A hybrid system consists of a hybrid condensing boiler in combination with an external heat pump and internal units (split and radiators). This system allows for hybrid heating, air cooling and the production of domestic hot water (DHW) in a single system.

To produce heat, a hybrid air conditioning system uses both the condensing boiler, fed with methane gas (2), and the external condensing unit fed with refrigerant gas (1): specifically, the boiler, connected to the water mains (5), produces hot water (4) for the hydraulic circuit (3) of the radiators and domestic hot water (6). Cooling, on the other hand, is guaranteed only by the external unit and by the internal evaporating units.

The resulting advantages are the following:

- easy installation, space saving and cost optimisation;
- water heating with ecological refrigerant;
- all the advantages deriving from the "hybrid system" in terms of efficiency and savings on heating costs;
- access to state incentives for energy saving measures.

When winter arrives, a hybrid system is 35% more efficient than a condensing boiler in heating and up to 20% in instantaneous DHW production. When summer arrives, indoor units, whether wall-mounted or ducted from false ceilings, guarantee maximum performance in terms of climatic comfort and air quality.
