Radiator Size Formula:
| From: | To: |
Radiator size calculation determines the appropriate heating capacity in BTU (British Thermal Units) needed to effectively heat a room based on its volume and insulation quality.
The calculator uses the radiator size formula:
Where:
Explanation: The formula accounts for room size and insulation quality to determine the heating capacity required for optimal comfort.
Details: Correct radiator sizing ensures efficient heating, prevents energy waste, maintains comfortable room temperatures, and extends heating system lifespan.
Tips: Enter room volume in cubic meters and select insulation factor based on your room's insulation quality. Room volume must be greater than 0.
Q1: What is BTU and why is it important?
A: BTU (British Thermal Unit) measures heating capacity. Proper BTU calculation ensures your radiator can adequately heat the room.
Q2: How do I calculate room volume?
A: Multiply room length × width × height in meters. For example: 4m × 5m × 2.4m = 48m³.
Q3: What insulation factor should I choose?
A: 25 for new/well-insulated rooms, 30 for average insulation, 35 for older/poorly insulated rooms or rooms with large windows.
Q4: Are there other factors to consider?
A: Yes, consider window size, room orientation, number of external walls, and ceiling height for more accurate sizing.
Q5: Can I use this for whole house calculations?
A: Calculate each room separately as insulation and heating requirements vary by room.
