BTU/h Formula:
| From: | To: |
The Hot Water Boiler BTU Calculator estimates boiler output in BTU per hour based on water flow rate and temperature rise. This calculation is essential for sizing boilers and understanding heating system capacity.
The calculator uses the BTU/h formula:
Where:
Explanation: The formula calculates the energy required to heat water based on flow rate and temperature difference, where 1 BTU is the energy needed to raise 1 pound of water by 1°F.
Details: Accurate BTU calculation is crucial for proper boiler sizing, energy efficiency optimization, and ensuring adequate heating capacity for building requirements.
Tips: Enter flow rate in gallons per minute and temperature rise in degrees Fahrenheit. All values must be positive numbers greater than zero.
Q1: What does BTU/h stand for?
A: BTU/h stands for British Thermal Units per hour, which is a measure of heating or cooling capacity.
Q2: Why is 8.33 used in the formula?
A: 8.33 represents the weight in pounds of one gallon of water at standard conditions.
Q3: What is a typical temperature rise for boilers?
A: Typical temperature rises range from 20°F to 40°F, depending on the system design and application.
Q4: Can this calculator be used for chilled water systems?
A: Yes, the same formula applies for cooling calculations, where ΔT represents the temperature drop.
Q5: How accurate is this calculation?
A: This provides a good estimate for standard water conditions. For precise engineering calculations, additional factors like water density variations should be considered.
