1. What is an Electric Garage Heater Size Calculator?

Definition: This calculator converts electrical power input (in Watts) to heating power output (in BTU/h) for garage heaters.

Purpose: It helps determine the appropriate size of electric heater needed for garage spaces based on electrical specifications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Heating power (BTU/h)
• \( P \) — Electrical power input (Watts)

Explanation: The formula converts electrical Watts to British Thermal Units per hour (BTU/h), the standard measurement for heating capacity.

3. Importance of Proper Heater Sizing

Details: Correct heater sizing ensures efficient operation, proper temperature control, and avoids overloading electrical circuits.

4. Using the Calculator

Tips: Enter the electrical power rating in Watts. The calculator will show the equivalent heating capacity in BTU/h.

5. Frequently Asked Questions (FAQ)

Q1: What's the 3412 conversion factor?
A: This is the number of BTUs produced per hour by one Watt of electrical energy (1 Watt = 3.412 BTU/h).

Q2: How many BTUs do I need for my garage?
A: A general rule is 10-15 BTU per square foot, but this varies by insulation, climate, and desired temperature.

Q3: Can I use this for other electric heaters?
A: Yes, this conversion applies to all electric resistance heating systems.

Q4: What's a typical garage heater size?
A: Most residential garage heaters range from 5,000 to 30,000 BTU/h (1,500 to 8,800 Watts).

Q5: Does this account for heat loss?
A: No, this is a direct conversion. Actual heating needs may be higher due to insulation factors.
