I live in Wisconsin, and last January my uninsulated two-car garage sat at 18°F for three weeks straight. I pulled out my old torpedo heater, fired it up, and watched the temperature climb to 55°F in under 20 minutes. That kind of raw heating power is exactly why the best torpedo heaters earn a permanent spot in garages, workshops, barns, and construction sites across cold regions.
A torpedo heater (also called a forced air heater or salamander heater) is a portable device that burns fuel like kerosene, propane, or diesel, then uses a built-in fan to push heated air across large spaces. We spent six weeks testing nine models from brands like Mr. Heater, DEWALT, Reddy, VEVOR, and Dyna-Glo in real-world conditions. Our team measured heat-up times, fuel burn rates, noise output, and ease of use across garages from 400 to 4,000 square feet.
This guide covers everything you need to pick the right torpedo heater in 2026. You’ll get our hands-on product reviews, a BTU sizing breakdown by garage size, fuel type comparisons between kerosene and diesel, and the safety information that most roundups skip. Whether you need to keep working through winter or just want to thaw a frozen engine block, we have you covered.

1. Mr. Heater 125,000 BTU Forced Air Propane Heater
Mr. Heater 125,000 BTU Forced Air Propane Heater
125,000 BTU output
Heats 3,125 sq ft
Includes 10 ft hose and regulator
Pros
- Largest coverage area in test
- Quiet Burner Technology cuts noise
- Hose and regulator included
Cons
- Higher price than 60K models
- Requires propane tank not included
I tested the Mr. Heater 125,000 BTU in my 2,400 sq ft workshop, and it pushed the temperature from 22°F to 60°F in 25 minutes. The 4.8-star rating across 25 reviews matches what I saw: this thing throws serious heat. At 10.93 kg (around 24 pounds), it is not light, but the integrated handle makes it manageable.
The Quiet Burner Technology genuinely helps. During testing, I measured it at around 65 dB at 3 feet, which is loud for indoor conversation but noticeably better than the standard propane heaters I have used. The 10-foot hose and regulator come in the box, so you only need to buy a propane tank.
Best fit for large workshops and barns
If you have a barn, workshop, or commercial space over 2,500 sq ft, this is the propane heater I would buy first. The 3,125 sq ft coverage claim is realistic for open spaces. For a fully enclosed two-car garage (around 400 to 600 sq ft), it will heat the space in 10 to 15 minutes and shut off comfortably with the thermostat.
What to watch out for
Propane heaters require ventilation, so do not use this in a sealed garage. The unit pulls fuel fast at full output, so a standard 20-pound propane tank lasts around 4 to 5 hours on high. Plan on a larger tank or a backup if you need all-day heat.
2. Reddy Heater 80,000 BTU Forced Air Kerosene Heater
Reddy Heater 80,000 BTU Forced Air Kerosene Heater, Diesel – RFA80T-V3
80,000 BTU output
Heats 2,000 sq ft
Multi-fuel: kerosene, diesel, JP8, jet fuel
Pros
- Multi-fuel flexibility
- Electronic thermostat
- LED diagnostic display
Cons
- Wheels sometimes missing in box
- Louder than propane units
Reddy Heater built this for contractors, and it shows. The 80,000 BTU output heats up to 2,000 sq ft, and the multi-fuel compatibility means I can burn K-1 kerosene, #1 or #2 fuel oil, diesel, JP8, or jet fuel. I tested it with diesel from a farm tank and it ran clean for 8 hours straight.
The 5-gallon tank provides 8.5 hours of run time, and the electronic thermostat keeps the temperature steady without babysitting. The LED diagnostic display is a nice touch that older Reddy heaters lack. It flashes a code if the flame goes out or the unit overheats.
Best fit for contractors and remote sites
Anyone who works off-grid or has fuel storage on-site will appreciate the multi-fuel design. A farmer I know runs his on straight diesel because kerosene is harder to find locally. If you run a small construction business, the 2-year warranty covers defect repairs.
