This paper deals with the analysis of a specific hybrid energy system (HYS) from an overall energy efficiency aspect and also from an economical aspect. The hybrid energy system was purposely assembled from standard, market available energy technologies that are presently used in majority of building facilities, particularly in residential ones. Based on the previous aspect, the HYS was assembled using a standard split heat pump system (air-conditioning unit) with an integrated accumulation boiler for hot water preparation and using a small photovoltaic (PV) system. An overall energy efficiency analysis showed the HYS system to be highly energy efficient on average as overall energy efficiency ranged from 50% up to over 300% (the heat pump system acts as a kind of efficiency booster). An economic analysis showed that the HYS produced energy cost ranged from 0.035€/kWh up to 0.15 €/kWh, in investment conditions. A detailed energy efficiency and feasibility analysis showed that the herein analyzed HYS can be a viable option for small or medium building applications in mild climates.
