Torpedo Heaters

Torpedo heaters deliver a focused stream of forced-air heat to help take the bite out of cold workdays in suitable, well-ventilated work areas. Often called salamander heaters, these portable heaters pair a heat source with a fan that moves warm air toward the area where you’re working. Fuel-burning models may run on propane, kerosene or diesel, but each heater requires the fuel specifically approved by its manufacturer. Many also need an electrical connection to operate the fan and controls, so access to power matters along with your fuel supply. To narrow down your options, start with the heater’s British thermal unit, or BTU, rating and the manufacturer’s sizing recommendations. Square footage is only part of the picture: ceiling height, insulation, outdoor temperatures and frequently opened overhead doors all affect heating needs. Matching a torpedo heater to your workspace helps you plan for cold-weather equipment maintenance, shop projects and other chores without choosing by heat output alone. Choosing a portable forced-air heater also means thinking through placement, ventilation and everyday operation before bringing it into your workspace. Fuel-burning torpedo heaters can produce carbon monoxide and are not intended for living spaces or enclosed areas without the ventilation required by the manufacturer. An open door alone does not necessarily provide enough fresh air, and a carbon monoxide alarm does not replace proper ventilation. Keep the heater on a stable, level surface with the specified clearance from lumber, hay, bedding, fuel containers and other combustible materials. Direct airflow away from people and animals, and keep walkways clear of cords and fuel hoses. As you compare torpedo heaters, check operating details such as fuel consumption, tank capacity or propane connection requirements, thermostat compatibility and available heat settings. Those details can help you estimate run time and choose controls that fit your routine. Follow the owner’s manual for startup, shutdown and maintenance, shut the heater off and let it cool before refueling, and never leave it running unattended.
