Study Notes
- Air distribution in homes can be done through forced-air, gravity, or radiant systems.
- Forced-air systems use a blower to distribute warm or cool air through ducts.
- Gravity systems rely on the natural rising of warm air and cannot distribute cool air.
- Radiant systems warm walls, floors, or ceilings, or use radiators to warm the air.
- Radiant systems cannot distribute cool air.
- Hydronic systems use a pump to circulate heated water to radiators or convectors.
- Modern radiant systems use hot water pipes under concrete slabs to warm the air.
- Forced-air systems may have blower malfunctions and add electrical power costs.
- Gravity systems may have heat registers positioned high on walls.
- Radiant systems may have clogged pipes or malfunctioning boilers.
