FIELD: heating.
SUBSTANCE: invention is referred to heating engineering and, particularly to water preparation plants used for heating and may be used in systems operating on heat from warmed-up underground thermal waters used for buildings and structures heating by decentralized methods. Technical result: improvement of buildings and structures heat supply and simplification of plant design for heating purposes. Water warming up method for heating includes generation of flow with circulating primary coolant, for example warmed-up underground thermal water, and flow containing secondary coolant circulating in closed circuit, for example system water, heat exchange between flows and supply of secondary coolant of warmed-up system water to heating devices of heating system. Firstly system water is warmed up to 40-45°C from heated underground thermal water in well heat exchangers, then heated system water is supplied to thermal pump intake where its temperature is raised to 70°C and supplied to heating system radiators by means of system pump. Associated plant for implementing the said method is also described.
EFFECT: improvement of heat supply system for buildings, structures and simplification of water preparation plant design.
