A TEON heat pump with a thermal power of 82 kW was installed in a class B an apartment building built in the mid-1980s in the western outskirts of Milan. The heat pump replaced a methane-fueled condensing boiler, for the production of heating in the winter season and DHW throughout the year. The intervention was carried out without modifying the existing system, consisting of radiators, and involved the construction of a well for the extraction of groundwater. In the power station, a thermal accumulation has been inserted to allow greater availability of domestic water compared to the previous situation, resulting in the elimination of the methane line. The savings achieved in the first two years of operation stood at 55%. The introduction of the TEON heat pump has also made it possible to eliminate approx. 26 tons/year of CO2 emitted to the condominium chimney.
