Wattage Formula:
From: | To: |
Definition: This calculator estimates the wattage needed for an electric radiator based on room volume.
Purpose: It helps homeowners and professionals determine the appropriate radiator size for efficient room heating.
The calculator uses the formula:
Where:
Explanation: The standard calculation assumes 40 watts per cubic meter for adequate heating in typical conditions.
Details: Correct wattage ensures efficient heating, prevents energy waste, and maintains comfortable room temperatures.
Tips: Enter the room volume in cubic meters. The value must be > 0. The calculator assumes standard insulation conditions.
Q1: Why 40 watts per cubic meter?
A: This is a standard estimate for moderately insulated rooms in temperate climates.
Q2: When should I adjust this calculation?
A: Increase by 10-20% for poorly insulated rooms or very cold climates; decrease for well-insulated spaces.
Q3: How do I find my room volume?
A: Multiply room length × width × height in meters. For irregular rooms, divide into sections.
Q4: Does this work for all radiator types?
A: This calculation is specifically for electric radiators. Other heating systems may have different requirements.
Q5: What if my room has high ceilings?
A: For ceilings over 2.7m, consider using the actual volume or adding 10-15% to the calculated wattage.
