ADVANTAGES ■ Compact installation depth ■ Large number of variants ■ Preconfigured for simple installation
■ On-demand, hygienic, decentra-lised DHW heating
■ Reduction of stored DHW volume to a minimum
■ Demand-driven calculation of energy costs
SYSTEM/BASIC DIAGRAM
HEAT INTERFACE UNIT
DESCRIPTIONThe heat interface unit in the Piko series suits practically any installa-tion situation thanks to its compact installation depth and versatile con-structions. The stations are available as individual fresh hot water mod-ules or heating modules as well as combination stations.Various selectable hydraulic com-ponents ensure on-demand prepa-ration of potable hot water, dis-tribution of heat energy as well as calculation of energy costs.
INSTALLATIONThe heat interface units can be in-stalled as a compact station or in a split design. For ease of transport, the compact version can be disman-tled conveniently into two parts and reassembled using the available plug connection. Ideally the station should be placed next to the outlets for the apartments. The individual modules can be assembled horizon-tally as well as installed at separate locations in the split design.
OPERATIONThe heat interface units in the Piko series are designed for preparation of potable hot water and distribution of heat energy in multistory residential buildings.Primary energy is supplied via a cen-tral buffer cylinder; decentralised DHW heating takes place in the do-mestic hot water module as required, according to the instantaneous wa-ter heating principle. In the case of combination stations, the heating surfaces in living areas are connec ted with the Underfloor heating circuit manifolds of the heating module or the radiator con-nections. The heating flow tempera-ture in the living area is regulated on a fixed-value or weather-controlled basis. Adjusting pieces are provided in the modules for on-site installa-tion of heat meters and cold water meters.

NOTE
REQUIREMENTS FOR FLOW MEDIA
The stations heat interface units use a copper-soldered stainless steel plate heat exchanger as standard. It must be checked prior to use in the framework of system planning whether the issues of corrosion protection and scale formation have been sufficiently taken into account in accordance with DIN 1988200 and current potable water analyses according to DIN EN 8065. See datasheet „Plate Heat Exchanger Requirements - Limit Values for Drinking Water Quality“.

EXAMPLE OF INTERPRETING THE FLOW RATE AND PRESSURE LOSS DIAGRAMS Given
■ Hot water dispensing volume: 22 l/min
■ Primary heating flow temperature: 70°C
■ Available primary differential pressure at the station of 300 mbar
Sought ■ Domestic hot water demand in l/h ■ Pressure loss on secondary side ■ Dispensing temperature
■ Primary heating return temperature in °C
■ Secondary pressure loss in mbarApproach
■ In Diagram B) a hot water dispen-sing temperature of 47 ºC can be read for the given hot water dis-pensing volume of 22 l/min at the intersection point with the diffe-rential pressure of 300 mbar, and the associated return temperature
can be read at the intersection point with the return temperature line at 300 mbar.
■ Diagram A) shows the pressure loss in the system on the secondary side and Diagram E) shows a DHW demand of 1150 l/h at the intersection point between the dispensing volume and the 300 mbar differential pressure.

EXAMPLE OF INTERPRETING THE FLOW RATE AND PRESSURE LOSS DIAGRAMS Given
■ Hot water dispensing volume: 20 l/min
■ Primary heating flow temperature: 55°C
Sought ■ Domestic hot water demand in l/h ■ Primary pressure loss in mbar ■ Primary heating return temperature in °C
■ Secondary pressure loss in mbar
Approach ■ In Diagram A) the hot water volume for the given DHW dispensing volu-me and the available primary flow temperature is 1,800 l/min at the point of intersection; in Diagram B) the primary pressure loss for the station is 600 mbar.
■ The pump delivery head of the FWM pump is 350 mbar for this volume of DHW. The required primary pressure ∆p at
the station is 250 mbar. ■ In Diagram C) the primary return temperature for the given dispen-sing volume and the selected flow temperature of 45 °C is then 31.5 °C.
■ In Diagram D) the secondary pressure loss for the given data is 225 mbar
