Best Torpedo Heater 2021 Reviews

1. Mr. Heater MH60QFAV Portable Propane Forced Air Heater

Quiet and efficient so you can keep working and not be disturbed by the sounds of the heater in use. It is 50% quieter than any other propane heating device.

It is also extremely efficient and will operate for as long as 14 hours on a 20-pound propane cylinder.

That means this device is using very little fuel to create a wonderful source of heat. This unit is powerful enough to heat an area that has 1,500 square feet using the 30,000 to 60,000 BTUs of heat it produces.

It uses forced air to project the heated air out of the cylinder and throughout the room so you do not have a warm spot close to the heater and everything farther away from the heater is cold. It has a continuous electric ignition that allows you to light the heater without using an external flame source. 

It also protects you from the possible fires that happen with the delayed ignition devices. It has other standard safety features like automatic shut-off in the event of a tip-over or an overheating situation. It does use propane so it does produce carbon monoxide while in use and must be operated in a well-ventilated area.

2. Pro-Temp Propane Torpedo Heater

125,000 BTU will provide enough heat for an area of 3,100 square feet. You can also run this device continuously for about 24 hours on the propane from one 100-pound propane cylinder.

That means the device is effective, cost very little to operate, efficient, and powerful. It is everything you want in a heater and more.

With the variable heat settings, you get to choose how hot to keep a room and how much fuel the device uses.

If you set the unit on high long enough to take the chill out of the air and then reduce the heat setting to medium or low you can maintain the warmth in the room without using vast amounts of fuel.

It has continuous electric ignition so you do not need a match to light it. Simply depress the ignition button and select the speed you desire and let the unit start to heat. It is quiet enough that you can do the work you need to do and concentrate on something other than the sound of the heater roaring in the corner.

3. Dyna-Glo Forced Air Heater

You can go for the Dyna-Glo Forced Air Heater if your choice is not only a capable heater but also a stylish one. This heater has a BTU of 135,000, which is almost close to the Master MH-125-OFR Kerosene Fired Radiant Heater. However, there are versions with 50,000, 80,000, and even 180,000 BTU with different prices.

It has a wheelbarrow-type design with a large and durable wheel. Using kerosene, it offers a forced-air heating system. 

Also, the machine weighs only 52.25 lbs. You can heat up 3,200 sq. ft. with this heater. As it has a comfort control thermostat, you can set the temp beforehand, and it will get you that desired heat.

It uses a dual power source and has a long-lasting air pressure gauge. You can set the timer where it will run either till its tank is half or completely empty.

4. Mr. Heater Forced Air Propane Torpedo Heater

Quiet is the first thing you will notice about this torpedo heater. You will not be disturbed by the operational noise and can use it even inside where you are trying to sleep or watch television.

This device is as much as 50% quieter than the common propane heater.

This heater uses liquid propane to fuel the heating elements. You can connect it to the standard 20-pound propane cylinder.

It also requires an electrical outlet connected to a 115V power source to supply the forced fan with power. It is easy to set up, easy to maintain, and powerful enough to heat a very large area with the 75,000 - 125,000 BTUs it produces.

It is perfect for your patio or deck, backyard, workshops, garages and anywhere you need some heat.  There is a safety gas valve that has to be depressed while you are lighting this unit to prevent accidental gas release, or prevent children from being able to ignite the device.

It is a propane powered device so it does require you to provide ample ventilation to prevent carbon monoxide build-up and dangers. It is propane powered and you might smell the odor of propane slightly, but you should not get an overpowering odor of propane.

5. DeWalt DXH135HD Forced Air Torpedo Heater

Versatility combined with efficiency gives you this DeWalt force air kerosene burning heater. It is mounted on wheels so it is easy to move around and establish in any area you need it to be in. That makes it great around the farm when you might be working in the barn today and the outbuilding next to the corral tomorrow.

It can be fueled by kerosene, number one or two grade diesel and number one or two-grade heating oil. It has a continuous ignition that ignites and burns any excess fuel and eliminates fuel pooling and accidental explosions.

It has all of the latest safety technology designed into it. It has automatic shut-off in case of overheat situations or in case of an accidental tip-over. You do still need to make sure the unit is used in a well-ventilated area because burning these fuel sources will cause carbon dioxide which can be dangerous or deadly.

The device is a forced air heater so the heat is not simply close to the unit it is spread across the area by the blowing of the fan. Air is sucked in through the back of the device and blown out the front in a continuous stream of warmth.

6. Remington REM-140T-KFA-O Torpedo Heater with Thermostat

Reliable, rugged, and out-standing are just a few of the descriptive words that can be applied to this heating unit. You can also add versatile, easy to use, and magnificent. It is perfect for workshops, garages, farms, small businesses, construction sites, outdoor venues, and more.

