1. What is an Infrared Heater Wattage Calculator?

Definition: This calculator estimates the wattage needed for an infrared heater based on the area to be heated.

Purpose: It helps homeowners and professionals determine the appropriate infrared heater size for a given space.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( W \) — Required wattage (watts)
• \( A \) — Area to be heated (square feet)

Explanation: The area is multiplied by 7 watts per square foot, which is the standard recommendation for infrared heating.

3. Importance of Proper Wattage Calculation

Details: Correct wattage ensures efficient heating, prevents energy waste, and maintains comfortable temperatures.

4. Using the Calculator

Tips: Enter the area in square feet that needs heating. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why 7 watts per square foot?
A: This is the general rule of thumb for infrared heating in moderately insulated spaces.

Q2: When would I need more than 7 watts/sq ft?
A: In poorly insulated areas, drafty spaces, or very cold climates, you might need 8-10 watts/sq ft.

Q3: Can I use this for other heater types?
A: This calculation is specific to infrared heaters. Other heater types may have different requirements.

Q4: What about ceiling height?
A: This calculation assumes standard 8-foot ceilings. For higher ceilings, increase wattage by 10% per additional foot.

Q5: Does this include safety margin?
A: No, consider adding 10-15% to the calculated wattage for optimal performance.
