Power consumption of a heat pump
A heat pump needs electricity to utilise its energy sources water, air and geothermal energy efficiently. Nevertheless, the heat pump is a cost-effective and future-orientated investment in the long term. The actual electricity consumption of a residential property can be calculated individually.
Facts about energy consumption of a heat pump
Energy from the environment instead of fossil fuels
Low power demand for operation
Minimise CO2 emissions with green electricity
Independence from the energy market thanks to the combination with photovoltaics
Cost-effective and sustainable despite power consumption
Heat pumps draw up to 80% of their energy free of charge from the environment. This means from the air, ground or water. The remaining approximately 20% is taken from a power socket. This means that although heat pumps require electricity, they obtain the majority of their heat energy requirements from renewable sources. The electricity that comes out of the socket can be green electricity if desired. This makes the heat pump an economically and sustainably sensible solution from an overall perspective.
Varies from case to case
The annual electricity consumption of a heat pump depends on various factors and is therefore difficult to calculate. How many people live in the household and use hot water accordingly? Should the room temperature be 19 or 24 degrees Celsius in winter? How well insulated is the house? What type of heat pump will be used? Where is the heat pump located geographically? What is the weather like this year? Would you like to estimate the annual electricity costs that your future heat pump will generate? Multiply the expected electricity consumption by the electricity price:(annual heat requirement in kWh / COP* of the heat pump) × electricity price per kWh = electricity costs per year * COP = Coefficient of Performance: Efficiency measured in the laboratory at a specific operating point. The efficiency of a heat pump is particularly evident in comparison with other heating systems. On the platform Erneuerbar Heizen, comparisons can be made between oil, gas, heat pumps and other types of heating.
