1. What is a Room Size Radiator Calculator?

Definition: This calculator estimates the required radiator size in kilowatts (kW) 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:

\[ P_{kW} = \frac{A_{room} \times 44.6}{3412} \]

Where:

\( P_{kW} \) — Radiator size in kilowatts (kW)
\( A_{room} \) — Room area in square meters (m²)
44.6 — Standard heat requirement in BTU per square meter
3412 — Conversion factor from BTU to kW

Explanation: The room area is multiplied by the standard heat requirement and then converted from BTU to kW.

3. Importance of Radiator Sizing

Details: Proper radiator sizing ensures efficient heating, energy savings, and comfortable room temperatures without oversizing.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What if my room has large windows?
A: For rooms with large windows or poor insulation, consider adding 10-20% to the calculated radiator size.

Q2: Does this work for all room types?
A: This provides a general estimate. Bathrooms and kitchens may require adjustments based on specific needs.

Q3: What's the standard heat requirement of 44.6 BTU/m² based on?
A: This is a general value for moderately insulated rooms in temperate climates.

Q4: How do I convert the result to BTU?
A: Multiply the kW result by 3412 to get BTU/h.

Q5: Should I round up the radiator size?
A: Yes, it's common practice to round up to the nearest available radiator size.
