1. What is an Electric Heating Room Size Calculator?

Definition: This calculator estimates the electric heating requirement in watts based on room area in square feet.

Purpose: It helps homeowners and professionals determine the appropriate electric heating capacity needed for a room.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( W \) — Heating requirement (Watts)
• \( A \) — Room area (square feet)

Explanation: The room area is multiplied by 10 watts per square foot, which is a standard rule of thumb for electric heating in well-insulated spaces.

3. Importance of Proper Heating Calculation

Details: Accurate heating requirement estimation ensures comfortable temperatures, energy efficiency, and proper sizing of heating equipment.

4. Using the Calculator

Tips: Enter the room area in square feet. The value must be > 0. The result shows the recommended heating capacity in watts.

5. Frequently Asked Questions (FAQ)

Q1: Why 10 watts per square foot?
A: This is a general guideline for well-insulated spaces. Poor insulation may require 12-15 watts/sq ft.

Q2: Does this apply to all room types?
A: Bathrooms may need more (15-20 watts/sq ft), while bedrooms may need less (8-10 watts/sq ft).

Q3: What about ceiling height?
A: For ceilings higher than 8 feet, increase the wattage proportionally (e.g., 10% more for 9 ft ceilings).

Q4: Is this for continuous or supplemental heat?
A: This calculation is for primary heating. Supplemental heat may require less wattage.

Q5: How do I convert to BTU/h?
A: Multiply watts by 3.412 to get BTU/h (British Thermal Units per hour).
