Introduction to Inspecting Heating Systems has earned an average of 4.50 out of 5 stars from 72 ratings.
Heat energy can be transferred by conduction, convection, and radiation. Conduction is the transfer of heat from one molecule to another and only happens in solid materials. Convection is the transfer of heat via a moving fluid. Radiation occurs when certain energy waves strike an object, are absorbed, and turn to heat.
There are many types of heating systems, and they all are categorized based on the source of thermal energy they use to generate heat. Sources of thermal energy include natural gas, oil, electricity, solar energy, geothermal energy, and wood. This course will exam various sources of heat and identify ways to transfer heat energy. In addition, the course will specify characteristics of various heating systems including freestanding and area heating systems.
