摘要

The method involves supplying energy from a central point whereby the heating medium is removed from the room return line or central return line (ZR) and supplied to a heat pump (2). The heating medium is heated with the pump and returned to the central return and/or room supply (RV) and/or central supply (ZV). Independent claim describes heating system for heating several classrooms with a heat pump (2) having on the input side a connection to the central return and on the output side in the flow direction behind this connection another connection to the central return whereby heating medium heated in the pump is supplied back to the central return.
