Heating Model (3PH)
Fit a change-point heating model to monthly energy use: E = b + w_d · max(T_c − Tₐ, 0). Enter your months of average temperature and energy, then fit for the base load, weather slope, and balance-point temperature.

The base load b is the weather-independent use; the slope is kWh per °F per month below the changepoint. °C inputs are converted to °F internally. For the best fit, include both mild and cold months. Runs entirely in your browser.
