Salamander heaters are high output heaters used to heat large open areas. They feature a high energy heat source and a fan that pushes cold air past the heat source. They were developed in the 1940s and are also known as salamander ovens or torpedo ovens. They can use gas, kerosene, or high output electrical elements as power sources. Safety considerations include the risk of fire and oxygen depletion in small spaces.
A salamander heater is a high output forced air or convection heater. Salamander heaters are most commonly used to heat the air in large open areas such as patios, building sites or workshops.
Salamander heaters feature a high energy heat source such as a gas or kerosene flame or high wattage electrical element, contained within an open ended tube. A fan located at one end of the tube pushes cold air past the heat source. This heats the air instantly, providing convection heating to the outdoor area.
Did you know that? Salamander heaters are also known as “salamander ovens”, “torpedo ovens” or “torpedo ovens”, depending on their design.
The development of the salamander heater
The modern salamander heater was developed in the early 1940s by the Scheu Manufacturing Company as a high performance space heater. The heater was designed to be highly effective in large areas that were traditionally difficult to heat, such as warehouses, factories and construction sites, whilst being simple and portable.
The salamander stove takes its name from the salamander, an amphibian which, according to medieval and Renaissance folklore, was said to live in fire.
The original 1940s salamander heater featured a kerosene burner, and many salamander heaters continue to use kerosene. Gas burners and high output electrical elements have also been incorporated into the salamander heaters, offering a variety of power sources to suit a wide range of different applications. In fact, some variants of the salamander heater are equipped with peripheral components which allow the use of fuels such as diesel. In the case of liquid fuel models, the fuel tank is usually mounted on the heater tube.
How does a salamander heater work?
First, the burner is ignited, providing a powerful internal heat source.
The fan is then turned on, which draws in the cold outside air and pushes it along the tube, past the heat source.
This instantly heats the air, which is then expelled out the other end of the tube, into the area to be heated.
To control the heater output, the heat source or fan speed can be adjusted manually. In some cases, the output is regulated by an automated thermostat system.

Safety considerations for using a salamander heater
As simple and effective as the salamander heater is, there are several safety considerations to keep in mind.
The most obvious safety issue is the risk of fire when the heater is used near combustible materials.
When gas burners are used, salamander heaters can pose an oxygen depletion risk in small spaces. For this reason, they should always be used in well-ventilated areas.
The high instantaneous power of the heaters can create a large amount of condensation in the heated area.
