What is a torpedo heater?

A torpedo heater, also known as a Salamander heater, Salamander, Salamander Furnace, or Torpedo furnace is a forced-air or convection heater that generates heat from the combustion of fuel and then uses a fan to push the heated air out of the unit.1

The beauty with these fans is that they are portable.

There are a number of ways they are fueled including propane, kerosene, diesel, natural gas, multi-fuel or electric.

The torpedo heater is generally used in areas with good ventilation, often at construction sites, warehouses, workshops, and sporting events amongst others.

Though they have been around since the 1915’s they became more popular in the 1950s when Scheu Manufacturing Company developed the modern Salamander heater to provide warmth on construction sites, enabling workers to work in the cooler weather. Lucky workers!

How does a Torpedo heater work?

A Torpedo heater works much the same way as a forced air heater for your home in that warm air is created and pushed out via a fan.

Inside the torpedo heater, there is a burner which, when the fan is turned on is ignited.

There are a few different types of fuel used to ignite the burner, which each have their pros and cons.

The fuel is gravity fed into the burner which creates the heat inside the unit.

From there the heat is pushed out via an electric fan into the area the fan is facing.2

The following video gives some good insight into how a torpedo heater works.

Kerosene Torpedo Heaters/ Kerosene Salamander Heaters

One of the most common types of torpedo heater is one that is fueled by Kerosene.

It is important to note that Kerosene comes in different grades and using the incorrect grade can void the warranty of some machines.3

So if you plan to purchase a kerosene heater, pay particular attention to that.

The benefits of using Kerosene as a fuel is that Kerosene releases more energy than propane and therefore creates more heat.

So, in essence, you are getting more bang for your buck with kerosene than propane.

It does, however, have a strong smell.

Along with that when burned it produces carbon monoxide so you have to be sure to use a kerosene heater where there is adequate ventilation (outside).

Obviously, it is not an environmentally friendly option.

Kerosene is a little bit more difficult to purchase than propane gas given propane is commonly used for gas and BBQ cookers, so is stored by many service, grocery, and convenience stores.

If you plan to stockpile your fuel Kerosene can be a good option.

With proper storage, Kerosene can keep for up to 2-5 years so it has a very good shelf life in the right storage conditions.4

Propane Torpedo Heaters / Propane Salamander Heaters

Another form of fueling for torpedo, or salamander heaters is propane.

Propane (also know as LP Gas or LPG) is a by-product of natural gas and is used most commonly for fueling gas bbq’s.

The good thing about propane is that it is much more environmentally friendly than kerosene producing minimal emissions.

Funnily enough, propane is odorless and colorless and a chemical compound is added to it to help people recognize any leaks which may become a hazard.

Obviously, propane is highly combustible and is not safe for inhalation.

As far as energy goes propone is a bit more expensive with kerosene costing approx $2.25 per gallon and propane $3.00 per gallon.5 (This figure will likely vary but you get the idea)

Propane also has less energy than kerosene with roughly 91,333 BTU’s of energy potential per gallon while Kerosene has roughly 135,000 BTU’s of energy potential per gallon.6

best diesel torpedo heater

Diesel Torpedo Heater

Depending on where you live, there is often a few very good reason why you might want to use Diesel over kerosene as a fuel source.

It’s cheaper and often more accessible.

There are dedicated diesel torpedo heaters available however these days new models of torpedo heaters actually have multi-fuel capability.

Many people ask whether you can use diesel in their kerosene heater and while this works on a technical level it is highly recommended you don’t for safety reasons.
Diesel burns a lot dirtier than Kerosene so there are a lot more fumes and odor. ALWAYS have proper ventilation.

Multi Fuel Salamander / Torpedo Heaters

As mentioned above there are many new salamander heaters now that are able to run on multiple fuel sources.

For example, this heater can run on Kerosene, 1 and 2 diesel fuel, 1 and 2 fuel oil and jp8/jet a fuel.

This certainly makes things more convenient in regards to the aforementioned prices and availability of fuel.

What to look for when purchasing a Torpedo Heater

Torpedo Heater Thermostat

Some salamander heaters have a thermostat equipped so you are able to regulate the temperature of the area you are heating. 

If you are using the heater outside it will obviously not be much use, but for interior location such as well vented warehouse a thermostat could be a feature worth considering.

Fuel Source

Above we ran through the different types of fuel sources which can be used with torpedo heaters.

The pros and cons of each with help you determine which kind of fuel is best for your situation.

Safety Features

Safety consideration is hugely important with torpedo heaters as there are a lot of variables that ripe for danger.

Manufacturers are required to meet certain levels of safety and below are some features manufacturers have built into their heaters.

• Agency approved safe for use on combustible flooring
• Tip-over shutoff and back pressure switch for safety
• CSA Certified for Safe Use Both Indoor and Outdoor
• UL Listed
• Overheat Auto-Shut-off Protection
•  High limit switch and thermoelectric safety valve
• Fuse protected electrical system

At minimum, you want to make sure the heater you are purchasing is CSA approved for the area you are using it (indoor or outdoor).

Fuel Gauge

A neat feature some heaters have is a runtime fuel gauge.

This will enable to see how much time you have before your fuel runs out.

This is great for planning ahead and ensuring you are always ready to refuel and avoid any cold stretches!

Adjustable Heat Angle

Some torpedo heaters have a built-in mechanism which will allow you to adjust the unit up and down which will give you slightly more control over where your heat is going.

Tank Size

Think about the size of the tank that you might want.

Will you need to lift/move it by yourself?

Do you need the biggest tank you can get?

These are a couple of questions you might want to ask yourself when you are looking at the various models.

Variable Heat Settings

This feature gives you more control over the temperate coming out of the heater.

This is useful if you are wanting more than just one ‘speed’.

What are BTU’s?

BTU stands for ‘British Thermal Unit’ and is a measurement of energy.

It is defined being the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.

Obviously, the higher the BTU’s of the heating unit, the more heat will be output.

Noise

Some torpedo heaters can be quite noisy.

This has been a common gripe and some brands have recognized this and market some of their units as being much quieter than regular units.

If the noise level is important to you, this is something to bear in mind.

torpedo heater safety

Torpedo Heater Safety

When purchasing a torpedo heater it is very important to understand the safety requirements – if neglected then there is a possibility of fatalities.
