This study is focused on showing technical and economic issues related to the use of low temperature PCM (Phase Change Material) storage system coupled to a condensing micro CHP. That one is a single cylinder engine of rated power and thermal outputs equal to 5 kW and 13.1 kW respectively, equipped with a three-way catalyst to meet the regulations on pollutants emission. Two different system layouts were built and economical-environmental performance was evaluated. Specifically, a traditional water tank and a PCMs array were analysed. A two-family house characterized by a normalized primary energy need equal to 50.523 kWh/m2 y was assumed as the end user. That energy need is referred to the climatic conditions typical of Middle region in Italy. Finally, the LCOE (Levelised Cost of Electricity), calculated over a system lifespan of 15 years, has been chosen as the main indicator to compare the different options optimizing the CHP switching-on strategies.
