Which of the following types of heaters can be categorized as snow melting resistance heaters?

1. Baseboard heaters

2. Gas heaters

3. Radiant heaters

4. Heating cables

The correct answer is: Heating cables

Heating cables are specifically designed for applications such as snow melting, making them ideal for this category of resistance heaters. These cables can be installed under driveways, walkways, and other surfaces to provide heat and prevent the accumulation of snow and ice during winter months. By generating heat through electrical resistance, they effectively raise the temperature of the surface above freezing, allowing for safer conditions without the need for snow removal. In contrast, baseboard heaters function primarily in indoor heating applications to warm up rooms, gas heaters are generally used for heating air or spaces rather than surfaces, and radiant heaters are typically focused on providing heat to people or objects in a room rather than melting snow or ice on outdoor surfaces. Therefore, heating cables are uniquely suited to address the specific needs of snow melting in outdoor environments.
