TacoTherm Dual Piko

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.

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

Functions

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.
