Heat Pump efficiency is measured as Coefficient of Performance (COP). For instance a baseboard electric heater has a COP of 1 (it is 100% efficient). Geothermal Heat Pumps in the Northeast have COPs of 3 to 5 (300 to 500%)* efficient.

* For every 1 unit of electric energy purchased, you can get 3 to 5 units of heat from a properly installed ClimateMaster™ Heat Pump.
