BTU Calculation Formula:
| From: | To: |
The BTU Calculator Top Radiator estimates the heat output capacity of top-mounted radiators using length, height, and a specific heat transfer factor. This calculation helps determine the appropriate radiator size for heating requirements.
The calculator uses the BTU calculation formula:
Where:
Explanation: The formula calculates the total heat output by multiplying the radiator's surface area by the heat transfer factor specific to top-mounted radiator configurations.
Details: Accurate BTU calculation is crucial for proper heating system design, ensuring adequate heat output for the space while optimizing energy efficiency and preventing undersizing or oversizing of radiators.
Tips: Enter radiator length and height in inches, and the appropriate heat transfer factor. The default factor of 150 BTU/in² is typical for top-mounted radiators, but consult manufacturer specifications for exact values.
Q1: What is the typical factor value for top-mounted radiators?
A: The standard factor is typically 150 BTU/in², but this can vary based on radiator material, design, and specific application requirements.
Q2: How accurate is this calculation method?
A: This provides a good estimate for standard applications, but for precise requirements, consult manufacturer data sheets and consider professional thermal calculations.
Q3: Can this calculator be used for other radiator types?
A: This calculator is specifically designed for top-mounted radiators. Other radiator types may require different factors and calculation methods.
Q4: What factors affect the heat transfer factor?
A: Material composition, fin design, water temperature, air flow, and installation conditions all influence the actual heat transfer performance.
Q5: How do I convert the result to other units?
A: 1 BTU/hr equals approximately 0.293 watts. For kW, divide BTU/hr by 3412. For tons of refrigeration, divide by 12,000.
