1. What is a Garage Heater BTU Calculator?

Definition: This calculator estimates the required heating capacity (in BTU/h) for a garage based on its area, BTU per square foot, and adjustment factors.

Purpose: It helps homeowners and professionals determine the appropriate size of garage heater needed for effective heating.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Q = A \times BTU/ft² \times F_g \]

Where:

\( Q \) — Required heating capacity (BTU/h)
\( A \) — Garage area (square feet)
\( BTU/ft² \) — Heating requirement per square foot (BTU/h·ft²)
\( F_g \) — Garage-specific adjustment factor

Explanation: The garage area is multiplied by the base heating requirement and then adjusted for garage-specific conditions.

3. Importance of Proper BTU Calculation

Details: Correct BTU calculation ensures efficient heating, prevents energy waste, and helps select the right-sized heater for your garage.

4. Using the Calculator

Tips: Enter the garage area in square feet, BTU per square foot (default 20 BTU/h·ft²), and adjustment factor (default 1.0). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical BTU/ft² for garages?
A: Most garages require 20-30 BTU per square foot, depending on insulation and climate.

Q2: When should I adjust the factor (F_g)?
A: Increase for poor insulation (1.5), cold climates (1.2-1.5), or decrease for well-insulated spaces (0.8).

Q3: How do I measure my garage area?
A: Multiply length by width of your garage in feet to get square footage.

Q4: Does this include ceiling height considerations?
A: The default values assume standard 8-10 ft ceilings. For higher ceilings, increase the factor.

Q5: Should I round up the calculated BTU?
A: Yes, it's recommended to round up to the nearest heater size available.
