Experts will provide information on technology, costs and funding on November 16th – additional date in Seeheim-Jugenheim
How economically do modern heat pumps operate? What are the investment costs, and how do the systems perform in daily use? A workshop hosted by the town of Riedstadt on Monday, November 16, 2026, from 7:00 to 8:30 p.m. at the town hall in Goddelau will provide answers to these questions. Under the title "Heat Pumps in Practice – Technology, Costs, Examples," experts will discuss technical fundamentals, funding opportunities, and practical experience. The day before, in Seeheim-Jugenheim, there will be an opportunity to see a heat pump in action in conjunction with a particularly energy-efficient building.
Both events are free of charge. Registration is not required.
Technology and economic efficiency are the focus
Switching to more climate-friendly heating technologies presents many homeowners with important decisions. Especially in existing buildings, the question arises whether a heat pump can be used in a technically and economically viable way.
At the Riedstadt workshop, Rudolf Bersch explains the fundamentals of modern heat pump technology. This includes, among other things, how the systems work and the factors that influence their efficiency.
An important indicator is the so-called seasonal performance factor (SPF). It describes the ratio between the amount of heat generated over a year and the electricity required to produce it. The higher this value, the more efficiently the system operates.
Furthermore, the economic framework is considered. Bersch provides information on potential investment costs, ongoing expenses, and current funding opportunities.
First municipal heat pump at the Crumstadt sports field
Renovation manager Benjamin Krick then demonstrates how the technology proves itself in practical operation using a concrete example from Riedstadt.
A heat pump was installed in a municipal building for the first time at the Crumstadt sports field. The experience gained there should provide insights into which technical and economic aspects need to be considered in comparable projects.
This allows participants to receive not only theoretical information, but also insights into an already implemented system.
Pilot project aims to reduce investment costs
Another topic is the project “Heat pumps in the neighborhood”, in which Riedstadt is participating as a model municipality.
The project, funded by the German Federal Environmental Foundation, aims to significantly reduce investment costs for heat pumps.
Benjamin Krick presents the project and explains the approaches being pursued.
Following the presentations, there will be ample opportunity to ask individual questions, exchange ideas with the experts, and, if necessary, discuss specific individual cases.
The event is being held in cooperation with the Hessian Consumer Center and is funded by the Federal Ministry for Economic Affairs and Energy.
Additional appointment in Seeheim-Jugenheim: Insulating with straw
Another workshop discussion will take place on Sunday, November 15th, as part of the "Open Days in the Passive House".
Under the title "Insulating with straw, heating with heat pumps", the focus is on the combination of sustainable building materials and modern heating technology.
From 2 p.m. onwards, the house of renovation manager Benjamin Krick in Seeheim can be visited. Visitors will gain insights into a building where straw is used as insulation and a heat pump is used for heating.
At 4 p.m. an accompanying technical lecture will begin, which will explain the technical context and practical experiences in more detail.
Participation in this event is also free and possible without prior registration.
