Introduction: Efficient furnace operation requires a well-sized flue to ensure proper ventilation and safety. The Furnace Flue Size Calculator is a valuable tool designed to provide personalized recommendations based on the furnace BTU (British Thermal Units) and the flue gas temperature. Whether you’re upgrading your furnace or planning a new installation, this calculator ensures that your furnace flue is appropriately sized for optimal performance.
Formula: The Furnace Flue Size Calculator uses a formula that considers the furnace BTU and the flue gas temperature. The calculation divides the furnace BTU by the ratio of the flue gas temperature to 100. This ensures that the recommended flue size aligns with the specific ventilation needs of your furnace.
How to Use:
- Enter the furnace BTU in British Thermal Units.
- Enter the flue gas temperature in degrees Fahrenheit.
- Click the “Calculate” button to receive a personalized recommendation for the ideal furnace flue size.
Example: Suppose you input a furnace BTU of 80,000 and a flue gas temperature of 400 degrees Fahrenheit. The calculator processes this information and provides an instant result, recommending the ideal furnace flue size for your specific requirements.
