A wall-hung 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:

– the wall-hung boiler: depending on installation requirements, the gas generator can be chosen from a range of boilers from 25 to 35 kW, for heating only or combined heating and hot water, for wall mounting (indoors or outdoors in partially protected locations) or built-in installation. 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 up to 2 independent hot/cold temperature zones;

– the heat pump: a wall-mounted air-water split unit from the FAMILY SPRINT series, available in models ranging from 4 to 14 kW, with a wall-mounted indoor unit for heating and domestic hot water production. The compact and quiet outdoor unit includes a Twin Rotary DC inverter compressor, electronic expansion valve, brushless motor fans and a finned coil optimised for heat pump operation even at outdoor air temperatures of -25°C. The indoor unit houses the main components of the hydronic system, a high-surface plate heat exchanger and a high-efficiency electronic circulator

– the hydraulic distribution module: you can choose 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 are responsible for supplying the system. For more complex systems, the BAG³ Hybrid distribution module is available: for indoor built-in or wall-mounted installations, or outdoor built-in installations, in 1 direct, 2 direct or 1 direct and 1 mixed configurations, equipped with low-consumption self-modulating circulators (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 energy, by installing the diverter valve kit.
