Alternatively, the heating terminal includes several sub-heating terminals, each connected to the water supply pipeline and the return water pipeline. The water heat exchanger section is connected in series or parallel to the return water pipeline. One sub-heating terminal and one water source heat pump heating unit constitute a group.