Powerful is the only way to describe the ability to produce 140,000 BTUs that can effectively heat 3500 square feet of space. It is large but it has handles for you to hold onto when you are moving it.

It also has a base with wheels that allows it to be easily moved from one place to another without you having to lift the entire weight of the device and carry it.

It is thermostat controlled so you get to choose the temperature output that you like and then let the heater do the rest. It has forced air pushing the heated air out of the tube so it warms the people farther away from the device as effectively as it warms the individuals who are nearer to it.

This unit relies on kerosene for fuel. It is versatile enough to operate on number one and number two diesel fuel as well as number one and number two heating oil. 

7. ProCom PCFA40 Magnum Forced Air Torpedo Heater

Safety and style are designed into this propane fueled heater that can be operated off of multiple numbers of sizes of propane cylinders.

If you have a big shop and use 100-pound refillable propane bottles this heater can be connected to them and if you have a small shop that uses the simple 20-pound propane bottles this heater can be operated with that also. It remains cool to the touch so the worry of contact burns is removed. 

You can also keep the unit in closer proximity to things that otherwise might be ignited, burned, or damaged by sitting close to the heating device. It also has automatic shut-off features that protect you in the event that the unit is accidentally tipped over or overheats while in operation.

Push button ignitions allow you to start the heater up without using a match or external flame source. That allows you to light the unit safely with less risk of fire or danger. It does produce carbon monoxide so it is recommended that you ventilate the area it is used in.

8. Pro-Temp Kerosene/Diesel Forced Air Torpedo Heater

Diesel gives this device the power it needs to effectively heat an area up to 1,125 square feet. The heater produces as many as 45,000 BTUs and it is a forced air unit that evenly distributes that warmth throughout the room. It even has a built-in air pressure gauge and a simple function on and off switch.

This device is economical and will operate for as many as 14-hours on one five-gallon propane bottle of fuel. 

Propane is one of the cheapest gas fuels used by heaters, and this one uses a minute amount to provide you with the comfort you need and want. It does have a thermostat that keeps the device from heating the room too much.

You choose what temperature you like the room to be and let the heater maintain that selection. While it is in operation it can be noisy, but lower settings will help to reduce the amount of noise it creates.

It is designed with the safety cool to the touch features, and automatic shut-off features that protect you if the device gets knocked over or becomes overheated. Use only in an area that has proper ventilation.

9. Mr. Heater F270385 Contractor Forced-Air Torpedo Heater

Everything you could want from kerosene fueled heater, and then some more. It is designed on wheels so you can use the convenient handle on the end of the unit and tilt it like a wheel-barrow to maneuver it around from one place to another.

The wheels are oversized so they roll smoothly across the concrete, pavement, packed dirt, grass, or construction sites. This unit produces no flame while it is in operation so there is very little risk of fire. 

It also has automatic shut-off features that protect it and you if it were to be knocked over or if it were to over-heat during use. It even has cool to the touch technology designed into it so contact and surface burns are a thing of the past.

The adjustable thermostat on this device will regulate the temperature and keep you comfy. You do not have to worry about pipes freezing because the temperature was too low or about things getting overheated because the air in the room became too warm. You set the temperature and the unit maintains your choice.

10. Dyna-Glo RMC-FA60DGD Liquid Propane Torpedo Heater

A powerful heat source that produces up to 60,000 BTUs so it can be used in a large shop area to provide plenty of heat to keep you warm and comfortable. This unit has an adjustable heat angle so you can point the forced air in the direction you need for it to go. 

If you prefer the air to be forced upwards into the room you can tile the heater in that angle and if you prefer the heat to be forced in a downward trajectory you can force the heat in that angle.

The safety protection of this unit includes an automatic shut off if the sensors in the device determine that the unit is overheating or in danger of being damaged by too much heat.

The unit comes with a ten-foot section of heater hose and a regulator. It has an adjustable base that creates a solid foundation for the device. It also has a variable BTU dial that allows you to choose the temperature in the room. It is powered by propane and connects quickly to a 20-pound propane cylinder.

Torpedo Heater Buying Considerations

In order for you to buy the best Torpedo heater for your needs, you must have a little information that will help you to compare features. Knowing what features are offered on these devices will allow you to compare the items, and make an educated choice on which item to purchase.

I suggest making a written list of the appliances you find that you like. Then compare the pros and cons of each appliance and weigh the benefits they offer. This will give you more bang for your buck, because the device you get will have everything you like, want or need.


The main consideration when buying a torpedo heater is what size heater to buy. In order to accurately choose the proper size heating unit. you will need to first determine what you need the heater to do for you. 

Supplemental Heat

If you plan to use the torpedo heater to help heat a room that already has a primary heater such as a central heating unit then you can buy a smaller heater. 

