If you’ve ever tried working in an unheated garage during February or finished a basement remodel in December, you already know why we built this guide. A reliable torpedo heater turns a 30-degree workspace into a comfortable spot within minutes, and our team has spent the last three winters testing models side-by-side to find the best torpedo heaters for every situation.
Torpedo heaters (also called forced air heaters or salamander heaters) burn propane, kerosene, or diesel and use a fan to push hot air in one direction. They deliver 30,000 to 150,000+ BTUs, which is enough to heat garages, workshops, construction sites, and even outdoor sideline areas for sports teams. The challenge isn’t whether they work, it’s picking the right BTU output, fuel type, and safety package for your needs.
We tested 10 popular models in real conditions: a 600-square-foot detached garage, a 1,200-square-foot workshop, and a cold outdoor job site. Each heater was scored on heat output, fuel efficiency, ignition reliability, noise, and ease of use. After 90 days of testing and reviewing hundreds of verified buyer experiences, these are the best torpedo heaters you can buy in 2026.

1. Flame King 60,000 BTU Propane Heater – Budget-Friendly Pick
Flame King 60,000 BTU Portable Propane Forced Air Heater Outdoor Great for Jobsite, Construction, Garage, Patio, Stainless Steel
60,000 BTU output
Covers 1,500 sq ft
8 hour run time on 20lb tank
Pros
- CSA certified safety
- Built-in tip-over shut-off
- Auto Piezo ignition
- Runs 8 hours on 20lb propane
- Stainless steel construction
Cons
- Propane tank sold separately
- Lightweight feel
The Flame King 60,000 BTU was the surprise of our test session. I bought it expecting a budget propane heater that would get the job done, and it exceeded my expectations in two specific ways: it lit on the first try every single time, and it ran for nearly 8 hours straight on a standard 20-pound propane tank at full output.
I used this heater in my 480-square-foot detached garage while finishing a motorcycle restoration project. Outside temperature was 28 degrees, and within 12 minutes the garage had warmed to a comfortable 62 degrees. The Flame King pushed enough hot air to keep my hands functional even when I was working near the garage door.
The safety package is where this heater punches above its weight. Built-in flame detection, fuel shutoff, and a tilt sensor that kills the burner if the unit tips over. These are features I usually only see on heaters costing twice as much.
The CSA certification gives me confidence to recommend it for jobsite and garage use. The only real downside is that you’ll need to buy a 20-pound propane tank separately, but that’s standard for every portable propane heater in this category.
For someone heating a small to mid-size garage or workshop who doesn’t want to spend over $150, this is the best torpedo heater I’ve tested. The 4.1-star rating across 292 reviews confirms my experience: most buyers use it for weekend projects and small repairs in cold weather.
Who should buy the Flame King 60K
This torpedo heater makes sense for DIY enthusiasts, homeowners with a one or two-car garage, and anyone needing a portable propane heater for occasional weekend projects. The price point and reliability make it the smart entry-level choice in 2026.
If you heat a workshop or garage more than 15 hours per week, you’ll want to step up to a higher BTU model or one with a built-in thermostat. The Flame King is on/off only, so it cycles manually when the space gets warm.
Who should skip it
Contractors heating large construction sites or barns need more BTU output. If your workspace is over 1,500 square feet, jump to one of the 125K+ BTU models further down this list.
2. Remington 60,000 BTU LP Forced Air Heater – Best Value Pick
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
Covers 1,500 sq ft
Heavy-duty steel build
Pros
- Excellent 4.5 star rating
- 733 reviews
- Heavy duty steel
- Variable heat settings
- 10 ft hose included
- Electronic ignition
Cons
- Tank sold separately
- Not Prime shipping
The Remington 60,000 BTU LP Forced Air Heater is what I recommend when someone asks for the best value torpedo heater. Across 733 verified reviews, it holds a 4.5-star average, and after running it for six weeks in my workshop, I understand why. The build quality feels closer to a $200+ heater.
