Federal Minister Katherina Reiche emphasized a ‘restart of the heating transition’ by promoting technology openness and individual responsibility, contrasting sharply with the previous coalition’s stringent regulations on new heating systems. Critics, including representatives from the Green Party and the Left, condemned the law for undermining climate goals and expressed intentions to challenge it legally, citing concerns over its practicality and potential negative impacts on citizens and municipalities. The law introduces a phased requirement for the inclusion of climate-friendly components in heating systems, which opponents argue may not be feasible.
