Abstract: In this work results from modelling investigation of the cooperative work of heat pump “water to water” and solar thermal collectors in heating work conditions have been presented. An evaluation of the increased heat pump efficiency in cooperative work with solar collectors has been made. A variant of an installation scheme for practical implementation enables collaboration of the collectors and the heat pump has been proposed. The solar collectors can be used for producing of domestic hot water (DHW) as priority or to help the heat pump in heating work conditions.

Keywords: modelling investigation, heat pump “water to water”, solar thermal collectors
