OCHSNER ground source heat pumps
Geothermal energy for your home
For decades, OCHSNER ground source heat pumps have been a tried and tested solution for efficiently supplying buildings with environmentally friendly heat from the ground. Since this energy source is subject to only minimal temperature fluctuations throughout the year, OCHSNER ground source heat pumps achieve very good efficiency values, continuously and reliably.
Product overview



The OCHSNER recipe for success!
Making the best use of geothermal energy
Ground source heat pumps use the even temperature of the ground as a constant and reliable source of energy. This energy can be tapped in two ways, depending on the conditions on site: via collectors laid horizontally in the ground, or geothermal probes sunk vertically. In both cases, heat is drawn from the ground and the temperature level raised by means of the thermodynamic heat pump process. This energy is then available for the heating system and for DHW heating.

Free geothermal energy
The thermodynamic heat pump process makes use of free geothermal energy for heating and DHW heating.

Temperature control with an OCHSNER ground source heat pump: cooling and thermal store charging
Your OCHSNER ground source heat pump can be designed to additionally allow cooling and temperature control in the summer. In passive cooling, heat is transferred from surface heating systems to the ground via geothermal probes. Since the ground is cooler than the air in the house in summer, with temperatures constantly in the region of 10°C, room temperatures can be lowered by a few degrees. The energy costs are minimal, because only the circulation pump for the heat transfer medium in the geothermal probes is activated.

Heat yield in winter
OCHSNER heat pumps provide temperature control by using the ground as a heat store. This makes it possible to use waste heat from the house to improve the heat yield in winter.
Five questions about ground source heat pumps
Cooling of the garden with visible signs on the plants can only happen if the collector area is an insufficient size. As well as the key data, OCHSNER system partners take soil samples or use empirical values from the region as part of their professional planning and sizing. It is advisable to include some surplus collector area to allow for any increase in the number of people or a subsequent extension.
With the right planning, the geothermal collectors are always laid deep enough in the ground in a frost-free location. This rules out any freezing.

OCHSNER ground source systems are almost maintenance-free. Horizontal collectors and geothermal probes are very durable and robust and do not normally require any maintenance or servicing. An annual inspection of the whole system is recommended.

Notification is required for horizontal collectors and all geothermal probes over 100 m deep are subject to approval by the local water authority and the State Office for Geology [Germany].

Natural, warm materials. Surface designs for indoor units
The silk matt and satin finish with the distinctive red stripe design gives the indoor unit of your Ochsner heat pump a pleasant look and feel. The integration of natural, warm materials into the top of your heat pump transforms it from a purely technical product into an attractive indoor fitting. You can choose from 6 designs.

- Sample cards are available for the surface designs. For further information, contact your OCHSNER sales partner.
- Due to the printing process, the surfaces depicted here may differ from the original surface finishes.
Attractive subsidies for heat pumps
Many different regional grants or indirect subsidies are available through housing construction and renovation schemes. Some energy providers offer financial support or special electricity tariffs.
