Choosing the right duct heater requires the careful consideration of many factors. You must consider the medium to be heated, wattage required, duct size, the installation requirements, and the desired electrical controls.
Some duct heaters are designed for high-temperature use. They provide clean heat, offer versatility, require little maintenance, and are considered easy to install. High temperature duct heaters are also used in annealing and dehumidification as well.
