The new models feature a redesigned heat exchanger, upgrading from your dual-surface to a more successful triple-surface construction to optimise along with improve thermal transfer. A new curved bell-mouth design is said to improve aerodynamics and cut down noise levels. The system works by way of recovering waste heat from in house units in cooling operation, and connecting to some purpose-built hot water cylinder, turning it into an ideal energy-saving solution intended for hotels and apartment blocks where hot water is in high demand. For example, the ECOi MF3 is said to provide 100% cooling potential at an ambient temperature of 43°C and still cool, even when the outdoors temperature reaches a maximum with 52°C. 4kW model).Boasting a superior SEER/SCOP at full load capacity plus an increase in piping length and may be connectable indoor units, the ECOi-EX MF3 sometimes appears as a major improvement in its MF2 series. A slim heat recuperation box, measuring only 200mm huge, makes it easier to install in elements of limited ceiling space. To further increase set up options, the ECOi MF3 offers an increase in how many indoor connectable units compared that will previous models
