3. Introduction – Managing Air in Winter
Winter indoor air balance is challenging in
large spaces.
Uneven heating causes cold floors and hot
ceilings.
HVLS fans circulate air efficiently.
Improves comfort and lowers energy costs.
Optimizes winter energy performance.

4. Large buildings lose heat quickly.
Warm air rises, causing stratification.
Cold floors create worker discomfort.
Heating systems work harder to maintain
warmth.
Leads to high energy bills and inefficiency.

5. Understanding Temperature Stratification
Warm air rises, creating temperature
gradients.
Temperature rises 0.5–1°C per foot.
Heaters overwork, wasting energy.
Destratification pushes warm air down.
HVLS fans efficiently equalize temperatures.

6. HVLS fans move large volumes of air slowly.
Gentle airflow mixes warm and cool layers.
Minimizes heat loss and cold drafts.
Supports heating systems for stable
temperatures.
Reduces reliance on HVAC for comfort.

7. Energy Savings & Performance Benefits
Up to 30% reduction in heating energy costs.
Even temperature distribution enhances
occupant comfort.
Lower heater runtime extends equipment
lifespan.
Reduced CO₂ emissions and improved
sustainability.
Payback within 1–2 winters through energy
savings.

8. Warehouses and distribution
centers maintain warmth.
Automotive and manufacturing
reduce fuel use.
Gyms, commercial spaces, and
barns improve comfort.
Cold storage and logistics use
HVLS for air balance.
Heating costs show measurable
reduction.

9. Maintenance & Winter Operation Tips
Run fans in reverse for winter
destratification.
Keep blades clean for efficiency.
Inspect motors and controls regularly.
Adjust speed based on the building and
heater.
Use smart controls for energy optimization.
