Your questions, our answers
How is the heat supply in Mainz developing? Which heating systems will play a role in the future? Are there any funding opportunities?
Our FAQ provides concise answers on municipal heat planning and its objectives.
What heating systems will there be in the future?
Various renewable energy technologies such as heat pumps, solar thermal energy, district heating, and geothermal energy are taken into account. The exact selection depends on local conditions and the availability of resources. An overview of possible heating technologies can be found here (opens in a new tab).
How does heat planning affect me as a citizen?
The municipal heating plan shows which climate-friendly heating supply options are available in Mainz. As a citizen, you are not directly obligated to do anything, but the plan provides guidance—for example, on heating networks, heat pumps, or funding opportunities. For property owners in particular, it can be a valuable basis for decisions on future investments.
What can I contribute to heat planning as a resident of Mainz?
You can actively seek information, participate in public events, and contribute suggestions or concerns. You can also check whether your own heating system is efficient and can already be converted to renewable energies.
Will there be an obligation to connect to the heating network in Mainz?
In the Mainz-Lerchenberg area, connection to the heating network has been mandatory since 1984. Whether mandatory connection to an expanded or new heating network will be introduced in the future depends on various factors—for example, how economical and reliable a heating network would be in certain areas.
The city is examining various options for heat supply in its municipal heat planning. If a mandatory connection were to make sense in some areas, the city council would have to decide on it. Currently, there is no basis for a decision on this.
Can I continue to use my existing heating system and what do I need to bear in mind when replacing it?
Yes, existing heating systems may generally continue to be used. However, there are requirements that must be observed when replacing or repairing them. These are regulated by the Building Energy Act (GEG). Information on this can be found, for example, at the Consumer Advice Center (opens in a new tab).
Where can I get advice on heating and refurbishment?
The city of Mainz offers consulting services in cooperation with the Rhineland-Palatinate Consumer Advice Center. Here you will find further links to energy consulting services. These will help you find the best solution for your building.
Is there financial support for switching to climate-friendly heating systems?
Yes, there are various federal and state subsidy programs that support the switch to renewable energies or energy-efficient heating systems. You can find the latest developments and information on subsidies at www.energiewechsel.de (opens in a new tab).
How can I find out about the status of heat planning in Mainz?
The state capital of Mainz will provide regular updates on the progress of its heating plan, e.g. through information events or this website. You can also contact waermeplanungstadt.mainzde directly.
How are municipal heating planning and the heating master plan 2.0 connected?
Municipal heat planning builds on the results of Heat Master Plan 2.0. The results are expanded, detailed, and supplemented with input from local stakeholders (e.g., with a waste heat register). You can find detailed information about Heat Master Plan 2.0 on the Mainz public utility company website (opens in a new tab).
