Das Wärme- und Wohnen-Panel zur Analyse des Wärmesektors: Ergebnisse der 3. Erhebung aus dem Jahr 2023
Diskussionspapier
In the summer of 2023, the third survey of around 15,000 households was conducted as part of the Ariadne heating and housing panel, which was established as part of the BMBF-funded Kopernikus project. The heating and housing panel combines information on the building stock and final energy demand with the socio-economic characteristics of the households living in the buildings. This article summarizes the main results of the third survey. One focus was on the implementation of twelve specific energy-saving measures that were mentioned to the respondents in the second survey so that they could arm themselves against the impending gas shortage and high energy prices in the winter of 2022. In the third survey, respondents were asked which of these twelve measures, which included switching off the heating when they were away and venting radiators, they had actually implemented. There was a strong discrepancy between the intention and the actual implementation. For example, 80.3% of respondents had planned to reduce the room temperature overnight, but 42.0% of those who had planned to do so said they had not implemented this measure 1. Another focus was on opinions on the Building Energy Act, which was the subject of much discussion during the survey. Among other things, participants were asked about their acceptance of a ban on the installation of new gas and oil heating systems from 2024. The overwhelming majority of participants rejected such a ban on installation. As the heat pump is seen as the heating technology of the future, heat pump owners were asked about their satisfaction with this heating technology. It emerged that around 20% of the more than 1,000 households heating with a heat pump are somewhat or very dissatisfied with it. The most common reason given was a sharp increase in electricity consumption as a result of heat pump use.
