Heating systems are one of the many ubiquitous conveniences of modern life. For many of us, central heating systems have always been a part of our lives. We only seem to notice heating systems when they are malfunctioning. Yet it took inventors and scientists to discover and understand heat transfer to then apply these principals for us to depend upon reliable heating systems. It behooves design engineers, operators and maintenance personnel to have a basic understanding of a few heat transfer concepts to ensure proper operation of heating systems. This course will discuss three types of heat transfer: convection, conduction and radiation. It will show how heating systems operate utilizing these forms of heat transfer acting in concert with each other. The operation of hot water and steam boilers along with electric heater will be examined. Finally, a brief explanation of controls for heating system will be presented.
