Understanding Furnace Sizing

Proper furnace sizing is crucial for efficient heating and comfort in your home.

  • BTU Requirements British Thermal Units (BTU) measure the heating capacity needed for your space.
  • Climate Considerations Local climate significantly affects the required furnace size.
  • Insulation Impact Better insulation reduces the required furnace size and improves efficiency.
  • Sizing Factors Square footage, ceiling height, and local climate all affect proper sizing.

Design Considerations

Heat Loss Calculation

Consider windows, doors, and insulation quality when calculating heat loss.

Energy Efficiency

Higher AFUE ratings indicate better energy efficiency but may cost more initially.

Zoning Requirements

Multiple zones may require special consideration for proper heating distribution.

Safety Margins

Include a 10-15% safety factor in BTU calculations.
