A Salamander heater is any of a variety of portable forced-air or convection heaters used in ventilated areas for worksite comfort. Salamander heaters are most often found at construction sites. Depending on style, they can also be referred to as "torpedo furnaces", "Salamander furnaces", or simply, "Salamanders". The origin of their name is unknown, although a traditional wood-burning stove in (Chilean) Spanish and Portuguese is known as a "Salamandra".
