Distribution systems are categorized according the medium used to transport heat. The two most common types are:
- Forced Air systems that use ducts and registers to distribute heated or cooled air, and
- Hot Water and Steam systems that use pipes and radiators to distribute heat.
Some systems need no distribution. These include space heaters, room air conditioners and room heat pumps that are located where heating or cooling is needed.