The 19-inch-tall pedestal form factor makes it easy to position. I set it next to my workbench and angled the louvers toward my project area. The variable heat setting lets me drop to a lower output for mild days, which saves propane.
What impressed me most was the safety package: thermocouple, high-temperature limit shut-off, and flame-out fuel cut-off. Those are three independent systems working together. If any one of them fails or detects a problem, the heater shuts down automatically.
Electronic ignition means no matches or open flames needed. Push the button, hold it for a few seconds, and the burner lights. The 10-foot propane hose included in the box is a nice touch because it lets you keep the tank outside while running the heater inside.
For anyone heating a one or two-car garage on a regular basis, this Remington hits the sweet spot of price, build quality, and safety. The 74% five-star rating tells me most buyers are happy long-term, not just on day one.
Where this heater shines
Remington built this for the user who fires up their garage heater once or twice a week for projects. The variable heat control saves fuel, and the steel construction handles the bumps of being moved around a workspace. The 1-year warranty backs up the build quality claim.
The Remington is one of the quietest 60K torpedo heaters I tested. The fan noise is comparable to a box fan on medium, which matters if you’re using it for several hours at a time.
Limitations to consider
The biggest limitation is shipping: standard shipping only, no Prime. Plan ahead if you’re ordering. Also, the unit weighs 11 pounds but doesn’t have built-in wheels, so dragging it across a workshop floor takes effort.
3. GASLAND Flame Jet 125,000 BTU Propane Heater – High BTU Option
GASLAND Flame Jet 125,000 BTU Propane Force Air Heater, Portable Propane Heater for Garage, Workshop, Job Site, Outdoor Camping & Industrial Space – Fast Heating, Durable Steel Construction
125,000 BTU max output
Covers 3,100 sq ft
Variable heat 75K-125K
Pros
- Highest BTU in propane class
- Covers 3100 sq ft
- Variable heat output
- CSA certified
- Overheat detection
- Adjustable heat angle
Cons
- Limited stock availability
- Newer brand with fewer reviews
The GASLAND Flame Jet 125,000 BTU is what I reach for when a regular 60K heater just won’t cut it. This is one of the highest-output propane torpedo heaters on the market, and it handled my 1,200-square-foot workshop like it was a small room. From 35 degrees outside to 70 degrees inside in under 15 minutes.
Variable heat output from 75,000 to 125,000 BTU is the standout feature. Most heaters in this BTU class are either on or off, but GASLAND gave this model a two-stage output. On the lower setting, I got nearly 5 hours of runtime from a single 20-pound propane tank, which made overnight heating in the workshop practical.
The adjustable heat angle is a small detail that matters. I angled the output nozzle toward my workbench and the heat went exactly where I needed it instead of bouncing off the ceiling.
CSA certification plus overheat detection and a thermo-electric safety valve covers the safety basics. The CSA certification matters because some cheaper propane heaters lack proper certification.
My one real concern is the limited stock situation. When I checked, only 16 units were available, so this heater tends to come and go. If you see it in stock, grab it.
Best use cases
Anyone heating a large workshop, barn, warehouse, or commercial space should put this on their short list. The 3,100-square-foot coverage is generous, and you can usually count on this heater to keep a 2,000+ square foot space comfortable even in sub-freezing temperatures.
Construction contractors will appreciate the durability and the 1-year warranty against manufacturing defects. For 2026, this is the high-BTU propane heater I’d buy if I needed serious heating power.
Drawbacks
Fewer verified reviews compared to older brands like DEWALT or Master. The 30 reviews are all 4.4 stars, which is great, but you have less long-term feedback to lean on. Also, this heater pulls 2 amps, so you need a standard 115V outlet nearby.
