Features

HIU Options - from Standard to Bespoke

Danfoss FlatStations come in 2 main types: Direct and Indirect both of which use a Domestic Hot Water (DHW) plate heat exchanger.
Space heating can be arranged either by Direct FlatStations, where the primary circuit connects directly to apartment space heating circuits, or alternatively by Indirect FlatStations, which enable the hydraulic separation of the primary circuit through a second plate heat exchanger.

Simultaneous Pressure and Temperature Control

Maintaining a high efficiency whilst having a reliable supply of hot water is crucial.
Mechanical controls ensure both system performance and comfort for residents.

Energy Metering

All Danfoss FlatStations can be easily be equipped with an energy meter, to fulfill billing requirements and enable ongoing energy optimisation efforts.
