1. What is a Radiator Size Calculator?

Definition: This calculator estimates the required radiator size in kilowatts (kW) based on room area in square meters.

Purpose: It helps homeowners and heating professionals determine the appropriate radiator size for efficient room heating.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Radiator size (kilowatts)
• \( A_{room} \) — Room area (square meters)

Explanation: The formula calculates the heat output needed based on standard heating requirements (44.6 BTU per square foot converted to kW).

3. Importance of Proper Radiator Sizing

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

4. Using the Calculator

Tips: Simply enter the room area in square meters. The calculator will determine the recommended radiator size in kilowatts.

5. Frequently Asked Questions (FAQ)

Q1: What's the 44.6 factor in the formula?
A: This represents the standard British Thermal Unit (BTU) requirement per square foot (converted to metric).

Q2: Should I round up the radiator size?
A: Yes, it's recommended to round up to the nearest available radiator size for better performance.

Q3: Does this account for room insulation?
A: No, this is a basic calculation. Poor insulation may require a larger radiator.

Q4: What about room height?
A: Standard calculations assume 2.4m ceilings. For higher ceilings, multiply the result by (your ceiling height/2.4).

Q5: How accurate is this calculation?
A: It provides a good estimate for standard rooms. For precise calculations, consult a heating professional.
