A RES split hybrid system for wall-hung solution, is a multi-energy hybrid system for heating, cooling, and the production of domestic hot water. This system consists of:





- the wall-hung mounted boiler: depending on the installation needs, the choice of the gas generator can be made by choosing between boilers from 25 to 35kW, heating only or combined, for wall-hung installation (indoors or outdoors in partially protected places) or from recessed. The boilers have a 1: 5 or 1: 8 modulation ratio, depending on the model and are all equipped with high efficiency circulators. The system control panel is able to activate the most energy-efficient heat source based on the climatic conditions, and to manage the system with up to 2 independent hot / cold temperature zones.


- the heat pump: split basement air-water type of the Domus ES series, available in versions ranging from 5 up to 15 kW, with basement indoor unit for heating, cooling and for the production of domestic hot water . The compact and silent outdoor unit includes a Twin Rotary DC inverter compressor, electronic expansion valve, fans with brushless motor and finned coil optimized for heat pump operation even with external air temperatures of -20 ° C. The main components of the hydronic system, on the other hand, are housed in the indoor unit, including a 200l inertial tank with large surface stainless steel coil for instantaneous production of domestic hot water.


- The hydraulic distribution module: the choice can be made between the simple Hbox hydraulic node, and the more flexible BAG³ Hybrid distribution module. Hbox allows you to make a simple hydraulic connection between the two generators, creating a one-way direct system in which the boiler and heat pump pumps are responsible for powering the system.


For more complex systems, the BAG³ Hybrid distribution module is available: for recessed or wall-mounted indoor installations, or recessed outdoor installations, in the 1 direct, 2 direct or 1 direct and 1 mixed configurations, equipped with self-modulating circulators low consumption (EEI≤0.20). The distribution module also acts as a hydraulic separator between the generators and the system circuits. The system is designed for connection to a single coil domestic hot water tank served by a heat pump, or to a double coil domestic hot water tank served by a heat pump and solar thermal, by installing the diverter valve kit.


- Simple and intuitive control panel with large backlit display, characterized by advanced management logics of the hybrid system, in order to guarantee maximum efficiency by favoring the most efficient heat source according to the external temperature. The panel allows the complete parameterization of the system, as well as the display of the operating status. Supplied with the heat pump, complete with bracket to be positioned directly inside the rooms.
