Abstract: An analysis of the research of leading scientists was carried out in order to determine a rational methodology for experimental studies of hot water supply systems during the day for various types of thermal energy consumers, in particular for consumers of residential and public buildings. An experimental installation of a hot water supply system with a combined heat source based on a solar collector has been developed. On the basis of the conducted experimental studies, the adequacy of the developed mathematical model of flow distribution was confirmed. Therefore, the developed mathematical model of the flow distribution of circuit flow rates in the proposed DHW scheme with a combined heat source makes it possible to determine the degree of opening and the limits of regulation of balancing and control valves in different operating modes of the solar collector. The efficiency of a hot water supply system with a solar collector was calculated for the projected object of a typical section of a nine-story residential building in the T-Sol program. The main conclusions are given about the obtained experimental studies of a combined hot water supply system with a solar collector, as well as the effectiveness and expediency of using a mathematical model of flow distribution by the loop flow method [1, 3].
