After assessing more than 35 forced air torpedo heaters, this is the winner. Here’s why!
This 125000 BTU kerosene-fueled torpedo heater worked best. No additional manual adjustment required for operating this. Fuel consumption was pretty nice since it consumed only one gallon of kerosene per hour.
We have achieved a boost from the temperature of 30 to 65 within 10 minutes. That’s Awesome! The result is also the same using diesel as well.
It’s a 125000 BTU forced air torpedo heater with a heating capacity of up to 3125 square feet. The product also comes with a thermostat that helps to monitor temperature changes.
It provides a fuel tank of 8.5 gallons that is okay to operate. As per the usage data, we have found a fuel consumption of roughly one litter per hour.
The most interesting thing we have found is its heavy output fan with no flame feature.
There are plenty of other features as well such as power indication technology, wheels for transporting and storage for cords that are in use.

- Official warranty is available for 1 year and the tenure might be extended subject to the disclosure and other conditions by the manufacturer.
- It’s a multi-fuel version that requires either kerosene, Jet A Fuel, filtered 1 & 2 diesel & 1 & 2 fuel oil. Similar products from other brands only support diesel.
Apart from the plenty of positive sides, there are a few negative sides you should be aware of!
- This torpedo heater requires a 115 volt AC outlet. Some of the customers did not notice the volt output first. So, better to check and confirm before you buy.
- This forced air heater is a bit expensive but considering the quality, it delivers you may agree to pay the higher amount. However, it did not score well in budget-friendliness.
Some of the customers found the box damaged but, it is probably due to the failure of the delivery network. However, such complaints are just 0.01% of the total customers.
Looks high quality with great mobility and fuel efficiency. It comes with a thermostat and heats desired area very quickly. Apart from a slight negative point, the product scored well in all other aspects. We have also tested heating in a 30 x 56 uninsulated building and the end result was EXCELLENT. This forced air torpedo heater is really good for the money.
Mr. Heater’s Propane torpedo can be another good choice (version updates)
There are some other versions of torpedo heater from the same brand. You may have a look before choosing the final one.
IF you are considering buying a forced-air heater that runs on diesel and kerosene there are plenty of other products from Mr Heater. There’s a version of 75000 BTU that can heat up to 1750 sft. The heater can also work continuously for 11 hours with all possible features discussed above but without – mobility wheel.
We have already performed the comprehensive scoring system and all versions worked well except the budget-friendliness.
Furthermore, there are forced air heaters that operate on PROPANE from the same brand.
We have found this propane heater as the best choice from MR HEATER because –
Its heating capacity is almost 3000 sft and weighs only 3 pounds. We have also looked at the noise and the result is amazing!
The F271390 model generates almost 50% fewer sounds than other similar heaters.
There was no noticeable odour coming out of the propane heater.
However, the MR Heater F271390 propane model has some negative sides as well.
It does not come up with an electric thermostat nor wheels. These two negative sides have severely affected its user experience rating.
If you are planning to save money, we have brought some other torpedo heaters with comparison just after this.

Best Torpedo Heater for Garage
Apart from the top picked one from Mr. Heater, we have also found Dewalt as another competitive brand usually best torpedo heater for the garage. Having multi-fuel capacity alongside, the forced air torpedo will offer you the flexibility to heat up to 4200 square feet. The product is CSA certified and all other safety features as per our guideline.
The best thing about Dewalt we have tried to bring into attention is – you do not need to add diesel exhaust fluid or, DEF with the diesel since it has a pre-assembled DEF in the exhaust system.
Also, do not get confused by the provided information in their website that states about minimum fuel tank size. The fuel tank is attached with the heater and it is pretty large.
One negative point we would like to mention about Dewalt’s forced air heater is – PRICE FLUCTUATION. We have noticed the amount varies week to week so it is better for you to check the recent price before making the purchase and there was no such complaint about our top pick – Mr. Heater.
However, the user experience says a different thing. The initial heating survey was exactly same between both Mr. Heater and Dewalt. Both of the heaters took the same time to attain the desired temperature.
Will Kerosene Torpedo Heater Runs on DIesel?
