A solar heating system that utilizes an electic fan to move warm air throughout a home is called a ___ system?

We Answered:

There are two general types of systems, active and passive. An active system uses energy to move heat energy around. A passive system uses convection to move the heat (heat can also radiate from warm surfaces to heat people and objects too).

In your question, a fan is used to move heat so it is an active system.

In a room that has sunlight coming into the room through windows warming say the floor, that would be an example of a passive system.

You are building a new home and are considering whether to install a solar heating?

Your money would be better spent on a geothermal system.
