Electric heat pumps are a professional solution for heating and cooling large buildings such as industrial facilities, schools, sports facilities, offices and hotels. Depending on the requirements, professional multi-split systems or VRF systems can be used.
Several VRF outdoor units can be combined for a total output of up to 224 kW. Even at very low outdoor temperatures of -25 °C, the electric heat pumps can achieve up to 70 % of the nominal heating output. The electric heat pumps are therefore ideal for universal use as the main heating system. In cooling mode, the heat pump provides 100 % of the nominal cooling capacity up to an outdoor temperature of +43 °C. These new heat pump systems from Panasonic are characterised by outstanding energy efficiencies, delivering the highest ESEER values (European Seasonal Energy Efficiency Ratio) and working extremely efficiently even in partial load operation.
By exclusively using inverter-controlled high-performance compressors, these systems can significantly reduce energy costs. The optimised design of the enlarged three-layer heat exchanger significantly increases its heat transfer capacity. The newly designed discharge opening achieves an improved airflow of these electric heat pumps. The possibility of a maximum total pipe length of 1,000 m, the wide range of indoor units, the large selection of control and regulating devices as well as peripheral equipment provide the necessary flexibility for the optimum climate in each application.

Two Different Electric Heat Pumps for Heating and Cooling
VRF System: for Simple to Complex Applications
The electric heat pumps of the ECOi series are an ideal solution for the highly efficient heating and cooling of more complex buildings with several rooms or zones, such as hotels, office facilities and commercial buildings. Thanks to the variable refrigerant flow (VRF), the required output of up to 224 kW can be distributed individually inside the building, even over longer distances and up to 64 indoor units. Heating is possible at outside temperatures of down to -25 °C and cooling up to +52 °C. In cooling mode, 100 % of the nominal cooling capacity is still available at temperatures of up to +43 °C. The units achieve extremely high efficiency values SEER (Seasonal Energy Efficiency Ratio) up to 7.6 and SCOP (Seasonal Coefficient of Performance) up to 4.9.
Single-split Heat Pumps: Efficiency Coupled with Simplicity
The PACi air-to-air heat pumps with a nominal output of up to 25 kW are extremely compact and very suitable for less complex buildings, such as industrial buildings. By using several single-split units in parallel, even large building sections can be efficiently heated and cooled, all electrically. Cooling operation with the electric heat pumps is possible at outside temperatures up to +48 °C and heating operation down to -20 °C. The environmentally friendly refrigerant R32 is used.
Advantages of Schwank Electric Heat Pumps
The Electric Heat Pump Has Unparalleled Energy Efficiency in High-Performance Operation
The most important benefits of electric heat pumps:
- highest energy efficiency due to inverter-controlled double-roller piston compressor
- maximum flexibility due to max. total pipe length of 1,000 m
- wide range of different connectable indoor units
- can be combined with water heat exchangers for hot/cold water applications

Industry and Logistics Buildings: CO₂-neutral heating thanks to Solar Air Collectors
A brandnew topic for industry and logistics are the constantly rising energy costs for gas and electricity and the trend towards decarbonisation. If a reduction of CO₂ emissions and energy use is the objective, you can think and act responsibly.
Breakthrough: Climate-neutral Heating with Hydrogen Operated Schwank Tube Heaters
For years, the manufacturers of infrared heaters have been advertising the modernity and future viability of their technology. Now the industry, and above all the Schwank company, has set a groundbreaking milestone with the development of its first 100% hydrogen-compatible tube heating system.
Energy Efficiency is Vital for Reaching Net Zero
A post on the EURACTIV website has included a statement by Paula Pinho from the European Commission’s Energy Directorate, which read as follows: “We believe that, first and foremost, we need to continue to apply the energy efficiency first principle, ensuring that really we make the most out of our limited resources.”
