1. What is Watts per Square Foot?

Watts per square foot (W/ft²) is a measurement of power density that calculates how much power (in watts) is distributed over a given area (in square feet). This is particularly important for tiled heating systems where typical values range between 10-15 W/ft².

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( W/ft² \) — Power density in watts per square foot
• \( P \) — Total power in watts (W)
• \( A \) — Area in square feet (ft²)

Explanation: The equation divides the total power by the area to determine how concentrated the power is across the surface.

3. Importance of Power Density Calculation

Details: Calculating watts per square foot is crucial for designing heating systems, ensuring proper heat distribution, and avoiding overheating or insufficient heating in tiled areas.

4. Using the Calculator

Tips: Enter the total power in watts and the area in square feet. Both values must be positive numbers. Typical tiled heating systems use 10-15 W/ft².

5. Frequently Asked Questions (FAQ)

Q1: What's the typical range for tiled heating systems?
A: Most tiled heating systems operate between 10-15 W/ft² for comfortable and efficient heating.

Q2: How do I convert to watts per square meter?
A: Multiply W/ft² by 10.764 to get W/m² (since 1 ft² ≈ 0.0929 m²).

Q3: What factors affect power density requirements?
A: Room insulation, desired temperature, floor covering, and heat loss all affect the required power density.

Q4: Is higher W/ft² always better?
A: No, excessive power density can damage flooring materials and create uncomfortable hot spots.

Q5: How does this relate to electric floor heating?
A: This calculation helps determine the appropriate heating mat or cable spacing for electric floor heating systems.