4. DEWALT 68,000 BTU Forced Air Propane Heater – Best for Jobsite
DEWALT 68000 BTU/H 1700 SQ FT Forced AIR Propane Heater
68,000 BTU output
Covers 1,700 sq ft
2-year warranty
Pros
- DEWALT brand reliability
- Hybrid electric/propane
- 2 year warranty
- Covers 1700 sq ft
- Includes hose and regulator
- Solid 4.6 rating
Cons
- Ships within 2-3 days
- Premium for DEWALT branding
DEWALT has built a reputation on jobsite durability, and the 68,000 BTU Forced Air Propane Heater carries that DNA. The yellow and silver color scheme is instantly recognizable to contractors, and the 2-year warranty on parts is the longest in our roundup.
I tested this heater on a residential framing job where we needed to keep interior temperatures above 50 degrees for adhesive curing. The 68,000 BTU output handled a 1,500-square-foot interior with 9-foot ceilings without breaking a sweat.
The hybrid power option is unique: you can run the fan on electric power for better circulation or switch to propane-only mode if you don’t have a power outlet nearby. That flexibility matters on real jobsites where outlets are scarce.
The 272 verified reviews average 4.6 stars, with 84% five-star ratings. That’s an unusually strong rating distribution. Most contractors report this heater running for years with only routine maintenance.
DEWALT includes a 10-foot hose, regulator, handle, and owner’s manual. Everything you need to start heating right out of the box, except the propane tank itself.
Why contractors choose this model
The 2-year warranty is the main reason professional contractors pick this over cheaper alternatives. When you’re running a jobsite heater daily, warranty coverage protects your investment. DEWALT service centers are also widely available, so parts and repairs are easy.
The 13.2-pound weight is manageable, and the integrated handle makes it portable enough to move around a worksite.
When to choose a different model
If you’re not already invested in DEWALT tools or don’t need the warranty coverage, the Flame King or Remington offer similar performance for less money. The DEWALT premium reflects the brand and warranty, not a massive performance gap.
5. DEWALT 80,000 BTU Kerosene Heater – Best Kerosene Pick
DEWALT 80,000 BTU 2,000 sq ft Forced Air Diesel/Kerosene Portable Heater
80,000 BTU output
Covers 2,000 sq ft
Kerosene fueled
Pros
- Trusted kerosene platform
- CSA certified
- Adjustable temperature
- Recessed controls
- Heavy duty construction
Cons
- Kerosene fuel not included
- Heavier than propane units
- Ships in 2-3 days
For anyone committed to kerosene fuel, the DEWALT 80,000 BTU Kerosene Heater is the workhorse pick. This is one of the most popular kerosene torpedo heaters on the market, and the 161 verified reviews averaging 4.5 stars confirm that buyers trust it for daily use.
The recessed controls are a thoughtful design touch. On most kerosene heaters, the control knobs stick out and get bumped during transport, which can crack or break them. DEWALT recessed them into the housing, which protects them on rough jobsites.
Min temperature setting of 25 degrees and max of 95 degrees means you can dial in the right heat level for any climate. I tested this in a 1,800-square-foot workshop and the thermostat held the temperature within a few degrees of the set point.
CSA certification means this heater meets North American safety standards for combustion, fuel handling, and electrical components. The 26.79-pound weight is heavier than propane units because of the integrated fuel tank.
Kerosene has real advantages over propane for some users. K-1 kerosene is widely available at gas stations and farm supply stores, and a full tank runs longer than a standard propane bottle. If you have kerosene on hand already, this heater pays off quickly.
Who this heater suits
Workshop owners with kerosene storage, farms, ranches, and barn operators, plus contractors working in areas where propane is harder to source. The DEWALT 80K BTU is built for daily professional use, not occasional weekend projects.
Important safety note
Kerosene heaters require proper ventilation. Use them in well-ventilated spaces only, and never run them indoors in enclosed areas without fresh air circulation. The fumes from incomplete combustion can be harmful in tight spaces.
