Calculation method
Calculation method
Mixed-water volume (litres)
Constant-temperature ideal mixing fraction = (mixed−cold)/(hot−cold), integrated over supplied draw intervals.
Stored hot-water volume (litres)
Constant-temperature ideal mixing fraction = (mixed−cold)/(hot−cold), integrated over supplied draw intervals.
Interval hot-water volumes (JSON)
Constant-temperature ideal mixing fraction = (mixed−cold)/(hot−cold), integrated over supplied draw intervals.

Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Constant-temperature ideal mixing fraction = (mixed−cold)/(hot−cold), integrated over supplied draw intervals. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
