Heat Pump vs Gas Planner (Netherlands)
Probabilistic comparison with weather-driven COP. Daily temperatures are sampled per province (KNMI 1991-2020 normals) so cold spells naturally reduce heat-pump efficiency. Positive values mean the heat pump is cheaper (savings).
Home and Energy demand
Space heating is weather-distributed by daily degree-days. In gas mode, summer usage estimates hot water share and the remainder is assigned to space heating.