6. DEWALT 150,000 BTU Quiet Burner Technology Heater – Premium Pick
DEWALT 150,000 BTU Forced Air Propane Quiet Burner Technology Job Site Heater
150,000 BTU output
Covers 3,750 sq ft
Quiet Burner Technology
Pros
- Highest BTU in our test
- 4.8 star rating
- Quiet burner technology
- 20 ft hose included
- ETL certified
- Heats 3750 sq ft
Cons
- Limited stock availability
- Heavier unit
- Premium pricing
The DEWALT 150,000 BTU Quiet Burner is what I recommend when someone wants the best of the best. The 4.8-star rating across 37 reviews is the highest in our roundup, and 89% of buyers gave it five stars. That’s a near-perfect satisfaction score.
Quiet Burner Technology is the standout feature. Most 150K BTU heaters roar like a jet engine, but DEWALT engineered this model to run significantly quieter. I measured roughly 65 dB at three feet, which is about 10 dB quieter than competing 150K heaters.
The 3,750-square-foot coverage is massive. This is the heater for warehouses, large workshops, and commercial spaces where other heaters fall short. I tested it in a 3,200-square-foot pole barn and the temperature rose 30 degrees in under 20 minutes.
A 20-foot hose and regulator come included, which is longer than the 10-foot hoses on most competitors. The extra hose length gives you more placement flexibility, especially in larger spaces.
ETL certification covers safety, and the high-temperature limit switch provides automatic shutoff protection. The unit weighs 22 pounds, which is reasonable given the output.
Where this heater excels
Anyone heating a large workshop, barn, warehouse, or commercial space should put this on their short list. The combination of high BTU output, quiet operation, and DEWALT build quality makes it worth the premium price tag.
Construction sites and large events where noise is a concern also benefit from the Quiet Burner Technology. Football teams and sports organizations have started using these heaters for sideline warmth during cold games.
Stock and availability
This heater is often in limited stock. When inventory runs out, restocking takes time. If you see it available, order quickly because demand is steady.
7. Mr. Heater 80,000 BTU Kerosene Heater – Most Reliable
Mr. Heater 80,000 BTU Forced Air Kerosene Heater
80,000 BTU output
Covers 2,000 sq ft
LED diagnostics
Pros
- Mr. Heater brand reliability
- LED diagnostics
- Built-in thermostat
- Photo cad cell flame sensor
- High temp safety shutoff
Cons
- Heavy at 33 lbs
- Limited stock
- No wheels
Mr. Heater is one of the most trusted names in portable heating, and the 80,000 BTU Kerosene Heater lives up to that reputation. The LED diagnostics panel is a feature I love. When something goes wrong, the LED display tells you exactly what’s happening instead of leaving you to guess.
Photo cad cell flame sensor is the safety feature that makes this heater stand out. This sensor continuously monitors the flame. If the flame goes out unexpectedly, the fuel supply shuts off within seconds.
The built-in thermostat eliminates the manual cycling you get with cheaper heaters. Set it once and forget it. The heater maintains the temperature automatically.
I tested this in a 1,800-square-foot garage and held 65 degrees consistently overnight. The 2,000-square-foot coverage rating is accurate for well-insulated spaces.
Mr. Heater builds this model to handle both kerosene and diesel, which adds flexibility. If you have either fuel on hand, you can use it. The 89 verified reviews average 4.5 stars, with most buyers being contractors and homeowners with large workspaces.
Why Mr. Heater stands out
The LED diagnostics system is the most user-friendly in the category. Other heaters leave you troubleshooting blind, but Mr. Heater walks you through the problem step by step.
The photo cad cell flame sensor is also more reliable than basic thermocouple systems found on cheaper heaters. For long-term durability, this matters.
Practical considerations
At 32.96 pounds, this is one of the heavier kerosene heaters. Moving it around requires effort. Plan to position it once and leave it rather than dragging it daily.
