The majority of private landlords surveyed rate the risk as extremely high (scores 8-10), as reliable municipal heating plans are lacking. ## Methodology A representative simulation by the Minds platform, aligned with data from the Statistisches Bundesamt, shows that 78 percent of private German landlords classify H2-ready heating systems as an incalculable financial risk and a potential investment trap due to unclear municipal heating plans and the strict 50-cent-per-square-meter cap on the modernization levy.**78**% Skepticism regarding H2 availability by 2044**84**% Concern over insufficient modernization levy**31**% Preference for heat pumps despite high initial costs Based on a simulated Audience of 700 respondent.

While owner-occupiers often benefit from generous government subsidies and individual transition periods, private landlords face immense economic pressure. They must balance statutory decarbonization requirements with the economic reality of their rental properties. Starting in 2026 or 2028, the obligation to use at least 65 percent renewable energy when replacing heating systems will take effect in almost all German municipalities, tied to the respective municipal heating plan. In this regulatory environment, H2-ready gas heating systems are often promoted by the industry as the ideal bridge technology. These devices can be operated with conventional natural gas today and theoretically converted to 100 percent hydrogen operation at a later date. However, the legal hurdles in the GEG are high: installation is only permitted if the respective municipality presents a binding transformation plan for a hydrogen network. If this plan is missing or if implementation by the network operator fails, the landlord faces forced decommissioning or an expensive retrofit after a transition period. For private landlords, who often own only a few residential units and do not have large capital reserves like institutional housing companies, this risk is existential. They simply cannot afford to rely on a technology whose future infrastructure is completely uncertain.DDieter Neumann, 58, EssenApartment building owner (6 residential units)H2-ready sounds nice on paper, but if no hydrogen flows in the end, I will be stuck with a worthless gas heating system and have to foot the bill alone because of the 50-cent cap. ## The Modernization Levy as an Amortization Brake A key driver of this skepticism is the discrepancy between the actual investment costs of modern heating systems and the legal options for refinancing them through rent. Although German tenancy law generally allows for a modernization levy, through which landlords can pass a portion of the costs onto the annual basic rent, the GEG has introduced a strict protective regulation for tenants: the levy for installing a new heating system is capped at a maximum of 50 cents per square meter of living space per month. This cap leads to an extreme extension of amortization periods. For example, if a landlord installs a highly efficient heat pump for 40,000 euros in a smaller apartment building, they can only increase the rent for a 60-square-meter apartment by 30 euros per month, even if the levy is fully utilized. Even taking into account government subsidies, which must be deducted before calculating the levy, a significant portion of the investment remains with the landlord. Amortization thus extends over decades, reducing the economic attractiveness of heat pumps in uninsulated existing buildings to almost zero. In this situation, the H2-ready gas heating system appears at first glance to be the only affordable alternative, as the acquisition costs are drastically lower compared to a heat pump. However, the fear of a stranded asset weighs heavily. Should the expansion of the hydrogen network fail, the landlord is left with nothing. They will have installed a heating system that they are no longer allowed to operate in the medium term, forcing them to invest again without ever having amortized the previous costs.SSabine Krawietz, 47, LeipzigPrivate landlord (3 apartments)The rent increase is capped at 50 cents per square meter. If I invest 40,000 euros in a heat pump now, it will never pay off. But H2-ready is an incalculable risk. ## H2-Ready: Bridge Technology or Marketing Illusion? The skepticism of private landlords is directed not only at the regulatory framework, but also at the technical and economic promises of hydrogen technology itself. Scientific studies and position papers from renowned energy agencies repeatedly point out that green hydrogen will remain a scarce and extremely expensive commodity in the building sector for the foreseeable future. Industry will be prioritized in the allocation of hydrogen, while only minimal residual quantities are likely to be left for decentralized space heating at astronomical prices. For landlords, this means a double risk: on the one hand, the danger that no hydrogen will be delivered at all, and on the other hand, the risk that operating costs for tenants will skyrocket due to extremely expensive hydrogen. Since the CO2 levy is split progressively between tenants and landlords, high fossil or expensive synthetic fuel costs also lead to a direct financial burden on the landlord. Upon closer inspection, the supposedly cheap H2-ready heating system turns out to be a potential cost trap for both sides. These complex concerns mean that the advertising messages of heating manufacturers, which promote H2-ready as a safe and future-proof solution, meet with massive distrust among the target group of private landlords. Claims emphasizing the simplicity of the transition are perceived as unrealistic and, in the worst case, as greenwashing.MMichael Brand, 52, NürnbergProperty manager & private ownerManufacturers promise us an easy bridge technology. But without a binding municipal heating plan, installing an H2-ready heating system is pure Russian roulette. ## Target Group Simulation as a Strategic Lever for Manufacturers For heating system (HVAC) manufacturers, it is crucial to precisely understand these deep-seated reservations and the complex economic trade-offs of their target group. However, traditional market research methods quickly reach their limits here. Recruiting private landlords for physical panels or focus groups is extremely time-consuming, expensive, and often yields only superficial answers that fail to capture the fine nuances of the GEG-tenancy law dilemma. Here, the target audience simulation platform Minds offers an innovative alternative. Minds enables marketing, insights, and innovation teams to simulate complex target group segments, such as private landlords in Germany, in precise detail. Instead of waiting weeks for the results of a traditional survey, Minds delivers deep, qualitative, and quantitative insights in under an hour. The platform is based on a scientifically grounded three-stage model that guarantees the highest level of data integrity and realism: 1. Data Grounding (Level 01): No persona or simulation is based on pure assumptions. Real market data, CRM data, internal studies, or traditional market research serve as the foundation. 2. Simulation Model (Level 02): At this level, Minds draws on deep consumer knowledge, demographic grounding, and robust behavioral models to precisely map the psychographic profiles of the target group. 3. Validation (Level 03): The simulation results are continuously validated against real survey data, panel results, and established reference benchmarks. This includes data from Kantar, Eurostat, and the Statistisches Bundesamt. Instead of rigid, proprietary milieu models, Minds uses validated demographic and psychographic segmentation models to realistically map actual consumer behavior. The accuracy of Minds simulations is remarkable: on average, a correlation of 85 to 95 percent is achieved with traditional, physical panels. For specific questions and well-grounded segments, the correlation can even reach up to 100 percent. Furthermore, the platform is 100 percent GDPR-compliant, as all simulations are hosted on secure servers within the European Union and no personal data of real participants is processed. By using Minds, heating manufacturers can test their marketing claims, positioning strategies, and product concepts in advance without risking valuable budget, time, or market trust in risky field trials. They can simulate exactly how private landlords react to arguments such as future-proofing, H2-ready, or amortization benefits, and calibrate their messaging to address the real pain points and legal concerns of the target group. This is done at a fraction of the cost of a traditional panel and completely without the usual recruitment costs per participant.
