Function of an Air Heat Pump Heating System
The operation of all air heat pumps is the same: A fan draws in outside air, which evaporates the refrigerant in the heat pump through heat exchangers. The heat pump cycle compresses it in an electrically powered compressor to a higher temperature level. Through heat exchangers, the energy is transferred to water, making it usable for heating and providing hot water.
The differences in detail are essential: The highly efficient OCHSNER technology makes it possible for even cold outside air temperatures to still provide enough energy for heating and hot water. For this, refrigerants with very low boiling points are used. Above all, all components must be optimally coordinated and work perfectly together. Thus, you can rely on the highest efficiency with minimal electricity consumption from an OCHSNER air heat pump. Simpler entry-level devices work with vertical fans to draw in air. In its high-end systems, OCHSNER relies on table evaporators with very high-quality horizontally installed fans. They offer you higher performance and operate more quietly.
To stay technologically at the forefront, OCHSNER heat pumps invest around 6 percent of their sales in research and development each year.

Why OCHSNER Air Heat Pumps
are particularly quiet
That fans create noise when drawing in air is not entirely avoidable. Inexpensive systems can be very loud, leading to issues with your neighbors or disturbances to your own sleep. Regional regulations on noise protection must also be observed.
Table Evaporators
The OCHSNER table evaporators with horizontally installed fans regularly achieve top scores in noise development in independent tests: They run extremely quietly.
Whisper Management
With OCHSNER's premium air heat pumps, you also benefit from inverter technology. It continuously adjusts both the compressor's output and the fan speed to the current heat demand. This makes operation significantly more efficient and quieter. With a special silent mode, the output can be further reduced at certain times. Additionally, there are soundproofing covers for the outdoor units.
For High Noise Protection Requirements
OCHSNER air heat pumps therefore offer solutions for almost any construction situation in densely built residential areas with high noise protection requirements. Your OCHSNER system partner will advise you on your project.
Advantages of an OCHSNER Air/Water Heat Pump
For the installation of an OCHSNER air-water heat pump, neither drilling nor the laying of collectors is required. The installation is therefore faster and easier than with systems using ground or groundwater as heat sources. The space-saving indoor units are hardly larger than a refrigerator and can be easily placed in your basement, utility room, or hallway areas. The outdoor units can be placed in the garden or on garage and flat roofs. Prepared connections make it easy to connect to your existing heating and hot water installations. For commissioning, service, and maintenance, the comprehensive OCHSNER customer service is available to you.
Choosing the Right Air Heat Pump
At OCHSNER, you will find air heat pumps for various types of buildings and heating loads – from single-family homes to multi-family houses. The heat generated can be distributed in the building via underfloor heating or through radiators/convectors, depending on the model. Additionally, all devices are SG Ready and suitable for combination with photovoltaic systems. Since the selection of the optimal heat pump depends on numerous factors, we recommend comprehensive advice before purchase. In addition to heating or cooling needs, spatial conditions should also be considered – especially in the case of an old building.
The Most Frequently Asked Questions about Air Heat Pumps
Heat pumps draw a large part of their energy from the environment: air heat pumps from the surrounding air. However, energy solely from the environment is not sufficient for the operation of the heat pump. In general, the electricity consumption of air heat pumps is somewhat higher than that of ground source heat pumps and water heat pumps. You can find out exactly how high it is using our heating cost calculator.
OCHSNER air heat pumps can deliver flow temperatures of 60 °C or 65 °C in pure heat pump operation, depending on the model. This generally provides sufficiently high temperatures for heating with classic radiators. OCHSNER has thousands of positive references. To ensure that the house, heating system, and air heat pump fit together optimally, a precise calculation by an OCHSNER system partner is important.
OCHSNER air heat pumps are very low maintenance. Chimney sweeps and exhaust gas inspections are not required; only a regular check of the refrigerant circuit for leaks is necessary. An annual inspection of the entire system is recommended.
At temperatures between -7 °C and +7 °C and high humidity, icing can occur on the evaporator heat exchangers due to condensation of moisture. For table evaporators, OCHSNER therefore uses the so-called hot gas defrosting through refrigerant circuit reversal. Essentially, hot gaseous refrigerant from the compressor is briefly redirected back into the evaporator. The ice melts, and full performance is restored.
In general, the air heat pump can be combined with a solar system, but the interaction with a solar thermal system for hot water is not the best choice, as a higher additional investment for hot water preparation is met with lower annual efficiency with the heat pump. However, coupling with a photovoltaic system that provides electricity for the air heat pump is very sensible. All OCHSNER air heat pumps are Smart Grid-Ready, meaning they are prepared for the use of self-generated electricity or favorable tariff times.
In general, the air heat pump is the most affordable option among heat pumps for heating and hot water. The price consists of the costs for acquisition, installation, and operating costs. For air heat pumps, in addition to low maintenance costs, electricity consumption primarily determines the annual operating costs. Our OCHSNER heating cost calculator provides precise information on the costs of an air heat pump.
OCHSNER air heat pumps from the series OCHSNER AIR and OCHSNER AIR HAWK are among the quietest heat pumps on the market. In this context, they achieve record values in independent testing institutes. Therefore, they are excellent for use in densely populated areas.
For even quieter operation, the models from the AIR and AIR HAWK series feature an integrated Silent Mode. An optional Super Silent Mode is available for all types in the AIR series. The extremely low sound emission is further reduced through special design optimizations.
Additional noise-reducing measures, including the use of soundproof covers or dense planting, are generally not necessary.
Yes, in addition to being used for heating, heat pumps can also be used for cooling. Simply put, their functionality is reversed. The heat is not released into the room but absorbed and directed outside. In active cooling, for example, cold water circulates in the underfloor heating instead of warm water.
The advantage is that there are no additional costs for a separate air conditioning system, and your home maintains pleasant temperatures year-round. All OCHSNER air heat pumps can also be optionally designed for air conditioning. We would be happy to advise you on this – we look forward to your contact!
Both types differ in their functionality and in the distribution of the generated heat. In the former, air is heated and released into the rooms via a air distribution system. In the latter, water plays a crucial role. This is heated and distributed inside the building via radiators or underfloor heating. OCHSNER air heat pumps are always air/water heat pumps.
