Links to articles detailing each type of building cooling or heating system

This article provides a table summarizing the various typs of heating or cooling systems.

For each system type we include a link to our home page for information about that type of cooling or heating equipment.

Page top photo: an older type of warm air heating system, a "gravity furnace" that distributed heated air up into the building through a single floor grate, using natural convection to heat the building.

Gravity furnaces were fired at first by coal or sometimes wood, later by oil or gas fuel.
