COP - Heating (Heat Pump)
Heat-pump COP: useful condenser duty / compressor work. COP_heat = COP_cool + 1 in an ideal cycle.

Formula, assumptions, and limits
Air-to-water heat pumps for cabin heating: COP 3–4 at +7 °C source, 2–2.5 at −10 °C. R-744 transcritical heat pumps achieve COP 3+ at −20 °C source in polar operation.
