Correct sizing of the system is paramount to trouble-free operation and the lowest heating bills. Our professionally trained system partners can help you to plan your heat pump heating system, whether for a new build or refurbishment project.
The individual circumstances are analysed in detail and your wishes are taken into account in order to determine which type of heat pump is perfect for you.
Engineering information for your new build
Additional and unnecessary costs can easily be avoided by including a heat pump in the plans for your new build from the outset. By speaking with an OCHSNER system partner at an early stage, you will see just how straightforward it can be to get the perfect heat pump system designed, selected and installed.
Installing a heat pump in a new building increases building efficiency (energy performance certificate) and adds value to the system technology.
Effective use of surface heating systems
The larger the heating surface area for dissipating heat inside a room, the higher the ratio of radiant heat, the more even the dissipation of heat and the more comfortable we feel.
At a room temperature of just 20°C with underfloor or wall heating, we perceive the same degree of well-being as in a conventionally heated room at 22°C. This is not only pleasant and healthy, but also saves a huge amount on heating costs. Additional low temperature radiators are recommended for cooling with a heat pump.
Engineering information for heating system refurbishment
Air as a heat source is often ideal for heating system refurbishment. Unlike with water and brine, no labour-intensive tapping of the heat source (earthwork, drilling, digging, etc.) is necessary. It is possible in principle to combine a heat pump with existing radiators and effectively operate such a system.
Depending on the situation, you can either completely replace, or supplement, your existing boiler with a heat pump. In both cases, the savings are substantial. If you retain the existing boiler, this is then used only on the coldest days and works efficiently together, in symbiosis, with the heat pump.
Retrofitting with state-of-the-art OCHSNER air source heat pumps
OCHSNER was the first manufacturer to launch a complete range of heat pumps with flow temperatures of up to 65°C.
Bearing in mind that it is often impossible to use ground or water as a heat source when retrofitting a heat pump, OCHSNER has developed a range of products with air as the heat source, especially for heating system refurbishment. Thanks to new technology and a large evaporator (enabling efficient absorption of environmental energy even when outdoor temperatures are at their lowest), high coefficients of performance are achieved with outdoor air as well.
New benchmarks and world records have been set, as confirmed by external tests carried out at the Buchs heat pump test centre in Switzerland. Our system partners are happy to advise and support you in planning your heating system modernisation. Please feel free to contact us.
Engineering information for DHW heating
OCHSNER hot water heat pumps in the EUROPA series use air/exhaust air as the heat source. They achieve a DHW temperature of up to 65°C as standard in heat pump-only mode (Europa Mini up to 60°C).
Multifunctional appliances can be sited in any room Thanks to silent operation without generation of odours or soot.
The OCHSNER Europa Mini can be installed without any major effort and connected to a tank. This small and very affordable hot water heat pump can also be used as a split appliance anywhere.
The integral charging pump and plate heat exchanger ensure the required "charging" of the domestic hot water in the tank.

Benefits of DHW heating with an OCHSNER heat pump
There are good reasons to heat domestic hot water for your home with a multifunctional appliance like an OCHSNER hot water heat pump. Installation in new build is a straightforward process. In the case of most existing buildings, a hot water heat pump can be retrofitted even if you already have a DHW tank installed that would normally be heated by a boiler.
Due to the efficient centrifugal fan and the aerodynamically optimised volute casing, air ducts of more than 10 m in length can be connected to OCHSNER's EUROPA multifunctional appliances. This allows for a whole range of additional benefits:
- Cooling effect: transform your pantry into an oasis of freshness in summer or use the effect to keep your wine at a cool temperature.
- Dehumidification of basements and utility rooms: dehumidified utility rooms and basements have the advantage when it comes to getting laundry dry. This makes light and fast work of domestic chores.
DHW heating with OCHSNER multifunctional appliances also results in lower running costs. Compared with solar thermal systems as well as oil, gas and pellet central heating systems, using a heat pump with DHW tank reduces your costs and energy consumption. Approximately 75 % of the energy required to heat the domestic hot water is drawn from the environment, while only about one quarter is supplied by electricity.
You can further reduce your outlay through combination with a photovoltaic system. What's more, you can often take advantage of attractive subsidies – whether refurbishing your heating system or installing a heat pump in a new build.
More than just DHW heating
EUROPA multifunctional appliances can also dry, cool and provide proper ventilation.
Example A
Type Europa 250 DK, 333 GENIUS, 300 L and Mini IWP/IWPL
- Installation in a boiler room
- Domestic hot water heating using indoor air
- Ancillary benefits, cooling of larder or wine cellar
Example B
Type Europa 250 DK/DKL, 333 GENIUS, 300 L and Mini IWP/IWPL
- Installation in a laundry room
- Domestic hot water heating using indoor air
- Additional benefits – laundry can be dried in the installation room; softened water for steam irons
Other areas of application for the OCHSNER Europa Mini
Example C
Type Europa 333 GENIUS / mechanical ventilation as extract air system
- Installation in a hobby room with a heating heat pump
- Heat recovery from extract air for DHW heating
- Ancillary benefits, mechanical ventilation (hygienic 1 pipe system, air duct DN 150 up to 20 m possible)
Extraction of the stale, moist air from wet rooms (bathroom, WC, kitchen). Intake of fresh air through adjustable wall vents into the living space and/or stairwell.
