Fouling in plate heat exchangers remains a significant process in the heating industry. With respect to this phenomenon the paper presents experimental research on 2 plate heat exchangers, which are components of the district heating system in Cracow. The primary issue that this research focused on was an analysis of operating conditions such as volume flow rate, temperature of fluids, heat transfer coefficients and thermal resistance of scale deposits in the process of domestic hot water production. As a result fouling thermal resistance over time was determined.
