Effects of sectoral coupling in the heating sector on the energy costs of private consumers

With increasing electrification and the coupling of the electricity and heat sectors, which will increase in the future, the energy mix of the building supply and thus the energy costs that consumers have to pay for the heat supply (space heating and domestic hot water) are changing. For this purpose, the annual energy costs of different heating options for different household types are calculated and compared for the target year 2030. The investigation focuses in particular on current energy costs (e.g. fuel costs for heating oil and natural gas, electricity costs for running heat pumps) as well as the costs for the various heat supply technologies with different forms of electrification of the heat supply (mainly through heat pumps).
