Retrofit of a single house from 2006

The single house passes from energy class E to class A4 with heat pump and photovoltaic.

The challenge and the solution 

The owner of a single house of 150 m2 on one floor served by a natural gas boiler wanted to improve the energy efficiency of his home and lower heating costs.

The solution suggested by the designer was the installation of a Sphera T comfort heat pump with inverter technology to best adapt to the request of the system combined with an inertial tank of 100 liters and 30 photovoltaic modules of 400W each, for a total power of 12 kWp, combined with storage batteries and wallbox for electric car charging.

The heat pump is controlled via the HID-T connect chrono thermostat, allowing the client to manage the heat pump both with the touch display, via smartphone with the dedicated App, and via Alexa and Google Action voice assistant.
