TacoSys Piko

Preconfigured heating module with compact installation depth for 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.
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
  • 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.
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.
