OCHSNER heat pumps are SmartGrid ready. With the highly developed, user-friendly control technology, you can already increase the self-consumption of your photovoltaic system today. In addition, photovoltaics and green electricity enable climate-neutral operation. As soon as the planned, intelligently controlled power grids are implemented, you will benefit from low-cost renewable electricity from so-called "SmartGrids".
Heat pumps
Comfortable warmth in winter, hot water for the bathroom and kitchen, pleasant room temperatures on hot summer days: a heat pump can combine all these requirements in a single technology. No direct CO2 emissions are generated at the installation or operating location. Heat pumps are an important key technology in the fight against climate change. A heat pump is one of the few heating technologies that generates heat without the finite fossil fuels oil or gas and without biomass. It is also the only type of heating that can optionally provide air conditioning and cooling. Thanks to their high efficiency, OCHSNER heat pumps are suitable for use with underfloor heating systems in new buildings and renovations, as well as for supplying radiators when replacing a heating system.
Advantages of a heat pump
Purchasing and installing a heat pump heating system offers a range of advantages
Future-proof
Generate heat With a heat pump, you get a future-proof heating system and reduce your CO2 emissions.
Heat independently
The heat pump makes you independent of fluctuating oil and gas prices and supply bottlenecks for fossil fuels. It uses only environmental heat and electricity.
Improve sustainability
Heat pumps use electricity highly efficiently. If the electricity is generated from renewable sources such as solar and wind power, they are particularly sustainable.
Save heating costs
Energy from the ambient air, water or ground is available free of charge. Only the electricity used to drive the heat pump process is added to the heating bill. If a photovoltaic system on the roof generates part of the electrical energy, electricity costs fall further.
Increase comfort
Electronic heating controls offer maximum ease of use for controlling and operating a heat pump. As a central heating system, it can be optimally adjusted to the needs of the occupants and provide tailored space heating, hot water and room cooling.
Low maintenance costs
The maintenance required for a heat pump is comparatively low. Chimney maintenance and cleaning are completely eliminated. With internet-enabled control technology, inspections can optionally also be carried out online and without travel costs.
Use subsidies to finance the system
The switch to a heat pump is strongly subsidised because of its major importance for climate protection. Go to the subsidy database.
Enjoy flexibility
Heat pumps can also be used as hybrid systems in combination with other heat generators, such as solar thermal systems or biomass. This allows solutions to be tailored perfectly to your building.

How does a heat pump work?
A closer look at the technology behind the heat pump shows that, unlike gas, oil or wood heating systems, heat pumps generate heat without combustion. They transfer thermal energy from a source such as air, ground or groundwater to another system, usually heating or domestic water. A thermodynamic process raises the temperature level. A refrigerant with a very low boiling point is essential for this process; it evaporates, is compressed and liquefied in a multi-stage sequence:
1. Evaporator
In an evaporator, which extracts heat from the air, ground or groundwater, the refrigerant is made to evaporate. Under low pressure, it changes its state from liquid to gas and absorbs heat from the source.
2. Compressor
The gaseous vapour is then compressed under high pressure in a compressor. This increases its temperature. The higher the pressure, the greater the increase and the electricity required to drive the compressor. The technical intelligence of an OCHSNER heat pump lies, among other things, in the optimum ratio between the temperature increase achieved and the electricity consumption.
3. Condenser
The refrigerant vapour, which is under high pressure and at a high temperature, is liquefied in a condenser designed as a heat exchanger. At this point, the generated heat is transferred to the heating or hot water system and the refrigerant cools accordingly.
4. Expansion valve
The refrigerant then flows through an expansion valve, cools down significantly again as it expands and reaches the same temperature and pressure level as at the beginning of the process. It can now absorb heat again and the heat pump process starts over.
What types of heat pumps are available?
OCHSNER offers you a choice of heat pumps for different heat sources. The choice of the right model depends on which sources are available at your property. Air can almost always be used as a heat source, while certain conditions must be met for ground or water.
Air heat pumps
The air-to-water heat pump uses energy from the ambient air. For good reason, the air heat pump is the most widely used heat pump system in building heating. Air is available everywhere in unlimited quantities. No additional development work is required. OCHSNER air heat pumps can therefore be installed almost anywhere with comparatively little effort.
Ground-source heat pumps
As this energy source provides very consistent temperatures throughout the year, ground-source heat pumps from OCHSNER consistently achieve very good efficiency values. To use geothermal energy, the property must be sufficiently large; deep drilling generally requires permits.
Groundwater heat pumps
The constant year-round temperatures between 8 and 12 °C make groundwater a heat source that can be used with particularly high efficiency via water-to-water heat pumps. A prerequisite is that groundwater can be found at an accessible depth near your home and that its use is approved by the responsible authorities.
Hot water heat pumps
The hot water heat pump, also known as a domestic hot water heat pump, uses heat obtained from room air, for example from basements, storage rooms or ancillary rooms, to prepare hot water. OCHSNER offers the widest range of heat pump solutions for hot water preparation only – independently of the conventional heating system. Thanks to the relatively consistent source temperatures, OCHSNER hot water heat pumps operate highly efficiently and reliably deliver water temperatures of up to 65 °C.
