1. What is a BTU per Sq Ft Garage Calculator?

Definition: This calculator estimates the heating load in BTUs per hour needed for a garage based on its area and the required BTU per square foot.

Purpose: It helps homeowners and HVAC professionals determine the appropriate heating capacity for garage spaces.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Q = A \times \text{BTU/ft}^2 \]

Where:

\( Q \) — Heating load (BTU/h)
\( A \) — Garage area (square feet)
\( \text{BTU/ft}^2 \) — BTU requirement per square foot (BTU/h·ft²)

Explanation: The garage area is multiplied by the BTU requirement per square foot to determine the total heating capacity needed.

3. Importance of Proper Heating Load Calculation

Details: Accurate heating load estimation ensures efficient heating, proper equipment sizing, and energy savings.

4. Using the Calculator

Tips: Enter the garage area in square feet and BTU per square foot requirement (default 30 BTU/h·ft² for typical garages). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical BTU/ft² value for garages?
A: Most garages require 30-50 BTU/h per square foot, depending on insulation and climate.

Q2: How does insulation affect the calculation?
A: Poorly insulated garages may need higher BTU/ft² values (40-50), while well-insulated ones may need less (20-30).

Q3: Should I include the ceiling height in this calculation?
A: Standard 8-9 ft ceilings are accounted for in the BTU/ft² value. For higher ceilings, increase the BTU/ft² value.

Q4: Is this calculation different for attached vs detached garages?
A: Yes, detached garages typically need more heating (higher BTU/ft²) than attached ones.

Q5: Does this include any safety factor?
A: No, consider adding 10-20% to the calculated value for optimal performance.
