Heat pump calculators

Open source tools to help with heat pump design and understanding.

Heat exchanger 1

Calculate heat output and COP for a system with a counterflow plate heat exchanger between the heat pump and the radiator system. Fixed flow temperature version.

Heat exchanger 2

Calculate heat output and COP for a system with a counterflow plate heat exchanger between the heat pump and the radiator system. Improved fixed heat output version.

Low loss header

Calculate heat output and COP for a system with a low loss header between the heat pump and the radiator system. Fixed heat output.

SCOP calculator

Calculate heat pump SCOP based on design flow temperature.

Dynamic heat pump simulator

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