1 T T TACOTHERM DUAL PIKO HEAT INTERFACE UNIT 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 Preconfigured heat interface unit with compact installation depth for preparation of domestic hot water and apartment heating. DESCRIPTION The heat interface unit in the Piko series suits practically any installation situation thanks to its compact installation depth and versatile constructions. The stations are available as individual fresh hot water modules or heating modules as well as combination stations. Various selectable hydraulic components ensure on-demand preparation of domestic hot water, distribution of heat energy as well as calculation of energy costs. SYSTEM/BASIC DIAGRAM INSTALLATION The heat interface units can be installed as a compact station or in a split design. For ease of transport, the compact version can be dismantled 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 horizontally as well as installed at separate locations in the split design. OPERATION The heat interface units in the Piko series are designed for preparation of domestic hot water and distribution of heat energy in multistory residential 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 module in accordance with the continuous flow principle. In the case of combination stations, the heating surfaces in living areas are connected with the underfloor heating manifolds of the heating module or the radiator connections. The heating 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 meters and cold water meters. BUILDING CATEGORIES Apartment blocks Hotels and residential homes
