1. What is an Electric Garage Heater Size Calculator?

Definition: This calculator estimates the required heating capacity (in BTUs) for an electric garage heater based on the desired temperature increase and garage volume.

Purpose: It helps homeowners and professionals properly size electric heaters for garages to ensure efficient heating without overspending on oversized units.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ BTUs = \Delta T \times V \times 0.133 \]

Where:

Explanation: The formula accounts for the energy needed to raise the temperature of the air in your garage by the desired amount.

3. Importance of Proper Heater Sizing

Details: Correct sizing ensures energy efficiency, prevents short cycling, maintains comfortable temperatures, and extends heater lifespan.

4. Using the Calculator

Tips:

5. Frequently Asked Questions (FAQ)

Q1: What's a typical temperature increase for garages?
A: Most people heat garages 20-30°F above outdoor temperatures for comfort.

Q2: How do I convert BTUs to watts?
A: Divide BTUs by 3.412 to get watts (for electric heaters).

Q3: Does this account for insulation?
A: No, this is a basic calculation. Well-insulated garages need less heating power.

Q4: What if my garage has high ceilings?
A: Use the actual cubic footage (length × width × height) for accurate results.

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