Activent Cost Saving Information

Before you view the data...

Before you view the data please consider the following: Our test house was first measured to determine the 4 warmest rooms.

Then in these four rooms, we replaced the vents with Activents. When the room temperature was established the Activents closed, thus redirecting the warm air to other portions of the house. The house heated faster and the furnace turned off sooner. This resulted in energy savings and added comfort.
