Calculateur de Heat Loss
Estimate heat loss from U-value, area, and temperature difference.
Formula and method
This calculator computes Heat loss directly in your browser without sending data to an external server.
Mathematical formula
- Heat loss:
u × area × delta
Variables and parameters
- U-value (u): default value 0.3 BTU/h-ft²-F.
- Area (area): default value 200 ft².
- Temperature difference (delta): default value 40 °F.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
