Solar hot water supply systems can provide a significant part of the thermal energy needed in the residential sector. The use of solar hot water supply systems can reduce the consumption of traditional energy sources and, consequently, reduce greenhouse gas emissions. The aim of this article is to assess the operation of the solar heating system operation to provide the needs of the hot water supply system of a residential building with thermal energy.

The work notes the development of non-traditional energy sources in Ukraine. There is a need to improve existing solar collectors and combine these units with structures of external fencing for energy-efficient buildings. Taking into account the popularity of construction with an increased area of glazing, the paper suggests the design of solar collector combined with the glass facade of the building. It gives data about change of the heat carrier temperature at the outlet of the solar collector.

The analysis of requirements for metrological parameters of digital temperature meters and temperature difference meters for solar collectors’ investigations been done in the article. Under the regulations requirements a minimum temperature drop not exceed 1,5 K, and for the maximum relative error of temperature measurement not more ±2% it provide the absolute error of temperature drop measurement near ±0,030 K, and their measurement unit list significant digit 0,01 K.
