1. What is a Panel Heater Size Calculator?

Definition: This calculator estimates the appropriate panel heater wattage needed based on room area.

Purpose: It helps homeowners and professionals determine the right size panel heater for efficient room heating.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( W \) — Heater wattage (Watts)
• \( A \) — Room area (square feet)

Explanation: The standard rule of thumb is 10 watts per square foot for adequate heating in well-insulated rooms.

3. Importance of Proper Heater Sizing

Details: Correct sizing ensures energy efficiency, proper heating, and prevents overworking the heater.

4. Using the Calculator

Tips: Enter the room area in square feet. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why 10 watts per square foot?
A: This is a standard estimate for moderately insulated spaces. Adjust up or down based on insulation quality.

Q2: When would I need more than 10 watts/sq ft?
A: In poorly insulated rooms, drafty spaces, or very cold climates, you might need 12-15 watts/sq ft.

Q3: Can I use multiple smaller heaters?
A: Yes, you can divide the total wattage among multiple heaters for better heat distribution.

Q4: Does ceiling height matter?
A: Standard calculations assume 8-foot ceilings. For higher ceilings, increase wattage by 10% per additional foot.

Q5: What about other heat sources?
A: If you have significant other heat sources (sunlight, appliances), you might reduce the wattage slightly.
