Forced Air Heating System Sarah Catherine Nick Henry

Steps to A Heating System 3 steps  Burn a Fuel  Heat a fluid  Circulate a heated fluid The second law of thermodynamics states the energy flows from hot to cold. In a forced air heating system this happens through convection.

Role of energy flow After the first 3 steps of a heating system air is pushed through supply ducts. It goes through a heat registered and warm air rises. The air circulates the room and the cold air falls through a return grill. Air is pulled through the return ducts and the process starts again.

Insulation Definition: a material that is a poor conductor of heat and that delays the transfer of heat Good insulators are:  Air  Styrofoam  Wall Insulation
