# Heat-pump input and output
# Scope: Supplied seasonal or operating COP; no refrigerant cycle simulation.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

heatDemand = 3000 W
cop = 3
duration = 8 h

input := heatDemand/cop [W]
energy := input*duration [kWh]

check electrical energy budget: energy <= 10 kWh

scenario alternative: heatDemand = 2400 W
