1. What is an Electric Radiator Size Calculator?

Definition: This calculator estimates the wattage required for an electric radiator based on room volume.

Purpose: It helps homeowners and professionals determine the appropriate size of electric radiator needed to effectively heat a room.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( W \) — Radiator wattage (Watts)
• \( V \) — Room volume (cubic meters)

Explanation: The standard calculation uses 40 watts per cubic meter as a general rule for moderate climates.

3. Importance of Proper Radiator Sizing

Details: Correct sizing ensures efficient heating, prevents energy waste, and maintains comfortable room temperatures.

4. Using the Calculator

Tips: Measure your room's length, width, and height to calculate volume (L × W × H in meters). Enter the volume in cubic meters.

5. Frequently Asked Questions (FAQ)

Q1: Why 40 watts per cubic meter?
A: This is a standard value for moderate climates. Colder areas may need 50-60 W/m³, while warmer areas may use 30-35 W/m³.

Q2: What if my room has high ceilings?
A: For rooms with ceilings over 2.4m, consider increasing the wattage by 10-20% to account for the additional volume.

Q3: Does this account for insulation?
A: No. Poor insulation may require 10-25% more wattage, while excellent insulation may need 10-15% less.

Q4: What about room type?
A: Bathrooms typically need more heat (50-60 W/m³), while bedrooms may need less (35-40 W/m³).

Q5: How do I convert room dimensions to cubic meters?
A: Multiply length × width × height in meters. For example, 4m × 5m × 2.5m = 50 m³.
