How Does the Calculator Work?

The calculator functions by employing a fundamental principle of heat transfer: A = Q / (V * ΔT). The user inputs the required values into the fields, and the calculator outputs the optimal coil surface area. The user-friendly interface and detailed instructions make it simple to use for both professionals and novices.

The Mathematical Formula

The formula used is A = Q / (V * ΔT), where 'A' denotes coil surface area (in square feet or square meters), 'Q' represents heat transfer rate (in BTU/hr or Watts), 'V' refers to the flow rate of hot water (in gallons per minute or liters per minute), and 'ΔT' is the temperature difference (in degrees Fahrenheit or Celsius).
