MYHOME REAL ESTATE - THE ORIGINAL SINCE 2014
Anyone who owns a property in Neumarkt i.d.OPf. or the neighboring Frankenjura region and wants to avoid using fossil fuels for heating will find geothermal energy to be a technically mature alternative. Due to its geology, Franconia offers varying geothermal potential-ranging from well-suited carbonate rock layers in the Jura to less productive sedimentary areas. The LfU Geothermal Atlas of Bavaria provides the essential basis for planning.
Geologically, Franconia is characterized by the Franconian Jura-a Jurassic limestone belt stretching from Kelheim through Eichstätt to Amberg, with Neumarkt i.d.OPf. at its center. This rock formation directly influences geothermal potential.
The Bavarian State Office for the Environment (LfU) operates the free online Geothermal Atlas of Bavaria, which provides data on the usable heat extraction capacity of geothermal probes for every municipality in the state. For the Neumarkt region, the atlas indicates average specific heat extraction rates of 40-55 W/m of probe length in carbonate rocks-a value that makes geothermal probe systems economically attractive. By comparison: In the Nuremberg Basin (sandstone), the values range from 35-45 W/m.
The geothermal heat flux in Franconia is approximately 65-80 mW/m², which reflects average Bavarian conditions. The temperature rises to about 12-14 °C at a depth of 100 m and to 16-20 °C at a depth of 200 m. These temperatures are sufficient to operate brine-water heat pumps efficiently-with an annual performance factor (APF) of 4.0-5.0 under optimal conditions.
| System Type | Drilling Depth (m) | Investment Cost (€) | BAFA Subsidy Rate | Payback Period (Years) |
|---|---|---|---|---|
| Brine Heat Pump for Single-Family Home (8 kW, 1 probe) | 80-100 | 20,000-28,000 | 30-35% | 12-18 |
| Brine heat pump, single-family home (12 kW, 2 probes) | 2 × 80 | 30,000-40,000 | 30-35% | 14-20 |
| Brine heat pump, multi-family home (30 kW, 4 probes) | 4 × 100 | 65,000-95,000 | 30-35% | 14-22 |
| Ground collector (area 300 m²) | 1.2-1.5 | 12,000-20,000 | 30-35% | 10-15 |
| Groundwater heat pump for single-family home (8 kW) | 15-30 | 18,000-26,000 | 30-35% | 10-14 |

Since the 2024 reform, the BAFA basic subsidy for heat pumps (BEG EM, individual measure) has ranged between 30 and 40 percent of eligible costs, depending on the type of heating system, the outdoor air temperature, and the income bonus. Due to their high annual performance factor, geothermal probe heat pumps generally achieve the maximum subsidy rates. In addition, there is the KfW supplementary loan (Program 358/359), which allows for low-interest financing of equity capital.
Anyone planning a geothermal probe system in Neumarkt must go through several mandatory steps. According to the Bavarian Water Act (BayWG), drilling is considered an intervention relevant under water law and requires a permit.
Preliminary Review: First, it must be determined whether the property is located in a water protection area. The Neumarkt i.d.OPf. District Office (Water Law Division) provides this information free of charge. Geothermal energy is prohibited in water protection areas of Zones I and II; stricter requirements apply in Zone III.
LfU Atlas and Geological Survey Cadastre: The LfU Geothermal Atlas shows at the parcel level whether drilling is permitted. The Bavarian Geological Survey Cadastre documents existing boreholes-relevant for complying with distance requirements (minimum distance of 10 m between boreholes owned by different parties).
Water Law Permit: For depths under 100 m, a simplified notification is often sufficient; for deeper drilling, a water law permitting process is required. The process typically takes 4-12 weeks.
Technical Planning: A drilling contractor certified according to DVGW W 120 must be commissioned. There are several licensed companies in the Neumarkt region; the Chamber of Crafts of Middle Franconia maintains an up-to-date list.
Heating load calculation and system design: In parallel with the permitting process, a heating contractor should perform a heating load calculation in accordance with DIN 12831. This calculation determines the required heat pump capacity and the necessary probe length. For a single-family home built between 1960 and 1980 in Neumarkt, the heating load without insulation is often 10-15 kW-after adding facade insulation and a new roof, it drops to 6-10 kW, making the system smaller and more cost-effective.
Hydraulic balancing as a mandatory component: Anyone installing a geothermal heat pump must have a hydraulic balancing procedure (Method B) performed in accordance with GEG § 60a and as a prerequisite for BAFA funding. Without balancing, neither the BAFA grant nor the KfW supplementary loan can be obtained. The costs for the balancing (300-700 euros for a single-family home) are recognized as eligible ancillary costs.
BAFA Application Before Contracting: The BAFA subsidy application for the heat pump must be submitted and approved before placing the order with the installation company. Submitting the application early via the BAFA online portal (bundesfoerderung.de) secures your eligibility for the subsidy-processing time is currently 4-8 weeks.

The Neumarkt i.d.OPf. region is located within the Upper Palatinate Jura, a karst area characterized by sinkholes and underground watercourses. This karst hydrology has direct implications for geothermal drilling: In karst areas, drilling fluid can seep into the groundwater, which poses a problem under water protection laws. The LfU Bavaria has therefore developed specific reference maps for karst areas in Northern Bavaria, which must be consulted before drilling.
The Neumarkt area benefits from several significant groundwater resources that secure the region’s drinking water supply. The network of protection zones is correspondingly dense: A considerable portion of the municipal areas in the Neumarkt district lies within Zone III water protection areas, which, while not precluding drilling, entails more extensive sealing measures and monitoring requirements.
