The Green Party has warned that the German government is proposing too many changes to the heating law. Michael Kellner, spokesperson for the Greens’ Energy Policy Group, told the “Rheinische Post” (Friday edition) that abolishing the current 65‑percent renewable‑energy requirement would deepen the country’s dependence on fossil fuels and trap homeowners in a price trap should gas network charges rise.
Kellner added that heating contractors are far ahead of the government: both industry and the trade sector are ready for a modernization push. He stressed that when it comes to heating, Germany should no longer rely on gas supplied by Trump’s or Putin’s governments.
Industry leaders are urging policymakers to act quickly. Martin Sabel, managing director of the German Heat Pump Association, told the paper that the federal government must keep sensible and effective rules in place. He noted that in 2025 the heat pump was the most sold heating system, indicating that the craft, industry and many consumers had already adapted to the existing Building Energy Act. Sabel sees the building sector as offering substantial potential for economic growth rooted in domestic value creation.
In the coalition agreement between the Schwarz and Rot parties, the parties agreed to scrap the current heating law and replace it with a Building Modernisation Act. The main feature of the old heating law was the requirement that 65 % of heating energy come from renewable sources. Whether this 65‑percent target will remain in the new Building Modernisation Act remains a point of contention.
