How HVLS Fans Lead to Winter Savings - Hunter Industrial


For large buildings, it is difficult to maintain a comfortable environment throughout the colder months. This is especially true for warehouses or factories that must regularly open dock doors, exposing their workplace to frigid temperatures. This uncomfortable environment is detrimental to employees and leads to unsafe conditions and employee turnover. Many businesses attempt to solve this issue using their HVAC system to heat the building. For small buildings this method can be effective, but for large, open environments, HVAC systems are just not enough. For these businesses, installing high quality industrial ceiling fans is an effective way to spread heat around a large building, making a more comfortable environment and generating cost savings in the process.

Industrial fans, also known as high-volume, low-speed fans or industrial fans, achieve this through the process ofDESTRATIFICATION.


The principles of thermodynamics tell us that in an indoor environment, where gravity is the dominant force at work, hot air tends to rise to the ceiling. This means that all that hot air your HVAC system is pumping out is simply traveling to the ceiling, and not effectively warming your working environment. This leads to an uneven layering of temperatures in your facility, where the hot air is trapped at the ceiling and your ground level workspace is left uncomfortably chilly.

This layering of temperatures is known as STRATIFICATION, or the arrangement or classification of something into different strata (strata means layers). When it comes to achieving a comfortable working environment, having all the heat trapped at the ceiling is ineffective and, worst of all, expensive. In the cold winter months, using an HVAC system alone to heat a building is almost literally throwing money away: the hot air you are paying for is ineffective.

Attempting to heat a building using HVAC alone

Attempting to heat a building using HVAC alone keeps the hot air trapped at the ceiling and your workers left in the cold.

To fix this issue, the air in your facility must be DESTRATIFIED. In other words, the layers of air must be mixed to get the most out of the heat your HVAC system is providing. Industrial HVLS fans will help you attain this goal!


It is easy to think of a ceiling fan as something that is primarily used on hot summer days. While it is very true that ceiling fans in general, and HVLS fans in particular, generate a cooling effect when it is hot out, they are just as important in circulating heat in large buildings in the winter.

Have you ever heard that you should reverse your fan’s spin direction in the fall? That is because when a fan is spinning in reverse (counterclockwise for HVLS fans, clockwise for residential fans), air is pulled up through the fan blades, and pushed back down along the walls of a building. When it is cold out and the heater is running, HVLS fans effectively grab the hot air that is rising from the HVAC unit and spread it throughout a building. In this way, HVLS fans DESTRATIFY, or mix, the air in an environment, creating a more uniform, comfortable space.

HVLS fans recirculate the heat produced by your HVAC system, making your workspace more comfortable for employees and guest!

According to the American Society of Heating, Refrigerating and Air-Conditioning Engineers, “High volume, low speed (HVLS) fans are a prominent and practical means for reducing the floor-to-ceiling temperature gradient in large spaces.”

Not only do HVLS fans lead to a more comfortable environment, but also by circulating the heat your HVAC system is generating, you get more bang for your buck! In fact, HVLS fans are capable of saving you up to 30% on your energy costs!


Installing HVLS fans is a simple and effective way to keep your facility safe, comfortable, and productive, all while generating year-round savings. Are you ready to take the next steps?