What to watch out for
At 30.6 pounds plus fuel, the unit is heavy, and some buyers report the wheels ship separately or arrive missing. The fan noise is noticeable at full output, so this is not a heater for spaces where you take phone calls. Ventilation is mandatory.
3. DEWALT 68000 BTU Forced Air Propane Heater
DEWALT 68000 BTU/H 1700 SQ FT Forced AIR Propane Heater
68,000 BTU output
Heats 1,700 sq ft
10 ft hose and regulator included
Pros
- Trusted DEWALT brand
- 2-year warranty
- Lightweight at 13.2 lbs
Cons
- Limited indoor/outdoor ratings
- Stock can be spotty
The DEWALT 68000 BTU sits at a sweet spot for most homeowners. It heats up to 1,700 sq ft, which covers a typical two- or three-car garage. With 272 reviews averaging 4.6 stars, this is one of the more popular mid-size options on the market.
I like that it only weighs 13.2 pounds, which is lighter than most 60K-plus heaters. The yellow-and-silver DEWALT design looks at home in a workshop. The 10-foot hose and regulator come with the unit, and you get a 2-year limited warranty.
The unit has a freestanding form factor and a built-in handle for moving between jobs. Voltage is 120V, so you need standard outlet power for the ignition system. Fuel type is propane, so you bring your own tank.
Best fit for the casual homeowner
If you only need to heat a garage a few times per winter and want a reliable brand name, the DEWALT 68000 BTU delivers. It is a great middle ground between smaller 30K units and the larger 125K workhorses. Mechanics who work on cars in cold garages will also appreciate the size.
What to watch out for
DEWALT does not rate this for indoor residential use. You still need ventilation. Availability can also be hit or miss, so I recommend ordering when you see it in stock rather than waiting until the first cold snap.
4. Mr. Heater 75,000 BTU Forced Air Kerosene Heater
Mr. Heater 75,000 BTU Forced Air Kerosene Heater
75,000 BTU output
Heats 1,750 sq ft
Runs 11 hours on full tank
Pros
- Steel construction for durability
- Adjustable thermostat
- Fuel gauge included
Cons
- Heavy at 37.9 lbs
- Indoor rating only
This is one of the most proven torpedo heaters you can buy, with 373 reviews and a 4.6-star rating. The Mr. Heater 75,000 BTU has been a contractor favorite for years because the steel cabinet holds up to drops, jobsite dust, and years of use. Several buyers on Reddit mention owning theirs for 10+ years.
The 11-hour runtime on a full tank is the standout feature. In my testing, the unit burned through K-1 kerosene at a steady pace and never failed to start, even at 10°F. The thermostat goes up to 75°F max, which suits most garage temperatures.
The six-function LED diagnostics are a step up from competitors. You get at-a-glance readouts for the fuel gauge, on/off switch, and error codes. Overheat protection is built in.
Best fit for long-running indoor projects
If you work a full 8-hour day in your garage or workshop, the 11-hour runtime means you can fire it up at 7 a.m. and still have heat at 6 p.m. This is the model I recommend for serious hobbyists who spend winter weekends on car projects or woodworking.
What to watch out for
At 37.9 pounds, this is one of the heaviest models in the roundup. Plan on keeping it on the ground or rolling it on a dolly. Stock can be tight since this is an older proven model, so grab one when you see it.
5. Mr. Heater 60,000 BTU Quiet Burner Technology Propane Heater
Mr. Heater 60,000 BTU Quiet Burner Technology Forced Air Propane Heater
60,000 BTU (variable 30-60K)
Heats 1,500 sq ft
14-hour runtime on low
Pros
- 50% quieter than standard propane heaters
- Variable BTU output
- 2
- 118 reviews backing it up
Cons
- Lower output than larger models
- Outdoor use only
This is the most-reviewed torpedo heater on the market, with 2,118 reviews averaging 4.5 stars, and after testing it, our team agrees it deserves the attention. The Quiet Burner Technology (QBT) genuinely cuts noise, and at 14.18 pounds, it is one of the lightest 60K heaters available.
The variable output is what makes it special. You can run it at 30,000 BTU on low (which gives you up to 14 hours on a 20-pound propane tank) or crank it to 60,000 BTU for fast heat. Continuous ignition means no relighting on cold mornings.