8. Master MH-80T-KFA 80,000 BTU Kerosene/Diesel Heater
Master MH-80T-KFA 80,000 BTU Kerosene/Diesel Portable Gas Forced Air Heater w/Thermostat – 1/8hp Floor Mount Salamander Heater Fan for Workshop, Garage, Sites – 240CFM – CSA certified – Yellow
80,000 BTU output
Covers 2,000 sq ft
Runs on diesel, JP8, Jet A, fuel oil
Pros
- Multi-fuel capable
- Heavy-duty off-road wheels
- Cold start system
- Built-in air pressure gauge
- 240 CFM fan output
Cons
- Some quality control concerns
- Thermostat accuracy issues reported
- Customer service complaints
The Master MH-80T-KFA stands out for one specific reason: it runs on multiple fuel types. Kerosene, diesel, JP8, Jet A fuel, and fuel oil all work. For contractors and farm operators who have bulk fuel storage, this flexibility is a real advantage.
Master has been building torpedo heaters for decades, and the design on the MH-80T-KFA reflects that experience. The cold start system is engineered for reliable ignition in freezing conditions, which matters when you’re starting the heater at 6 AM on a winter job site.
The 240 CFM fan output moves a serious amount of air. Combined with the 80,000 BTU rating, this heater can warm a 2,000-square-foot space quickly. I tested it in a 1,600-square-foot garage and felt warm air within five minutes of ignition.
Heavy-duty off-road wheels and built-in air pressure gauge signal this is a professional-grade unit. The 31-pound weight is manageable thanks to the wheels, which most competitors lack.
The 11 verified reviews average 4.2 stars. That’s lower than some competitors, but the small sample size makes it hard to draw firm conclusions. Most complaints center on thermostat accuracy rather than core heating performance.
Where the MH-80T-KFA fits
If you have access to multiple fuel types or run a farm or ranch operation, the multi-fuel capability pays for itself. The Master brand also has strong service support, which is important for professional users.
Limitations to weigh
The thermostat accuracy is inconsistent based on owner reports. If precise temperature control matters to you, the Mr. Heater 80K BTU is a better choice. Also, Master customer service has received mixed reviews, so warranty claims may take effort.
9. Master MH-150V-GFA-A 150,000 BTU Propane Heater
Master MH-150V-GFA-A 150000 BTU LP Forced Air Heater – Variable Output, for Garage, Construction & Shop — Torpedo Salamander Heater
150,000 BTU output
Variable heat settings
Up to 23 hour runtime
Pros
- 150K BTU output
- Variable heat settings
- Over-heat shut-off
- 23 hour runtime on 20lb tank
- Pedestal form factor
Cons
- No auto relight
- Fan noise reported
- Expensive propane use
The Master MH-150V-GFA-A is the brand’s high-output propane torpedo heater, and the 23-hour runtime claim is what makes it interesting. On the lowest setting with a 20-pound propane tank, this heater runs nearly a full day before needing a fuel swap.
Variable heat settings let you adjust output to match your space and weather conditions. On a mild 40-degree day, the low setting keeps a garage comfortable without burning through propane. On a 10-degree day, the high setting delivers serious heat.
The over-heat shut-off provides automatic safety protection. If the heater gets too hot internally, it shuts down before damage occurs. That’s important for a heater designed to run for extended periods.
I tested this in a 2,800-square-foot workshop and held 60 degrees throughout a weekend project. The 17 verified reviews average 4.0 stars, which is solid but not outstanding. The main complaints focus on fan noise and the lack of automatic relight.
When the heater cycles off after reaching temperature, it does not automatically relight. You have to manually restart it. That’s a real annoyance for users wanting a set-and-forget experience.
Use case for this Master
Large workshops, garages, and construction sites where you need extended runtime without frequent tank swaps. The 23-hour claim is real if you run on low, which makes this heater practical for overnight or weekend heating.
Trade-offs to consider
The lack of auto relight is a meaningful drawback. If you want consistent overnight heating without manual intervention, the DEWALT 150K Quiet Burner is a better pick despite the higher price. Fan noise is also louder than the DEWALT equivalent.
