FIELD: heating equipment.
SUBSTANCE: invention relates to heating system (100), which includes district cooling network (1) and local heating system (200), configured to heat the building and/or provide hot tap water. Proposed system comprises feed pipeline (5) for cooling fluid inlet flow, having first temperature, and return pipeline (8) for cooling medium flowback, having a second temperature higher than first temperature. Local heating system (200) is equipped with heat pump (10), in which inlet (10a) is connected to return pipeline (8) of district cooling network (1), and outlet (10b)—to its supply pipeline (5).
EFFECT: invention allows to use as input energy to heat pump heat energy available in return pipeline of district cooling network, which was considered as waste energy, and also to increase expected service life of heat pump.
