BTU Calculation Formula:
| From: | To: |
The Propane Heater BTU Calculator estimates the heat output of propane heaters by converting propane flow rate to British Thermal Units per hour (BTU/h). This helps determine heating capacity and efficiency for various propane heating applications.
The calculator uses the BTU calculation formula:
Where:
Explanation: The formula multiplies the propane flow rate by the standard heating value of propane (915 BTU per cubic foot) to determine the total heat output.
Details: Accurate BTU calculation is essential for sizing propane heaters appropriately for different spaces, ensuring efficient heating, preventing energy waste, and maintaining safety standards.
Tips: Enter propane flow rate in cubic feet per hour (CFH). The value must be greater than zero. The calculator will automatically compute the BTU output based on the standard propane heating value.
Q1: What is the heating value of propane?
A: Propane has a heating value of approximately 915 BTU per cubic foot, which is the standard value used in this calculation.
Q2: How do I measure propane flow rate?
A: Propane flow rate can be measured using flow meters or calculated based on appliance specifications and operating conditions.
Q3: What factors affect BTU output?
A: BTU output can be affected by propane purity, altitude, temperature, and appliance efficiency. This calculator uses standard conditions.
Q4: How do I size a propane heater for my space?
A: Generally, you need 20-30 BTU per square foot for heating. Use this calculator to verify if your propane flow rate provides adequate heating capacity.
Q5: Is this calculation accurate for all propane heaters?
A: This provides a theoretical maximum based on propane's energy content. Actual output may vary based on heater efficiency and specific design.
