Floor Warming, Primary Heating, Snow Melting & Roof De-Icing with PTC Heaters
With a radiant heat system, the temperature profile associated with a forced-air system is switched around, and the entire floor becomes the radiator. The heat radiates from the floor, warming all of the objects in the room, and everything in the room gains a warm, comfortable feel to it. This course evaluates self-regulating polymer technology and the performance benefits of using PTC (positive temperature coefficient) heaters for energy efficient floor warming, primary heating, snow melting, and roof de-icing.
Upon completion of this course, the Learner should be able to:
- Discuss the underlying principles of heat transfer and the advantages of radiant heat.
- Compare the operation and installation of radiant heating systems.
- Explain how self-regulating polymer technology works and identify specific applications across a variety of construction sectors.
- Discuss the energy efficiency and performance of PTC (positive temperature coefficient) heaters.
- Discuss the advantages of using PTC heaters for floor warming, primary heating, snow melting and roof de-icing.
