TacoTherm Fresh/Dual Nano

Preconfigured heat interface unit in slimline design for preparation of domestic hot water and apartment heating.

Description

This heat interface unit in the Nano series suits practically any installation situation thanks to its slimline design and versatile constructions. The unit is available as an individual fresh hot water module as well as with integrated panel heating manifold.
Various selectable hydraulic components ensure on-demand prepa­ration of domestic hot water, distribution of heat energy as well as de­mand-driven calculation of energy costs.

Advantages

  • Slimline design
  • Large number of variants
  • Preconfigured for simple installation
  • On-demand, hygienic preparation of domestic hot water
  • Demand-driven calculation of energy costs
  • Use as a gas boiler replacement unit (TacoTherm Fresh Nano)

Functions

The heat interface unit in the Nano series is 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 the combination station, radiators or underfloor heating systems in the apartments are connected to the integrated connections. The combination station meets the heat requirement for the apartment in this way.
The heating flow temperature 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.
