Heat pump control simulator

Dynamic heat pump simulator

Explore continuous vs intermittent heating, temperature set-backs and schedules.

This tool is work in progress. It does not yet implement minimum modulation or take into account defrosts and so will over estimate performance in certain cases. Help welcome to make this tool better.
