1. What is a Radiator Calculator for Room Size?

Definition: This calculator estimates the required radiator power in kilowatts based on the 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 power (kilowatts)
• \( A_{room} \) — Room area (square meters)

Explanation: The formula converts the heat requirement (44.6 BTU per square meter) to kilowatts (1 kW = 3412 BTU/hr).

3. Importance of Proper Radiator Sizing

Details: Correct radiator sizing ensures efficient heating, energy savings, and comfortable room temperatures without overheating or underheating.

4. Using the Calculator

Tips: Simply enter the room area in square meters. The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: Is this calculation suitable for all room types?
A: This provides a basic estimate. Bathrooms may need 10-20% more power, while well-insulated rooms may need less.

Q2: What's the 44.6 value in the formula?
A: This represents the standard heat requirement of 44.6 BTU per square meter for a moderately insulated room.

Q3: Should I round up the radiator size?
A: Yes, it's recommended to round up to the nearest available radiator size for better performance.

Q4: Does this account for room height?
A: The standard calculation assumes 2.4m ceiling height. For higher ceilings, multiply the result by (actual height/2.4).

Q5: What about rooms with large windows?
A: Add 10% to the calculated power for each large window or French door in the room.
