The heat pump has four separate fluid circuits
•
Brine circuit – a water based mixture that transports energy from the heat source to the heat pump.
Refrigerant circuit – a circuit in the heat pump that through evaporation, compression and condensation takes
•
energy from the refrigerant circuit and supplies it to the heat transfer fluid circuit. The refrigerant is chlorine free.
Heat transfer fluid circuit – the water that transports the heat/energy to the heating system and the water heater.
•
•
Hot gas circuit – is a high temperature circuit for the hot water circuit's final heater. If the heat pump is not con-
nected to any water heaters, the hot gas circuit does not need to be connected.

Water heater
Danfoss DHP-R Eco can also produce hot water for an external water heater. The water temperature of the hot water tank is
controlled by the control switch and cannot be adjusted.
Hot water production stops when the control pressostat reaches its maximum operating pressure.

System overview
Danfoss DHP-R Eco can be configured in a number of different combinations, one of which is shown below. The image illus-
