From development to the finished product
DEVELOPMENT
Energy awareness and pioneering spirit shape the development of our systems. The heat pumps are further developed and optimized in close cooperation with the FH Burgenland. They are tested in our in-house heat pump test center to guarantee trouble-free operation and high performance.
PRODUCTION
Starting with heating and cooling as well as for domestic hot water preparation, we offer you a complete product range of heat pumps for single and multi-family houses, office buildings and smaller industrial buildings. With system temperatures up to 60°C, the HERZ heat pumps can also be used for renovation.
AWARDS
HERZ heat pump systems correspond to the highest requirements and are also awarded with the EHPA quality seal. Our product range is constantly being further developed and confirmed by renowned testing institutes with certificates. Thanks to our innovation strength, we already have received some awards with our products.

How does the system heat pump work?
The refrigeration circle
A heat pump uses stored solar energy or ambient heat e.g. from the air, the ground or from the ground water. To use this heat for heating purposes, the heat pump uses a so called refrigerant. The refrigerant evaporates due to its low boiling point even at relatively “low” temperatures of the heat source. The evaporated refrigerant is compressed in the compressor. This increases the temperature to the required level. In the so-called condenser, the “hot” refrigerant is liquefied again. The heat energy is transferred to the heating system. At this point the cycle is closed and starts all over again.
