Formula

COP_heating = T_hot / (T_hot − T_cold)

Temperatures must be absolute (K)

How to Use

  1. Enter hot-side absolute temperature T_hot (K).
  2. Enter cold-side T_cold (K).
  3. Get heating COP.

Case Studies

300 K / 270 K

COP = 300/(300−270) = 10.

FAQ

Real COP is lower?

This is the ideal upper bound; real units lose to compression and thermal losses.