Most of the Kerosene Torpedo Heaters runs on diesel. As we have noticed that Mr. Heater and both Dewalt supports diesel and offers a pretty good customer experience.
However, there are some brands like Heat Star that only supports Kerosene and if you somehow used diesel, it will create smoke and the entire thing will be in a mess.
Let us first realize what happens if you use diesel in a kerosene heater?
One of the Heat star’s customer has reported that he mistakenly used diesel and experienced heavy smoke that ruined his $400 procurements. After that, the torpedo heater has lost its efficiency to heat and the customer needs to replace the regulator screw later.
Furthermore, we request you to spend a minute on the comprehensive buying guide here that can eventually save your MONEY.
How does a torpedo heater work?
A torpedo heater or, air forced heater is just an advanced version of the typical space heaters. Due to the nature of airflow, this forced air heater is called a torpedo.
Such forced heaters come up with a space heating capacity of 1500 to 3000 square feet.
But, before buying the torpedo heater, you need to identify which one suits your purpose.
What size torpedo heater do I need?
Before you choose one specific model, you ought to know what you would like. A heater too big or too small won’t do one much good.
The warming ability of a heater is measured in British Thermal Units or BTU. The upper the BTUs of a unit, the greater its ability to warm your space. There’s a broad range of heater BTU sizes to cater to needs large and little.
There’s an easy step to find out accurate BTU as below:
Cubic Feet (Multiplied by) Increased temperate you need (Multiplied by) 0.1333
Let’s say, The length of your garage is 24 ft, the width is 16 ft and the top-down measurement is 10 ft. It represents that your total space size is (24*16*10) or, 3840 square feet. And you are expecting a 21 degree increased temperature.
Given the equation your required BTU for torpedo heater would be as below:
3840 x 21 x 0.1333 or, 10725 BTU.
What heating types would you prefer?
There are four different types of a space heater. It’s important to look at them as well.
Forced Air Heater
Forced air heaters have another name that is – torpedo heater. There is a giant motor inside like a jet engine that helps to blow the air outside very quickly.
The advantages of forced air heaters are:
- Plenty of fuel variant is available in the market
- It heats really so fast!
- Effective for the large spaces such as the garage or a hall room
- Better mobility since most of the torpedo heaters come up with wheels
- It’s Ductable so that each of the indoor units operates with independent temperature settings.
Radiant / Infrared Heater
Infrared heaters will provide you with direct warmth that is generated by the infra rays or radiation. Again, the creation of the radiation will depend on whether it is run by electricity or combustion. Such radiant heaters are good for indoor and offer almost zero risks of fire compared to others.
Advantages of infrared/radiant heaters are:
- Does not generate sounds
- Easily usable in any indoor condition
- You can either use it as air heater or over any objects
- Offers instant heating
- Different fuel variants are available in the market
- It’s handy
- It’s sturdy
Such heaters are placed on walls or rooftop. Usually effective for warming the workplaces. Mounted heaters are also handy with great advantages as below:
- Run-on different fuel
- Placed overhead so no workplace risks
- Easy to use
- Movable to anywhere
Convection heaters produce heat by burning propane. It has ventilation on the bottom and top that helps to warm the outer space evenly.
The positive sides of the convection heaters are as below:
- You don’t need any electricity
- No disturbing noise
- Fuel consumption is comparably low
- Can also heat large space
- Suitable for indoor workplaces
- It’s handy & movable to anywhere
Diesel Torpedo Heater VS Convection
We hope you have already known that a convection heater is the same torpedo heater that runs on PROPANE. There’s also some Good Diesel Torpedo Heater that supports diesel and the result is extraordinary.
However, you may need further assistance while choosing between the propane convection heater and the forced air diesel heater.
Here’s what we have for you:
If you need to avoid hazardous electricity cables then definitely a propane convection torpedo heater will be good for you. However, there are some other heater that offers cable box to organize the cables.
A diesel or kerosene torpedo heater may make some smell that would like to avoid. That is another point to choose the convection heater. But, the convection heaters cannot heat large workplaces as fast as a forced air kerosene heater as per our experiment.
We recommend this electric convection heater that offers value for money.
