The Panasonic Aquarea K-series heat pumps, with capacities ranging from 3 to 9 kW, are designed for both new construction and renovations. They use the environmentally friendly R32 refrigerant, ensuring high energy efficiency and low CO2 emissions. The compact indoor units simplify the installation process. The series is robust, operates reliably in various weather conditions, and supports the Aquarea Smart Cloud for easy remote management, making it ideal for installers.

Don't forget to order the indoor unit and necessary components
This outdoor unit requires an indoor unit. Refer to the 'Related' section to select a matching indoor unit. If you combine this outdoor unit with an All-in-One indoor unit, it is the KIT-ADC03K3E5. In combination with a Bi-Bloc indoor unit, it becomes the KIT-WC03K3E5. To remotely access the heat pump, we recommend ordering the Smart Cloud adapter, which can also be found under the 'Related' tab.
