Michael Penn-Juneau Empire Photo Photo Credit: NOAA - One of two heat pumps that extract 4 degrees of heat from 38-degree seawater and use that energy to heat the 66,000-square foot Ted Stevens Marine Research Institute in Juneau, Alaska. Coefficient of Performance of a Seawater Heat Pump The Coefficient of Performance (COP) for a heat pump is the ratio of total heat output to electricity input. For this seawater heat pump project, a minimum COP value of 3.0 can be maintained and will lead to viable economic returns. This COP is maintained because there is enough heat stored in the thermal mass of Southeast Alaska sea water through the winter heating season to keep seawater temperatures well above freezing. This heat can be captured as renewable energy using the emerging technology heat pumps now available. The seawater heat pump process and associated COP is illustrated below: 5PDF Image | Heat Pump Technology