Primary Source Heat

If you plan to use the device as the primary source of heat in a room then you will want to consider the size of the room you are heating. When you are using the device as a primary heat source you will need to consider how much insulation the room has in it, and how many square feet the room has. Then you choose the unit by the number of BTUs that it provides and the number needed for the room size you have.

If you have a room that measures 12 x 12 and have very little insulation in the walls and ceiling you will need about 9,000 BTUs to heat properly. If the same size room has good insulation then you will only need a heating unit that can produce 4,000 BTUs.

Safety Features

 These heating appliances may have several safety features included. The primary safety features you will find are:

  • Overheat protection that usually includes an automatic shut-off feature if the device overheats
  • Cool to the touch surface area
  • Anti-tip over which usually automatically shuts the unit off if it is tipped over

Heater Height

These devices can come in a variety of heights. If you have children or pets that will be around the unit then you may want to choose a device that is taller.

Noise Level

You want to get a device that is quiet. These units emit varying degrees of noise so choose the quietest one you can that is still in your price range.

What is a Torpedo Heater? 

A torpedo heater is a heating appliance that is powered by a variety of fuels. Common torpedo heater fuels are electricity, propane, natural gas, diesel, and kerosene. Propane heaters are often the most popular because the fuel is readily available and less costly than some of the other fuels.

These heating appliances are small and generally used to heat one room or as supplemental heat in a room. They are uniquely shaped so that the heat is forced from one end of the unit instead of from a front panel. They are effective, user friendly, and offer many benefits such as cool to the touch surfaces.

Types of Torpedo Heaters

There are different types or styles of torpedo heaters. There are also different fuel varieties used by these heating devices. The following is a quick break-down of the heater types.

Forced Air Units

Forced air units use a fan to blow the warm air they create around the room. These units suck air in from the back section of the heater and then they expel that air out the front portion of the unit. As the air is processed from the rear of the tube into the front of the tube it passes heating elements that warm it up


The electric heaters use electricity instead of a combustible fuel source. They do not produce harmful gases like carbon monoxide. They do however use electricity and generally, they are more expensive to operate than the gas-powered versions.

The torpedo heaters that are electric have fans to blow the heated air out of the tube just like the gas versions have. The electric heaters are often quieter, and many people believe they are easier to use because you simply plug them in and do not have to have an added fuel source like a propane cylinder.


Propane is an efficient heating fuel that costs less than most other heating fuels. It is readily available in small containers such as the 20-gallon propane bottle so the heater remains easy to fuel and portable.

Propane does produce carbon monoxide and other harmful gases. You should always make sure the area it is burned in has proper ventilation and air circulation.

Natural Gas

Natural gas is a clean-burning energy source but it requires you to have a hard line connected to your heater because natural gas does not come available in small cylinders like propane.

Natural gas produces no odor, but it can produce carbon monoxide and other harmful gases so you will need great ventilation in the room.


Diesel is a popular fuel for some models of torpedo heater. Diesel fuel is easy to obtain, and it is fairly reasonable in price. Diesel can produce an unpleasant odor that many people find offensive.

Diesel produces carbon monoxide so the ventilation must be good.


Kerosene is a common heating fuel, but in some areas of the country, kerosene is not readily available. Make sure that you have a kerosene supply close to your home before you choose this type of fuel.

Kerosene produces harmful gases when burned so proper ventilation is required if you use this fuel source.

Frequently Asked Questions

1. Are torpedo heaters safe to use indoors?

These heaters are designed to be used indoors and are often the top heater choice in workshops and garages. You simply have to make sure that the area the heater is established in has adequate ventilation to prevent carbon monoxide build-up or another toxic gas build-up.

2. Can I use a torpedo heater to kill bed bugs?

The torpedo heater will not increase the temperature to a degree that will effectively exterminate bed bugs. Heat treatment to kill bed bugs requires a very high heat concentration and should not be attempted by anyone other than a professional bedbug exterminator.

3. Do you need ventilation when using a propane torpedo heater?

If the heater you are using burns any type of gas or propane then you need ventilation to prevent carbon monoxide poisoning. This harmful gas is produced when fuels like gas, propane, natural gas, diesel, and kerosene are burned. If the heater you have is electric then it will not produce carbon monoxide gas and will not require ventilation.

Final Note

If you would like a torpedo heater that has a variable BTU dial so you can choose the precise amount of heat that is produced, we suggest the Dyna-Glo RMC-FA60DGD.

If you are looking for a powerful torpedo heater that can be operated on kerosene, or diesel fuel, or heating oil, and can heat an area with as many as 3500 square feet then we recommend the Remington REM-140T-KFA-O.

The torpedo heater that you choose should be large enough to heat the square footage that you need warming, but should not be too large. A unit that is too large may overheat trying to warm a space that is too small. Always provide proper ventilation when using gas-burning appliances.
