wall-mounted hybrid system

A wall-mounted hybrid system is a multi-energy hybrid system for heating, summer cooling and domestic hot water production. This system is created by combining three main components together:

– the wall-mounted boiler: depending on the installation needs, the choice of gas generator can be made by choosing between boilers from 25 to 35kW, heating only or combined, for wall-mounted installation (inside or outside in partially protected places) or built-in. The boilers have a modulation ratio of 1:5 or 1:8, 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 climatic conditions, and manage the system with up to 2 independent hot/cold temperature zones.

– The heat pump: monobloc outdoor air-water type from the NXH 005÷015 series, used for heating, cooling and pre-heating domestic hot water for domestic use if a DHW tank is present. NXH 005÷015, specific for hybrid systems, is able to communicate with the system intelligence via bus, and is available in the powers of 5, 7, 11 and 15 kW.

– 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 direct one-way 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 internal built-in or wall-mounted installations, or for external built-in 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.

– The system is able to interface with a photovoltaic system in order to change its energy strategy, encouraging the use of the electrical source when self-producing.
