Introduction to Living Space Equipment:
Focus on components located in living spaces that signal when heat is needed.
These components transfer heat into different rooms or zones.
Heat Transfer Methods:
Convection: Heat transfer through the movement of heated air or liquid (e.g., feeling warm air rising from a hot cup of coffee).
Conduction: Heat transfer through solid materials (e.g., feeling heat by touching a hot cup).
Radiation: Heat transfer through heat waves absorbed by a colder substance (e.g., feeling heat without touching a hot object).
Types of Heat Emitters:
Radiators: Transfer most heat through radiation and some through convection.
Made of cast iron or steel; steel radiators use more convection.
Convectors: Transfer most heat through convection.
Wall Convectors: Have aluminum fins attached to metal pipes, where hot water flows, drawing in cool air and heating it.
Fin Tube Baseboards: Air passes over heated aluminum fins to warm the space.
Fan Coil Units: Use forced convection to blow air over a hot water coil, often as backup heat.
Radiant Panels: Transfer over 90% of heat through radiation.
Can be installed in walls, ceilings, or floors, with hot water flowing through copper, steel, or PEX tubing.
Hydronic Radiant Floors:
Tubing laid beneath the finished floor carries hot water to heat the floor and the living space above.