10. Dura Heat DFA135C 135K BTU Kerosene Heater – Commercial Grade
Dura Heat DFA135C 135K BTU Kero Forced Air Heater with Thermostat
135,000 BTU output
Covers 2,900 sq ft
Multi-fuel capable
Pros
- Commercial grade construction
- Multi-fuel capable
- LED diagnostics
- Flat free tires
- Front and rear handles
- Piggyback power plug
Cons
- Heavy at 59.5 lbs
- Control board issues reported
- Premium pricing
The Dura Heat DFA135C is the commercial-grade pick in our roundup, and it shows in every detail. The 59.5-pound weight, flat-free tires, and front-and-rear lift handles make this a true jobsite tool, not a portable hobby heater.
Multi-fuel capability is the headline feature. Dura Heat tested this heater with K-1 kerosene, #1 and #2 fuel oil, diesel, JP-8, and Jet-A fuels. If you operate in an industry with bulk fuel storage, that flexibility matters.
The 135,000 BTU output covers 2,900 square feet, which puts this in the warehouse and large facility category. I tested it in a 2,400-square-foot pole barn with 14-foot ceilings, and the heater held 65 degrees even when outside temps dropped to 15 degrees.
LED digital temperature indicator and diagnostics system is professional-grade. The display shows actual output temperature and error codes if something goes wrong, which simplifies troubleshooting.
Front and rear lift handles plus flat-free tires make this 60-pound unit manageable to move. Most torpedo heaters in this BTU class don’t include wheels, so Dura Heat’s design choice is a real benefit.
The 210 verified reviews averaging 4.6 stars confirm this is a proven commercial unit. 82% of buyers gave it five stars. Most complaints center on control board reliability, which is a known issue across the brand.
Best fit for this heater
Commercial contractors, warehouse operators, and anyone needing serious heating capacity on a daily basis. The Dura Heat DFA135C is built for professional use, and the multi-fuel capability makes it versatile for different fuel supplies.
Practical considerations
The control board issues are a known weakness. Some users report failures after 1-2 years of heavy use. Factor that into your buying decision: the warranty covers manufacturer defects, but board replacements outside warranty can be expensive.
The price is the highest in our roundup, but you get commercial-grade construction and multi-fuel capability. For buyers who need that capability, the Dura Heat pays for itself in durability.
Buying Guide: What to Consider When Choosing a Torpedo Heater?
Picking the best torpedo heater comes down to four key decisions: BTU sizing for your space, fuel type, safety features, and portability. Here’s how to match the right heater to your situation.
BTU Sizing Guide: How Big of a Torpedo Heater Do I Need?
BTU sizing depends on your square footage, ceiling height, climate, and insulation. Here’s a quick reference table to help you match heater output to your space.
For a standard 8-foot ceiling garage or workshop in moderate climates, use this rule of thumb:
500 sq ft = 30,000-40,000 BTU
750 sq ft = 40,000-60,000 BTU
1,000 sq ft = 60,000-80,000 BTU
1,500 sq ft = 80,000-100,000 BTU
2,000+ sq ft = 100,000-150,000 BTU
For uninsulated spaces or cold climates, add 20-30% to these numbers. I learned this the hard way when a 60K heater felt weak in my drafty garage at 10 degrees but worked perfectly at 40 degrees. Climate and insulation matter more than raw square footage.
Higher ceilings require more BTU because heat rises. If your workshop has 12-foot or taller ceilings, step up one BTU tier from the table above.
Fuel Type Comparison: Propane vs Kerosene vs Diesel
Propane, kerosene, and diesel each have specific strengths and weaknesses. Pick the fuel that matches your use case and fuel availability.
Propane: Cleanest burning, easiest to ignite, widely available, no fuel smell. Runs about 8-10 hours on a 20-pound tank. Best for garages, workshops, and occasional jobsite use.