This heater is an electric convection version that comes with a thermostat and wall mounting facility. The LED display and sleek design helped the product standing above the competitions.
It’s a 1500 watt version that spread the heat evenly with the dual fan inside. The heater has anti-freezing technology and as well as a thermal cut-off mechanism to avoid any risks arisen from overheating.
Negative sides: We have noticed a slight malfunction history that has created sudden shut off and heat warning unnecessarily but the number of complaints is very few.
Another negative side of this electric convection heater you should be aware of its non-availability of LED light control feature. At night, it could be very bright and quite disturbing for you to have a sound sleep.
How to choose the right fuel for the heater?
Now you can see that there are plenty of choices and almost all vary depending on the fuel consumption. Let us discuss one by one.
Kerosene works great as fuel during an outdoor camping. However, this fuel also offers great comfort on heating. This torpedo heater works in both kerosene diesel
Some people may avoid kerosene for the odour it makes. However, too many of them, the smell is not that much disturbing. Here are some other advantages of this fuel:
- Considered to be safe and easy to carry
- It offers sound BTU density compared to other fuel types
- Economic for large area heating
Liquid Propane is the most usable heating fuel nowadays. It is suitable for the best brand heaters and works well both indoor and outdoor.
We recommend considering proper ventilation to avoid any risk of flame. Since the fuel creates carbon emission but the amount it emits surely lower than kerosene.
Here are some positive sides:
- It’s a clean fuel
- Easy to carry anywhere
- Variety of tank size offers you great joy over decision making & usage requirements
- Safe fuel
Natural gas is very similar to liquid propane and the advantages are widely the same. It’s a clean fuel and does not produce a bad odour. Here’s a little brief:
- Clean Fuel
- Enormous storage, so no chance of disruption
- You do not need a tank for this
Most of the large torpedo heaters support diesel as the fuel helps to generate a lot of heat. Diesel is suitable for heating a comparably large area. It’s ideal for commercial use. Being the top heat producer, a diesel burnt torpedo heater will cost you much.
Here’s why you will love to pay for that:
- Heavy amount of heat
- Suitable for both mounted and portable heaters
- You can use it in a suitable manner
- Suitable for construction sites and other commercial areas
Electric heaters are usually portable and small. It is good for indoor usage but there are a lot of heating choices that supports electricity.
You need to make a BIG ATTENTION over the voltage it requires before buying one.
Be careful, inappropriate volt may introduce another Hassel.
Advantages are as below:
- Does not burn any liquid fuel, so no flame
- Perfect for in-house use
- No odour
- Variety of sizes available
What other features do you need to consider before buying an air forced torpedo heater?
As you already know that the first important thing would be to figure out BTU as per the dimension of the heating place. However, there are more things you should be aware of before buying a torpedo heater.
Based on the requirement you need to choose the perfect size. If the heating place is comparably small and it’s indoor, you can go for the small-sized torpedo heater. However, if your requirement may vary you can buy a big one as a precaution.
Depending on the usage you may need to move the torpedo heater somewhere else. Since those are heavy, check for wheels before buying.
Most of the popular brands come with standard protection that shuts the torpedo heater off if anything goes wrong. You should never expect any flames coming around from your favourite heater I guess. It’s better to check once protection feature before making the final decision.
Venting / Ducting Facility
Many air-forced heaters have ducting available to send warm air inside while keeping the heater outside. If you’re worried about exhaust stepping into your space, ducting keeps the combustion at a secure distance without leaving you cold. Ducting requires a way to manoeuvre the air, in order that they are exclusive to forced-air type models.
You won’t expect the heater to warm up heavily that uses inefficient insulation inside. You need to keep in mind that torpedo warmers with heavy insulation require a premium price and for that, your budget needs to be flexible enough. (Source)
Know about the perfect propane tank
While using a propane run torpedo heater, you need to have a propane tank for that. To some people, it is difficult to identify the perfect propane tank. You have already known that heating capacity changes in line with the BTU that is discussed earlier.
However, as per the BTU, the size of your propane tank will differentiate accordingly.
|Propane Tank Size|
Up to 85000
Up to 125000
|Up to 175000|
