Geothermal Heat Pumps
Groundwater Heat Pumps
Geothermal heat pumps – also known as groundwater heat pumps – draw on the heat stored in the ground, which is available for free. The geothermal heat pump is particularly powerful and offers convincing advantages for both owners and the environment. Typically, it is sufficient to penetrate just a few meters into the ground to obtain temperatures that can be converted into heating heat using the heat pump. Those who choose a geothermal heat pump can also benefit from various subsidies – this greatly facilitates the transition to geothermal energy and geothermal heating.
Geothermal energy for your Home
OCHSNER geothermal heat pumps have been a proven solution for decades to utilize the heat of the ground for an environmentally friendly and efficient supply of buildings. Since this energy source experiences only minor temperature fluctuations throughout the year, OCHSNER's geothermal heat pumps consistently achieve very good efficiency values. In environmentally friendly heating with geothermal energy, fossil fuels are avoided, and CO2 emissions are reduced.

Function of a Geothermal Heat Pump
Geothermal heat pumps utilize the consistent temperature level of the ground as a constant and reliable energy source. This type of heat pump heating extracts heat using a system of three circuits. Brine Circuit: Here, heat is extracted from the ground. Refrigerant Circuit: As the main component of the actual heat pump, it converts the energy from the ground into heating heat and hot water. Heating Circuit: Distributes the extracted heat evenly in the living space. The heat is absorbed in the ground and raised to a higher temperature level through the thermodynamic heat pump process. This energy is available for the heating system and hot water preparation. When extracting geothermal heat using flat collectors, it must be noted that these are subject to reporting requirements. This requires less space.
With the Geothermal Heat Pump Reduce Costs &
Electricity Consumption
Even if the costs for purchasing a geothermal heat pump may seem quite high at first glance, they pay off through future savings after just a few years. You can also reduce electricity costs with a geothermal heat pump – for example, by combining it with a photovoltaic system.
The OCHSNER product configurator will tell you exactly what costs you need to expect for the installation and operation of a geothermal heat pump.
Cooling with Geothermal Energy
Your OCHSNER geothermal heat pump can be designed so that geothermal energy can also be used for cooling and tempering in summer. Passive cooling removes heat from underfloor heating through ground probes to the ground. Since the ground is cooler than the air in the house at constant temperatures around 10 °C in summer, room temperatures can be lowered by a few degrees. The energy costs are minimal, as only the circulation pump for the heat medium in the ground probes is activated.
Efficient Heat Storage in the Cold Season
The tempering through the OCHSNER geothermal heat pump utilizes the ground as a heat storage. The waste heat from the house can therefore improve the heat yield in the cold season.
The Most Frequently Asked Questions about Geothermal Heat Pumps
A cooling of the garden with visible traces on the vegetation can only occur if the collector area is designed too small. In the professional planning and design, the OCHSNER system partner will take soil samples in addition to the key data or rely on experience values in the region. It is advisable to plan reserves for a possible increase in the number of people or a later extension when designing the collector area.
The installation of the ground collectors is always deep enough in the ground in the frost-free area with proper planning. Freezing is therefore excluded.
For the retrofitting of heat pumps in old buildings all types of heat pumps are generally suitable – including the powerful ground source heat pump. However, the basis for retrofitting consists of ground heat probes or ground collectors. Their subsequent installation is not possible in all old buildings. Especially in densely built areas, subsequent development becomes more difficult. The cost of retrofitting a heat pump depends on various factors.
How expensive a heat pump is and how quickly you can save money again through the favorable operation depends mainly on the electricity consumption. The electricity consumption of a ground source heat pump, in turn, is based on the performance of the heat pump, which you can calculate in advance with our configurator .
The OCHSNER ground source systems are almost maintenance-free. Flat collectors and ground probes are very durable and robust, and they usually do not require maintenance or repair work. An inspection of the entire system once a year is recommended.
The costs for ground heat drilling can – depending on the respective project – vary greatly. The largest cost factor is the desired drilling depth. This depends, among other things, on the nature of the soil at the chosen location.
Surface collectors are generally subject to notification and ground probes over 100 m deep are always subject to approval by the lower water authority and must be approved by the geological state office.
