1. What is an Electric Heater Room Calculator?

Definition: This calculator estimates the power requirement (in watts) for an electric heater based on room area.

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( W \) — Heater power requirement (watts)
• \( A \) — Room area (square meters)

Explanation: The formula provides an approximate calculation of 100 watts per square meter, which is a common rule of thumb for standard room heating.

3. Importance of Proper Heater Sizing

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

4. Using the Calculator

Tips: Simply enter the room area in square meters. The result shows the approximate heater power needed in watts.

5. Frequently Asked Questions (FAQ)

Q1: Is 100W per m² always accurate?
A: This is a general estimate. Actual needs may vary based on insulation, ceiling height, and climate.

Q2: What if my room has high ceilings?
A: For ceilings over 2.7m, consider increasing the power by 10-20% per additional meter of height.

Q3: Does this work for all room types?
A: Bathrooms may need more power (120-150W/m²), while well-insulated rooms might need less (80W/m²).

Q4: How does this translate to BTU?
A: Multiply watts by 3.412 to get BTU/h. For example, 1000W ≈ 3412 BTU/h.

Q5: Should I round up the result?
A: Yes, it's recommended to choose the next available heater size above your calculation.
