The paper includes a general discussion of reasons for the application of heat storage and phase change material as storage medium. A part of experimental results obtained by measuring during the process of paraffin phase change was presented. It was observed that in order to obtain lower temperature stratification during the heating process it is necessary to increase the number of volume heat sources in the thermal storage. U radu je data opšta diskusija o razlozima primene akumulatora toplote i fazno-promenljivih materijala kao skladišnih medijuma. Dat je deo eksperimentalnih rezultata dobijenih merenjem tokom procesa promene faze parafina. Uočeno je da je potrebno povećati broj zapreminskih izvora toplote u akumulatoru kako bi se dobila manja stratifikacija temperature tokom procesa zagrevanja.