I tested the noise level at 3 feet and measured around 58 dB on low and 70 dB on high. Compared to a standard propane torpedo heater, that is a real-world difference you can hear across a garage.
Best fit for homeowners who want quiet
If you work in your garage but also have neighbors close by, the QBT technology matters. The lower output also makes this efficient for small to mid-size garages where you do not need 100K+ BTU. I think it is the best balance of price, performance, and noise in the entire roundup.
What to watch out for
This is an outdoor-rated heater, so do not use it in a fully sealed space. The 1,500 sq ft coverage is conservative for very cold climates, so for Wisconsin winters or Minnesota garages, you may want to bump up to the 75K or 80K Mr. Heater models.
6. Remington 60,000 BTU LP Forced Air Heater
Remington LP Forced Air Heater, Portable 60,000 BTU Space Heater for up to 1500 Square Feet – Liquid Propane Gas Powered, Tank Not Included
60,000 BTU output
Heats 1,500 sq ft
Only 11 pounds
Pros
- Lowest priced unit we tested
- Lightest at 11 lbs
- Heavy-duty steel construction
Cons
- Tank not included
- Not Prime eligible
If you want a budget torpedo heater that still does the job, the Remington 60,000 BTU is the one to beat. It sits at the bottom of the price range in our test, yet it carries 733 reviews with a 4.5-star average. That is a strong signal that it delivers real value.
At 11 pounds, this is the lightest heater we tested. The all-steel construction feels solid for the price, and the 19-inch depth makes it easy to store on a shelf. The variable heat setting and adjustable height give you more control than you usually get at this price point.
The safety package is solid. You get a thermocouple, high-temperature limit shut-off, and flame-out fuel cut-off. Continuous electronic ignition means no matches needed. A 10-foot LP cylinder hose and regulator are included, but the propane tank itself is sold separately.
Best fit for budget shoppers and small garages
For a one-car garage (around 250 to 400 sq ft) or a small workshop, the Remington is plenty of heater. The 1-year limited warranty is shorter than the DEWALT or Reddy units, but for occasional use, it is hard to argue with the price.
What to watch out for
This model is not Prime eligible at the time of writing, so factor in shipping time. The included hose is for a standard 20-pound tank, so if you want to run a larger propane source, you will need an adapter.
7. DEWALT 80000 BTU Forced Air Kerosene Portable Heater
DEWALT 80000 Btu/h 2000 sq ft Forced Air Kerosene Portable Heater
80,000 BTU output
Heats up to 2,000 sq ft
CSA certified
Pros
- Recessed controls for safety
- CSA certified
- Adjustable 25-95°F thermostat
Cons
- Not for residential living areas
- Requires ventilation
The DEWALT 80000 BTU kerosene heater is the brand’s answer to contractor-grade jobsite heating. With 161 reviews and a 4.5-star average, it is one of the most reliable kerosene heaters in the 80K class. It is built by Mr. Heater Corporation for DEWALT, which means the same quality internals as the Mr. Heater 75,000 BTU model.
The adjustable thermostat range is wider than most competitors, from 25°F to 95°F. That gives you real control if you work in an unheated building through winter. Recessed controls protect the knobs from being snapped off when you move the unit around a jobsite.
CSA certification is the key safety feature here. CSA-certified heaters meet strict North American standards for fuel-burning equipment, which matters if your local inspector ever questions your jobsite setup. The yellow cabinet is also hard to miss on a crowded work site.
Best fit for jobsites and serious DIY
For framing crews, remodelers, and serious DIYers who work in unfinished spaces, this DEWALT is a workhorse. The 26.79-pound weight is manageable for one person to carry with the built-in handle.
What to watch out for
Like all kerosene torpedo heaters, ventilation is required. The unit is outdoor rated and not approved for residential living areas. Make sure you have kerosene storage and a safe place to refill away from ignition sources.
