Heated Area Calculation:
From: | To: |
Heated area refers to the total square footage of a house that is heated by the primary heating system. This includes all living spaces but excludes unheated areas like garages, unfinished basements, or attics.
The calculation is simple:
Key points:
Details: Accurate heated area measurement is crucial for proper HVAC system sizing, energy efficiency calculations, real estate valuation, and building code compliance.
Tips:
Q1: What counts as heated area?
A: Any space with heating vents or radiators that is maintained at living temperatures during cold weather.
Q2: Should I include a sunroom?
A: Only if it has permanent heating and is used year-round. Seasonal sunrooms typically aren't included.
Q3: How does this differ from livable area?
A: Livable area might include some unheated spaces, while heated area specifically tracks spaces with heat sources.
Q4: Why is this important for HVAC?
A: Heating systems are sized based on the cubic footage of heated space to ensure proper capacity and efficiency.
Q5: How accurate should measurements be?
A: For most purposes, measurements to the nearest square foot are sufficient, though more precision may be needed for system design.
