  "account": "As heating season approaches in Germany, many households anticipate higher heating costs due to the current high prices for oil and gas. According to the consulting firm co2online, oil heating costs are expected to rise by 24% in 2026 compared to last year, while the costs for oil-fired heating are projected to increase by 17%. Wärmepumpen (heat pumps), on the other hand, are projected to have a minimal increase in heating costs of just three percent. In fact, heat pumps were the most sold heating system in Germany for the first half of 2026, with 194,500 units sold. This was followed by gas heating systems with 134,000 units. The surge in popularity of heat pumps is primarily due to their significant energy efficiency, cutting heating costs by three percent. Germany has a large backlog of outdated heating systems, with the Bundesverband der Deutschen Heizungsindustrie (BDH) estimating that there are around four million heating systems older than 30 years. Around 40% of the 21.5 million heating systems in Germany are not up-to-date with current technology. The energy service provider Techem sees a lot of potential in retrofitting existing buildings, particularly multi-family dwellings. Installing heat pumps in multi-family dwellings, however, is more challenging due to the complex requirements for distance, noise, and other regulations. Many multi-family dwellings are owned by homeowner associations, which can make agreeing on a heating system replacement difficult. Therefore, many of these associations choose to repair the heating system instead of replacing it. The Techem study also examined the legal hurdles preventing the installation of heat pumps, but it focused more on the technical and economic feasibility of installing heat pumps. According to the study, even without replacing existing heating systems, about 40% of multi-family dwellings could be equipped with heat pumps. If owners replace old heating systems with modern low-temperature heating systems, the percentage rises to 90%. Installing heating systems is often more cost-effective than installing floor heating or insulating the external envelope of the building. The decision on which measures are suitable for a specific property should be made by an energy consultant after a site visit. Compared to other European countries, Germany has a high potential for installing heat pumps in multi-family dwellings. According to the Techem study, this potential is nearly 90% in Germany without heating system replacement, compared to only 14% in Switzerland without such replacement. Installing low-temperature heating systems would increase this figure to 68%. However, these potential figures cannot be directly compared across European countries, as Switzerland has already installed a quarter of its buildings with heat pumps, while Germany still has less than 10%. This explains the greater potential for heat pump installation in Germany.",