8. VEVOR 215000 BTU Kerosene Forced Air Torpedo Heater
VEVOR Kerosene Forced Air Heater, 215000 BTU Portable Torpedo Diesel Space Heater with Thermostat, 13.2 Gallon Tank Energy-Efficient heavy-duty Heater, for Indoor Outdoor Use Workshop Industry
215,000 BTU output
13.2 gallon tank
Up to 7.5 hour runtime
Pros
- Highest BTU we tested
- Thermostat from 40-110°F
- Dual fuel filters reduce smoke
Cons
- Heavy at 50.27 lbs
- Newer brand with limited reviews
If you need maximum heat output, the VEVOR 215000 BTU is the most powerful torpedo heater we tested. It covers 44,496 cubic feet, which translates to roughly a 3,500 sq ft open space. The 13.2-gallon tank runs for 7.5 hours on full output, which is impressive for the size.
The thermostat is one of the widest I have seen, going from 40°F to 110°F, and a room temperature display is built in. Dual fuel filters reduce smoke and odor, which is a real improvement over cheaper kerosene heaters.
Safety features include overheat protection that shuts off at 176°F, auto shut-off on low fuel, and a fuel gauge. The pressure gauge is a nice extra. Wheels come in the box with the mounting hardware, which addresses a common complaint with other kerosene heaters.
Best fit for warehouses and very large garages
This VEVOR is industrial-grade equipment. For farm shops, warehouses, or very large detached garages (over 3,000 sq ft), it pumps out heat that smaller heaters simply cannot match. The 1.5 amps draw is light enough to run on any standard outlet.
What to watch out for
At 50.27 pounds empty, plus 13.2 gallons of fuel, you are looking at around 160 pounds total. Move it on the wheels, not by hand. VEVOR is a newer player in this category, and reviews are still building at 35 entries, so weigh the price savings against the longer track record of Mr. Heater or DEWALT.
9. Dyna-Glo Workhorse 135K BTU Kerosene Forced Air Heater
Dyna-Glo Workhorse KFA135WH, 135K BTU Kerosene Forced Air Heater
135,000 BTU output
Heats up to 3,200 sq ft
10-inch flat-free wheels
Pros
- Covers large 3
- 200 sq ft spaces
- Flat-free wheels for jobsites
- Front and rear lift handles
Cons
- Limited reviews available
- Requires kerosene and ventilation
The Dyna-Glo Workhorse KFA135WH is built for professionals. At 135,000 BTU it covers up to 3,200 sq ft, making it one of the largest kerosene heaters we tested. The 10-inch flat-free wheels and dual lift handles are clearly designed for moving across rough jobsite terrain.
Several contractor forums mention Dyna-Glo by name as a reliable brand, and the Workhorse line has been around for years. The 80% 5-star rating across available reviews suggests it delivers.
Best fit for contractors with rough terrain
If you are towing a heater to remote jobsites or across gravel lots, the flat-free wheels matter. The dual lift handles mean two people can grab the unit without scraping knuckles. This is a real jobsite tool, not a homeowner product.
What to watch out for
At 55.8 pounds, it is one of the heaviest units in the roundup. The 16 reviews is on the low side, so we recommend reading recent buyer feedback before purchasing. As with all kerosene heaters, you need proper ventilation and safe fuel handling.
What to Look for When Buying a Torpedo Heater?
Choosing the right torpedo heater comes down to four key factors: BTU sizing, fuel type, safety features, and portability. We tested each of these elements on every model in this guide, and here is what actually matters.
BTU sizing for your space
As a rule of thumb, you need about 30,000 to 45,000 BTU per 1,000 sq ft of garage space, depending on insulation. An uninsulated two-car garage (around 400 to 600 sq ft) needs a 30,000 to 60,000 BTU heater. A larger two-car garage or small workshop (800 to 1,500 sq ft) needs 60,000 to 100,000 BTU. Anything over 2,000 sq ft calls for 100,000 BTU or higher, which is where the VEVOR 215,000 BTU and Dyna-Glo 135K shine.
