 Cold weather

There is typically a 0.5 degree F and 1 degree F increase in temperature for every foot of height. This means it can be as much as 10-20 degrees F hotter at the ceiling of a 20 ft high facility than at the floor. Moving the superheated air at the ceiling – where it obviously doesn’t do anybody any good – to floor level with a Bucket Fan is one of the least expensive and easiest ways to drastically cut utility bills by 1/4 to 1/3.

 Hot weather

In air conditioned buildings cold air coming out of ceiling duct work is fighting rising warmer air. The solution has always been to install tons of a/c as a way for the cold air to out-muscle the rising hot air. It’s been estimated that up to 40% of the input energy is wasted pumping out massive amounts of cold air in the attempt to overpower the warm air at the floor. Installing Bucket Fans near the cold air registers will actively push the conditioned air to where it should be, resulting in tremendous energy savings.

HOW TO CALCULATE THE NUMBER OF BUCKET FANS WHISPER YOU NEED
To enjoy the full benefit of destratification the accepted rule of

thumb is to «turn the air» between one and two times an hour.

To determine how many Bucket Fans are needed use this formula:

  • For ceiling heights 20 ft - 30 ft use the Bucket Fan Whisper 420
  • For ceiling heights 25 ft - 35 ft use the Bucket Fan Whisper 1055
  • For ceiling heights 30 ft - 45 ft use the Bucket Fan Whisper 1460


For example, a building has the following dimensions – 125 ft long, 75 ft wide, and 20 ft high.

  1. 125 x 75 x 20 = 187,500 cu. ft
  2. 187,500/1055/60 = 2.96 fans

1. H x W x L = V

    (Height x Width x Length = Air Volume in Building)

2. V/CFM/60 = Number of Fans

    V/CFM of the Bucket Fan/60

    (converts CFM to CFH) = Number of Fans


Always round up to the next number. In this example 3 Bucket Fans would be needed.
