ADVANTAGES ■ Compact installation depth ■ Large number of variants ■ Preconfigured for simple installation

■ On-demand, hygienic preparation of domestic hot water

■ 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 modu-les or heating modules as well as combination stations.Various selectable hydraulic com-ponents ensure on-demand pre-paration of domestic hot water, distribution 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 dis-mantled 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 domestic hot water and distribution of heat energy in multistory residen-tial buildings.The primary energy supply is by means of a centralized storage tank, while the drinking water is heated on demand in the fresh hot water modu-le in accordance with the continuous flow principle. In the case of com-bination stations, the heating sur-faces in living areas are connec ted with the Underfloor heating circuit manifolds of the heating module or the radiator connections. The hea-ting flow temperature in the living area is regulated on a fixed-value or weather-controlled basis. Adjusting pieces are provided in the modules for on-site installation of heat me-ters and cold water meters.

BUILDING CATEGORIES ■ Apartment blocks ■ Hotels and residential homes

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 drinking 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 ■ 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 hot water demand of 1150 l/h at the intersection point between the dispensing volume and the 300 mbar differential pressure.
