Condominium – Turin

At an apartment building built in the mid-1960s and consisting of 6 apartments with a total usable area of ca 540 sq m, a heat pump with a nominal heat output of 82 kW was installed to replace a natural gas boiler for the production of heating in the winter season and DHW throughout the year. The intervention was carried out without changing the existing system consisting of radiators and included the construction of a domestic well (flow rate 2 liters/second) for heat exchange with groundwater. The investment was financed through a 7-year unsecured loan. The introduction of a heat pump has eliminated approx. 21 tons/year of CO2 emitted to the condominium’s chimney. This resulted in a recovery of two energy classes of the entire building. Economic benefits: a 39% reduction in the running costs of the current boiler was achieved. This saving, together with the use of the Conto Termico incentive, disbursed over 5 years, made it possible to cover the mortgage payment and the operating costs of the new power plant.
