Germany Reverses Course on Heating Law: What’s Changing and Why
A new agreement between the CDU/CSU and SPD coalitions in Germany will significantly alter the country’s approach to heating systems in homes. The central requirement of the previous “heating law” – mandating that new heating systems operate with at least 65% renewable energy – has been scrapped. This marks a major shift from the policies enacted by the previous “traffic light” coalition (SPD, Greens, and FDP).
The Demise of the 65% Renewable Energy Rule
The previous law, often referred to as the “Habeck heating law” after former Green Economics Minister Robert Habeck, aimed to gradually replace oil and gas heating systems with more climate-friendly alternatives. The new agreement, however, removes this mandatory requirement. According to CDU faction leader Jens Spahn, “All types of heating are possible again.”
A “Green Gas” Quota to Drive Emissions Reduction
Although the 65% rule is gone, the coalition intends to achieve climate goals through a “green gas quota.” This involves gradually increasing the proportion of biomethane mixed with natural gas. A quota of up to 1% is planned for 2028, rising to 10% for newly installed fossil fuel heating systems by 2029. No CO₂ tax will be levied on the climate-friendly components of this mix, incentivizing the transition.
Easing the Burden on Homeowners
The new legislation aims to give homeowners more freedom in choosing their heating systems. The requirement to replace existing, functional heating systems is being removed. The advisory requirement for heating system replacements will also be abolished. The government emphasizes that the decision regarding future heating systems will rest with property owners.
Continued Support for Climate-Friendly Options
Despite the shift away from mandates, financial support for climate-neutral heating systems will continue at least until 2029, according to SPD faction leader Matthias Miersch. This support is intended to maintain momentum towards climate goals while providing flexibility for homeowners.
Changes to Municipal Heat Planning
The requirements for municipal heat planning are also being adjusted. Smaller communities with fewer than 15,000 residents will face simplified data collection requirements, easing the administrative burden.
Timeline for Implementation
The coalition aims to finalize a draft bill by Easter (early April) and have it approved by the Bundestag by July 1st. This ambitious timeline suggests a swift implementation of the revised heating law.
Frequently Asked Questions
What is the “green gas quota”?
It’s a system where biomethane is mixed with natural gas, gradually increasing the proportion of renewable energy in the gas supply.
Will I be forced to replace my existing heating system?
No, the new law will not mandate the replacement of existing, functional heating systems.
What is the “Biotreppe”?
The “Biotreppe” refers to the planned gradual increase in the bio-content of gas used in heating systems.
This shift in policy represents a significant change in Germany’s energy transition strategy, prioritizing homeowner choice and flexibility while still aiming to reduce carbon emissions. The success of this approach will depend on the effectiveness of the green gas quota and continued support for climate-friendly heating technologies.
