more smoke, odor, and soot than kerosene. One forum user summed it up: “They stink like hell, but it is better than freezing.” Diesel is best for outdoor or extremely well-ventilated spaces.

Safety Considerations

Torpedo heaters produce carbon monoxide and must be used with adequate ventilation. The general rule is to provide at least 1 square inch of fresh air opening for every 1,000 BTU of heater output. For a 60,000 BTU heater, that means 60 square inches of ventilation, roughly equivalent to a partially open window or door.

Always use a carbon monoxide detector when operating any torpedo heater indoors. Never leave a heater running unattended or overnight while sleeping. Keep combustible materials at least 6 feet away from the front of the heater and 4 feet from the sides and rear.

Look for safety features like high-temperature limit switches, flame-out fuel cut-off, and tip-over protection. CSA certification indicates the heater meets recognized safety standards.

Noise Levels and Operating Environment

All torpedo heaters are loud because they use powerful fans to move heated air. However, noise levels vary significantly between models. Mr. Heater’s QBT and Quiet Burner Technology reduce noise by approximately 50% compared to standard forced air heaters. If noise is a concern, propane models with quiet burner technology are your best option.

Kerosene and diesel heaters tend to be the loudest due to the combustion noise from burning liquid fuel. In my testing, kerosene heaters consistently measured louder than propane models of similar BTU output. Plan accordingly if you need to hold conversations or work quietly in the heated space.

Portability and Setup Features

Weight ranges dramatically across torpedo heaters, from 11 pounds for the Remington propane model to nearly 50 pounds for the VEVOR with its large fuel tank. If you need to move the heater frequently, prioritize lighter propane models. For permanent or semi-permanent installations, the weight matters less.

Look for features that improve portability and setup. Carrying handles, wheel kits, and adjustable heat angles all enhance usability. The length of the included hose matters too. The DeWalt F340710 includes a 20-foot hose, which provides significantly more placement flexibility than the standard 10-foot hoses on most models.
