The Estía Powerful of air-to-water heat pumps for heating consists of 5 models, 2 single-phase and 3 three-phase, to suit any residential or small office application.
The outdoor units are equipped with the Toshiba DC Twin Rotary Eco-driving compressor, which guarantees maximum efficiency for the entire system.
With the help of the HWS-AMS54E-EN controller, up to 8 heat pumps can be operated in parallel in the same application. The electric heater at the base of the outdoor unit prevents ice from forming on the outdoor unit's heat exchanger. Compared to the Estia Standard, Estia Powerful is able to guarantee heat output even at very low outdoor temperatures, thanks to the increase in the number of circuits in the heat exchanger. Estía Powerful maintains 100% of the nominal capacity up to -15°C outside temperature, moreover, operation is guaranteed at outside temperatures down to -25°C, making it a unique and versatile product for all primary heating requirements, even the most extreme, without having to provide any backup or support device.
The hydronic modules are all equipped with a 6-speed pump in energy class A.
The system can also be combined with a domestic hot water tank available in three sizes of 150, 210 or 300 litres, which can be selected according to the intended use. The hydronic module is equipped with a control on board the machine that can manage two different temperature zones, not only in different rooms, but also with different types of terminals.
