BTU Calculation Formula:
| From: | To: |
The BTU Calculator for Radiators estimates the heat output required for a room based on its area and radiator type. BTU/h (British Thermal Units per hour) measures heating capacity, helping select the right radiator size for efficient heating.
The calculator uses the BTU calculation formula:
Where:
Explanation: The type factor accounts for different radiator efficiencies and room insulation levels, with higher factors for rooms requiring more heating capacity.
Details: Accurate BTU calculation ensures proper radiator sizing, preventing underheating (insufficient warmth) or overheating (energy waste). It optimizes comfort and energy efficiency in residential and commercial spaces.
Tips: Enter room area in square feet and select appropriate type factor based on room type and insulation. Standard (200) for well-insulated rooms, Medium (250) for average insulation, High (300) for poorly insulated or high-heat-loss areas.
Q1: What is BTU and why is it important for radiators?
A: BTU measures heat output capacity. Proper BTU calculation ensures your radiator can adequately heat the room space.
Q2: How do I determine the right type factor?
A: Consider room insulation, window area, and climate. Use higher factors for rooms with large windows, poor insulation, or in colder climates.
Q3: What are typical BTU requirements per room size?
A: Small rooms (100-150 ft²): 5,000-10,000 BTU; Medium rooms (150-250 ft²): 10,000-15,000 BTU; Large rooms (250-400 ft²): 15,000-25,000 BTU.
Q4: Should I add extra BTU capacity?
A: Add 10-20% extra for rooms with high ceilings, large windows, or in very cold climates to ensure adequate heating.
Q5: Can this calculator be used for all radiator types?
A: Yes, it works for panel radiators, column radiators, and convector radiators, though specific models may have different efficiency ratings.
