6.7.3 Mixer circuit with buffer cylinder
(Hydraulic plan 2)
The unregulated underfloor heating circuits are operat-
ed by the external heating circuit pump from the buffer
cylinder via a mixer. The flow temperature sensor sits
behind the external pump.
The heat pump responds to a demand for heat from the
buffer cylinder.
