EvoFlat FSF
The EvoFlat four pipe station are developed to increase efficiency in systems with heat pumps. The concept includes the use of two different temperature levels. A flow temperature of 55 °C is required for tap water heating. On the heating side, the surface heating system is operated with a flow temperature of 35 – 38 °C. In this way, the best possible COP for the heat pump is achieved. The EvoFlat-TM four pipe station is available as an in-wall version with a flush-mounted box or as a wall-mounted version.
Domestic hot water (DHW)
The hot water output is determined by the number of plates in the built-in heat exchanger. Due to the flow temperature of 55 °C, only type 4 is available. A built-in flow controller opens the flow through the heat exchanger on the heating and drinking water side. When the tap is finished, both flows are closed. The Evoflat 4.0 F is equipped with an intelligent controller that regulates the flow rate on the supply side depending on the hot water temperature and the tap volume. The station has an integrated differential pressure regulator on the supply side of the drinking water heating. This means that hydraulic balancing of the station is not necessary. These components ensure the optimum operating status for all home stations that are connected to the same system. To measure water consumption, are the EvoFlat4.0 F is equipped with a fitting piece for mounting a water meter in the cold-water inlet.

In order to enable a time dependent temperature control program, a zone valve with actuator is included and can be connected to a room thermostat as an option.
Domestic hot water (DHW)
The domestic hot water is prepared in the heat exchanger based on the flow principle and the temperature is regulated by the self-acting controller with integrated differential pressure controller - the TPC-M. Supreme ease of operation is obtained via the combined hydraulic and thermostatic regulation of the TPC-M controller. The flow-controlled part allows primary and secondary side flow through the heat exchanger, only when hot water is tapped and blocks the flow immediately after completion of the tapping process. The thermostatic part controls the domestic hot water temperature. The TPC - M controller with integrated differential pressure controller also compensates for flunctuating flow temperatures and differential pressures and thereby ensures a constant domestic hot water temperature at all times.
For registration of the cold water consumption the EvoFlatTM FSS flat station is equipped with a fitting piece for mounting of a cold water meter in the DCW inlet.