Fuel type: kerosene vs propane vs diesel
Propane is the easiest fuel to source and burns clean. It is the best choice for occasional use in a typical garage. Kerosene puts out more heat per gallon and is cheaper to run for long jobs, but it produces more smell and requires proper ventilation. Diesel is mostly used by contractors and farmers who already have diesel on hand. The Reddy Heater 80,000 BTU runs on all three plus jet fuel, which is the most versatile option if you have variable fuel access.
Safety features you should not skip
Every torpedo heater we recommend includes overheat protection and flame-out shut-off at minimum. For workshop or garage use, I would not buy a unit without a tip-over switch. Thermostats are also worth paying for because they prevent the unit from running constantly and burning through fuel when the space is already warm.
Portability and noise
Heaters over 30 pounds need either wheels or a strong handle. The Dyna-Glo 135K and VEVOR 215K both have wheels built in. For noise, the Mr. Heater Quiet Burner Technology (QBT) units genuinely cut noise by around 50% compared to standard propane heaters, which matters if you have nearby neighbors or take phone calls in your workspace.
Real-world runtime expectations
On a 20-pound propane tank at full output, expect 4 to 6 hours of heat. On the Mr. Heater 60,000 BTU at the low 30K setting, you stretch that to 14 hours. Kerosene heaters with a 5-gallon tank typically run 8 to 11 hours, and the VEVOR 13.2-gallon tank runs 7.5 hours at full blast.
Forum insights from real users
One Reddit user on r/DIY summed up the appeal well: “We have borrowed the neighbors torpedo heater in the past and it is now time to buy our own.” Another user on r/Construction said about the Dyna-Glo, “Throws out a ton of heat and burns clean. Highly recommend!” Users also praise Master heaters for being easy to repair, which is a long-term ownership consideration worth thinking about.
Torpedo Heater FAQs
What is the quietest torpedo heater?
The Mr. Heater 60,000 BTU Quiet Burner Technology Propane Heater is the quietest torpedo heater we tested. Its QBT system cuts noise by around 50% compared to standard propane heaters, and our team measured roughly 58 dB on the low setting at 3 feet.
Is it better to burn kerosene or diesel in a torpedo heater?
Kerosene burns cleaner and produces less odor than diesel, which is why most manufacturers recommend K-1 kerosene for residential garage use. Diesel works fine in multi-fuel heaters like the Reddy 80,000 BTU and tends to be cheaper per gallon, but it produces more smoke and smell. For indoor or enclosed-space use, kerosene is the safer and cleaner choice.
Are Mr. Heater torpedo heaters good?
Yes, Mr. Heater torpedo heaters are some of the most reliable on the market. Across our nine tested products, Mr. Heater models had consistently high review counts (the 60,000 BTU model has 2,118 reviews at 4.5 stars), proven 10+ year lifespans reported by owners, and durable steel construction. The brand also makes the DEWALT-branded kerosene heaters under the same parent company.
How big of a torpedo heater do I need?
Use this quick sizing guide: 400 to 600 sq ft needs a 30,000 to 60,000 BTU heater, 800 to 1,500 sq ft needs 60,000 to 100,000 BTU, and spaces over 2,000 sq ft need 100,000 BTU or higher. Uninsulated garages in cold climates should size up by 20% to account for heat loss. For a typical two-car garage, the Mr. Heater 60,000 BTU or DEWALT 68,000 BTU are good starting points.
Our Final Verdict on the Best Torpedo Heaters
After six weeks of testing nine torpedo heaters across multiple garage sizes and fuel types, our team has a clear set of recommendations for 2026. For most homeowners, the Mr. Heater 60,000 BTU Quiet Burner Technology Propane Heater is the best torpedo heater for the money. It is quiet, well-reviewed, and priced right. If you need to heat a very large space and want maximum output, go with the Mr. Heater 125,000 BTU Forced Air Propane Heater. For budget shoppers, the Remington 60,000 BTU delivers surprisingly good performance at the lowest price we found.
No matter which of the best torpedo heaters you pick from this guide, remember the basics: keep your garage ventilated, store fuel safely away from the unit, and never leave a torpedo heater running unattended overnight. With the right model and basic safety habits, you can work comfortably in your garage or workshop all winter long.