Heating with a heat pump
The heat pump uses energy sources that are available in virtually unlimited quantities: stored solar heat from the ambient air, groundwater, the ground or other existing heat sources. It converts low-temperature heat into high-temperature heat, even in winter when temperatures are well below zero. Around three quarters of the energy are extracted from the environment in a climate-neutral and free-of-charge way; only one quarter comes from the power socket. How efficiently a heat pump operates depends on the heat source and, crucially, on the technology.
Preparing hot water with a heat pump
The heat pump can also be used to heat drinking water. Hot domestic water can be provided using various storage technologies, either with separate storage tanks or in combination with a heating buffer storage tank. Separate hot water preparation via heat pump boilers is also possible. OCHSNER offers the world's largest range of hot water heat pumps, which also use waste heat, among other sources. With separate drinking water heating, the heating system can be switched off completely in summer. This improves efficiency and protects the technology.
Cooling with a heat pump
Heat pumps can also be used for cooling and air conditioning. Depending on the heat source and the design of the technology, they cool in two ways: passively or actively. Passive cooling works with the ground and groundwater heat sources. Heat is removed from the house and released into the ground or groundwater, which is significantly cooler. The room temperature can be reduced by around three degrees. Active cooling requires somewhat more energy and is more effective. It works like an air-conditioning system and is possible with air as the heat source. The heat pump process is reversed, allowing greater cooling.
When does a heat pump make sense?
Highly efficient OCHSNER heat pumps can be used in new buildings as well as for modernisation and the subsequent integration of renewable energies in the home.
Heat pump for new buildings
Newly constructed buildings with good insulation and a correspondingly low heating load are ideally prepared for heat pumps. Underfloor heating systems are standard in new buildings today. All heat sources are suitable for new buildings provided the relevant conditions are met.
Retrofitting heat pumps in older buildings
Heat pumps are now also commonly used in renovations and modernisations of older single-family and multi-family homes. OCHSNER offers powerful heat pumps that provide high flow temperatures of up to 70 degrees and can therefore also be operated with radiators. The air heat pump is particularly easy to install during renovations and refurbishments because it requires no additional development work. In an established garden, installing flat-plate collectors is difficult because the ground must be excavated. Deep drilling or groundwater are possible alternatives if the geological conditions are suitable. In older buildings, hybrid systems can also be a sensible solution, for example a combination of a heat pump with biomass or a heat pump plus solar thermal energy. Find out more here about the use of heat pumps in renovations and modernisations.
How much does a heat pump cost?
Would you like to estimate the investment costs you can expect for a heat pump and how high the heating costs are likely to be? Use the OCHSNER product configurator. It provides you with several model suggestions that match your property, planned house or requirements. In principle, investment costs vary depending on the heat source selected. Air heat pumps are comparatively inexpensive to purchase. For ground-source or groundwater heat pumps, the costs of excavation or drilling work and permit procedures must be added. The even higher efficiency of these solutions can pay off in the long term through lower energy costs. The insulation standard of the house also influences the actual heating costs. In any case, with a perfectly planned and designed heat pump, you benefit from it operating more energy-efficiently than all other heating systems and extracting most of its energy from the environment free of charge. Your OCHSNER system partner will be happy to provide you with a quote for a system that fits your home perfectly.
Electricity consumption of a heat pump
A persistent misconception about heat pumps is that they consume a great deal of electricity. This is not true, as a correctly sized and highly efficient OCHSNER heat pump obtains three quarters of its heat energy from the environment, with only around one quarter supplied as electrical energy. All OCHSNER heat pumps meet the requirements for energy efficiency classes A+++ to A+ and thus ensure low electricity consumption. In our heating cost calculator you can get an overview of the expected electricity costs.
Subsidies for heat pumps
The use of environmentally friendly heat pump technology is subsidised. Depending on the country and region, homeowners and builders can use various subsidy programmes. You can find out here which subsidies may be available to you and what needs to be considered. With OCHSNER heat pumps, you can be sure that the requirements and efficiency criteria of all relevant subsidy programmes are met.

Heat pump & photovoltaics
Combining a heat pump with an in-house photovoltaic system makes it almost completely climate-neutral. It uses a large proportion of the electricity generated on site. Increasing self-consumption also makes the PV system more economical to operate. All OCHSNER heat pumps are Smart-Grid-ready and therefore already prepared for the use of solar electricity. The following advantages support combining a heat pump with a photovoltaic system:
Green electricity
The photovoltaic system produces climate-neutral green electricity and makes operating the heat pump even more sustainable.
Operating costs
Combining a heat pump with a PV system noticeably reduces operating costs.
Independence
Heating costs become less dependent on the electricity prices charged by grid operators.
Noise level of an air heat pump
Air heat pumps require a fan, which is generally installed outside the house. Loud fan noises can disturb residents and neighbours. Thanks to the highly developed fan technologies of OCHSNER horizontal split evaporators, the outdoor noise of OCHSNER heat pumps is extremely low; special Silent Modes ensure a further reduction in sound emissions. Since ground-source or groundwater heat pumps do not have an outdoor fan unit, noise emissions play hardly any role here.
Top scores in sound tests
OCHSNER air heat pumps regularly achieve top scores in sound tests.
Minimal noise
The indoor components of OCHSNER air heat pumps generate only minimal noise, allowing them to be installed in hallways or utility rooms.
