Installation options
You can order the AWA32 heat pump system as a SPLIT set, where the hydrobox is placed above the ZETA TC air heater and forms one unit, or as 3 separate components with the possibility of placing the hydrobox on the ground or on a pillar under the ZETA TC air heater.
The exterior unit of the heat pump can either be placed on the side of the hall on a separate console or on a sufficiently high plinth in order to allow condensate to drain.

A+++ energy level
With the highest A+++ energy class, the unit is the most energy-efficient and can significantly reduce energy costs for customers. However, in order to keep the dT of the heated air as low as possible, it is necessary to operate the system with the lowest possible temperature drop and the highest air flow. The system can also be operated at a very comfortable dT of 20°C, with the necessity of accounting for a reduction in COP efficiency, as shown in the following graph.

Fast defrosting
The heat pump makes use of smart defrosting by way of frequency control and EEV technology. Thanks to the use of a buffer tank hidden in the Hydrobox, cold air does not leave the ZETA TC air heater, because the exterior unit takes its defrosting energy from the buffer tank and not from the hall.

EVI + DC inverter technology
With this technology, the heat pump can optimally control the frequency and EEV according to the surrounding temperature and return water temperature and refrigerant volume of the main refrigerant circuit, even if the ambient temperature drops below -15°C. A heat pump can provide a very decent heating performance even without any auxiliary electric heater.