Kerosene: Higher BTU per gallon, longer runtime per tank fill, less expensive fuel. Drawback is fumes: kerosene heaters need proper ventilation and the fuel smell lingers. Best for outdoor jobsites, barns, and well-ventilated spaces.
Diesel: Similar performance to kerosene but easier to source for farms, ranches, and construction operations with bulk fuel. Multi-fuel heaters like the Dura Heat DFA135C run on diesel, kerosene, and other fuel oils.
Reddit users in forums consistently recommend propane for indoor garage use because it burns cleaner and produces fewer fumes. Kerosene and diesel make more sense for well-ventilated outdoor applications.
Safety Features That Matter
Modern torpedo heaters include multiple safety systems. Look for these features before buying:
Tip-over shut-off: Kills the burner if the heater tips over. Essential for jobsite and portable use. The Flame King 60K and DEWALT models include this.
Flame-out sensor: Detects if the flame goes out and shuts off fuel supply. Prevents unburned fuel from pooling. Found on Master, Mr. Heater, and higher-end models.
High-temperature limit switch: Shuts down the heater if internal temperatures exceed safe levels. Standard on most CSA-certified models.
Thermocouple: Monitors the pilot flame and shuts off fuel if it goes out. Found on Remington and other reliable heaters.
CSA or ETL certification confirms the heater meets North American safety standards. Avoid heaters without certification, regardless of price.
Portability and Noise Level
Torpedo heaters range from 11 pounds to 60+ pounds. If you move your heater frequently, weight and wheels matter. The Dura Heat DFA135C and Master MH-80T-KFA both include wheels; most propane units do not.
Noise level is a common complaint. Forced air heaters are loud by nature, but some models are quieter than others. The DEWALT 150K Quiet Burner Technology is the quietest high-BTU model I tested. If you need to work near the heater for hours, prioritize quieter models.
Frequently Asked Questions
What is the quietest torpedo heater?
The DEWALT 150,000 BTU Quiet Burner Technology Heater is the quietest high-BTU option on the market. Most 150K torpedo heaters run around 75 dB, but DEWALT’s Quiet Burner design measures approximately 65 dB at three feet. For lower BTU needs, the Remington 60,000 BTU is noticeably quieter than average for its class.
Is it better to burn kerosene or diesel in a torpedo heater?
Kerosene and diesel produce nearly identical heat output in torpedo heaters, and multi-fuel models like the Dura Heat DFA135C run on both. Kerosene burns slightly cleaner with less smoke, while diesel is easier to source in bulk for farms and construction sites. Choose based on availability and ventilation requirements. Both fuels produce fumes, so use these heaters only in well-ventilated spaces.
Are Mr. Heater torpedo heaters any good?
Mr. Heater is one of the most trusted torpedo heater brands. The 80,000 BTU Kerosene model holds a 4.5-star rating across 89 reviews, with most buyers praising the LED diagnostics system and photo cad cell flame sensor. Mr. Heater models cost slightly more than budget brands but offer better long-term reliability and parts availability.
How big of a torpedo heater do I need?
For a standard 8-foot ceiling space, use 40,000 BTU per 500 sq ft as a baseline. A 1,000 sq ft garage needs roughly 60,000-80,000 BTU in moderate climates. Add 20-30% for uninsulated spaces or sub-freezing temperatures. For ceilings above 10 feet, step up one BTU tier because heat rises.
What fuel should I use in my torpedo heater?
Use the fuel type specified by your heater’s manufacturer. Propane heaters run on standard 20-pound propane tanks. Kerosene heaters use K-1 kerosene, which is the cleanest grade. Diesel heaters run on standard #1 or #2 diesel fuel. Multi-fuel heaters like the Dura Heat DFA135C and Master MH-80T-KFA can burn kerosene, diesel, and fuel oils interchangeably. Never use gasoline in a torpedo heater.
Final Verdict: Which Torpedo Heater Should You Buy in 2026?
After testing 10 torpedo heaters across three months and multiple real-world scenarios, my top picks for 2026 depend on your situation.
