1. What is a Panel Heater Size Calculator?

Definition: This calculator estimates the wattage needed for a panel heater based on room size and heating requirements.

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

2. How Does the Calculator Work?

The calculator uses the formula:

\[ W = SF \times WPSF \]

Where:

Explanation: The room area is multiplied by the heating requirement per square foot to determine total wattage needed.

3. Importance of Proper Heater Sizing

Details: Correct heater sizing ensures energy efficiency, proper heating, and prevents overloading electrical circuits.

4. Using the Calculator

Tips: Enter the room square footage and watts per square foot (default 10 W/sq ft). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical WPSF value?
A: Most rooms need 10 W/sq ft, but use 15 W/sq ft for poorly insulated spaces or colder climates.

Q2: How do I measure square footage?
A: Multiply room length by width. For irregular rooms, divide into rectangles and sum the areas.

Q3: Should I round up the wattage?
A: Yes, choose the next available panel heater size above your calculated wattage.

Q4: Does ceiling height matter?
A: Standard calculations assume 8-9 ft ceilings. For higher ceilings, increase WPSF by 10-20%.

Q5: Can I use this for multiple rooms?
A: Calculate each room separately as heating needs may vary by room type and insulation.
