The annual electricity consumption of a heat pump can vary significantly depending on several factors, including the type of heat pump, the size of the heat pump, the system efficiency, the insulation of the home, the climate, and the usage pattern. Therefore, it is difficult to provide an exact figure, but here are some general considerations:

1. Seasonal Coefficient of Performance (SCOP/SPF):

   • The seasonal coefficient of performance of the heat pump (SCOP/SPF) indicates how efficiently the heat pump operates throughout the year. A higher SCOP/SPF generally means more efficient operation and less electricity consumption.

2. Type of Heat Pump:

   • Air-to-air heat pumps and air-to-water heat pumps extract heat from the outside air and can be less efficient at lower outdoor temperatures. Ground-to-water and water-to-water heat pumps often perform better, especially in cold climates.

3. Insulation of the Home:

   • A well-insulated home requires less heating power, making the heat pump more efficient and potentially reducing annual electricity consumption.

4. Size of the Heat Pump:

   • A heat pump that is properly sized for the home's heating demand can operate more efficiently than an oversized or undersized heat pump.

5. Climate:

   • The climate in your region affects the efficiency of the heat pump. In colder climates, the heat pump may consume more energy to meet the heating demand.