At the same time, the Jura limestones outside of karst areas offer very good conditions for geothermal probes. In the new development areas on the western outskirts of Neumarkt and in the villages of Pölling and Mühlhausen, geothermal probes are regularly used by builders. Experience shows that the permitting procedures there are less complicated than in the historic settlement areas near the city center.
Around Neumarkt City Palace and in the historic city center, those interested in geothermal energy encounter narrow lots and dense development-there, the ground-source collector (horizontal geothermal collector) is often not an option, and deep drilling requires space for the drilling rig (minimum setup area 10 × 5 m). In terms of soil conditions, the Jura formation near the old town sometimes features rock layers at depths of less than 5 m-which increases drilling costs, as rock cutters must be used instead of rotary drilling.
The Neumarkt Energy Cooperative (one of the most active energy initiatives in the district) advises property owners on geothermal projects and facilitates contacts with licensed drilling contractors. Such regional networks significantly shorten planning times and are a unique selling point for Neumarkt when compared to other regions.
Geothermal heating systems increase property value in two ways: directly through the system itself and indirectly through the improved energy efficiency rating on the energy performance certificate. A single-family home in Neumarkt that converts from oil/gas heating to a geothermal heat pump typically improves its energy efficiency rating by two to three levels-from F/G to C/D, or to B if insulation is installed at the same time.
According to the Real Estate Valuation Committee for the Neumarkt district, the value premium for energy-efficiently renovated single-family homes (classes A to C) compared to comparable buildings in classes E to G is 8-15 percent. At an average price of €2,800/m² in Neumarkt (source: Neumarkt Expert Committee 2025), this corresponds to an added value of €33,600-63,000 for a 150 m² living area.
Investing in a geothermal heating system (out-of-pocket cost after subsidies: €13,000-€26,000) can therefore be worthwhile from a purely real estate perspective-especially if a sale is planned within the next 5-10 years.
Important for the market outlook: Starting in 2027, the GEG tightening package will take effect, making renovation roadmaps (iSFP) mandatory for sales of certain building classes. A house that already has a geothermal heat pump and achieves energy class D or better generally falls outside the mandatory renovation category-which significantly increases its marketability. Prospective buyers in the 35-50 age group now routinely ask about the heating system as the first question during a property viewing.
For landlords of multi-family homes, there is an additional factor: The CO2 Cost Allocation Act (CO2KAG) requires landlords to bear a portion of the CO2 costs starting in 2023. With a geothermal heat pump, these costs are eliminated entirely-which noticeably reduces operating costs for tenants and owners and makes the net rent more stable in the long term.
Franconia offers solid geological conditions for geothermal energy-especially in the Jurassic rock formations around Neumarkt. The combination of BAFA subsidies (30-35%), low-interest KfW loans, and rising market value due to improved energy efficiency ratings makes geothermal projects in 2026 more economically attractive than ever. Those planning such projects should check the water protection zone status early on and initiate the approval process with the Neumarkt District Office in a timely manner-experience shows that waiting times have risen to 6-10 weeks in the spring of 2026.
Before starting the project, it’s worth taking a look at the current market value of your property: The valuation tool from leadmarkt.ch takes energy efficiency features into account and provides a data-driven estimate of how the geothermal investment will impact market value.
The permit process for geothermal drilling in Neumarkt i.d.OPf. is governed by the Water Resources Act (WHG), the Bavarian Water Act (BayWG), and the Bavarian Geothermal Guidelines (BayEWL 2019). The application is submitted to the Neumarkt District Office - Water Law Division.
Checklist for Permit Application in the Neumarkt District:
Processing times at the Neumarkt District Office were 6-10 weeks in the spring of 2026. Since drilling companies in the region are often fully booked with 12-16 weeks’ notice, a planning phase of at least 6 months prior to the desired installation date is recommended.
An analysis by the Neumarkt Expert Committee for the 2025 reporting year shows that geothermal heat pump systems increase the market value of single-family homes in Neumarkt by 4-8 percent compared to comparable buildings with gas heating-provided the system is less than 10 years old and achieves energy efficiency class D or better. For prospective buyers in Neumarkt, the question of the heating system is now one of the first questions asked during a viewing. A building that can demonstrate low operating costs (with an annual heating cost statement available) can be sold more quickly and at higher prices than a property of identical construction equipped with an old oil burner.
Compiled by the my-home.de editorial team in collaboration with regional real estate analysts. Data as of Q2 2026.
The Neumarkt region is located in the Franconian Jura, an area with moderate heat flow values. The LfU Geothermal Atlas of Bavaria indicates usable ground temperatures of 10-13 °C at a depth of 100 meters in the Neumarkt area, making geothermal probe systems economically viable.
For a well-insulated single-family home (150 m² of living space, 8 kW heating load), a borehole depth of 80-120 m per probe is typically required in Franconia. In the rocky regions of the Franconian Jura, the specific heat extraction capacity may be higher than in sedimentary rock.
The total cost of drilling, the geothermal probe, the heat pump, and integration into the heating system will range from €20,000 to €40,000 for a single-family home in 2026. The BAFA-BEG-EM subsidy and the KfW 261 loan can significantly reduce the out-of-pocket expense.
Yes. Through the BAFA federal subsidy program for energy-efficient buildings (BEG EM), heat pump systems are subsidized at a rate of 30-40% of the eligible investment costs. In addition, low-interest KfW loans are available (Programs 261 and 270). The income bonus for households with a taxable income of less than €40,000 amounts to an additional 30%.
In Zone I and II water protection areas, geothermal drilling is strictly prohibited. In Zone III, requirements under the Bavarian Water Act and the Bavarian Geothermal Atlas apply. A preliminary inquiry with the Neumarkt District Office is mandatory prior to any planning.
