Room to Room Fan Clears the Air, Saves Energy

February 20th, 2009 by  


Ok, so this probably isn’t necessary here in weather-neutral San Francisco, but those of you living in areas prone to intense hot and cold spells might want to take a look at the Room to Room Fan, a compact $30 door fan that circulates air into adjoining rooms.

The fan is an ultra-cheap way to move air from your heater or air-conditioner around the house— and that means there’s less of a need to crank up the temperature controls. The door frame fan, which is available on the Improvements Catalog website, moves 120 cu. ft. of air per minute and circulates air in an average room (10’x12′) three times per hour.

    Back in the days before AC (yep, I was around back then) my aunt and uncle installed a fan in their ceiling that pulled hot air from the house and shoved it into the attic.

    During the day they left the basement door open which allowed cooler air to move up from below the house. The hottest air would have collected at the ceiling and that air, in turn, would have pushed the very hot air out of the attic.

    In the evening the basement door was closed and open windows allowed cooler evening air to cool the house.

    Now we tend to use massive amounts of energy to cool hot air. Seems like we could rethink our cooling strategies and cut our AC use. Moving air doesn’t take a lot of energy compared to moving heat.

    would this take hot air from a conservatory into a cooler room in the house/

    New Department of Energy regulations mandate that power companies and energy providers may not put any restrictions on the trade of energy i.e. selling your power back to the power company. Of course they can make you run a gauntlet as far as safety is concerned. The energy industry has a traded market just like the oil industry, and theoretically having a shed full of batteries could make you money if you downloaded at night and resold at peak hours.

  • Great idea. Sometimes all you need to make a difference is good circulation through the rooms.
